Shortly after the discovery of X–rays, another form of strong rays were discovered. In 1896, French scientist Henri Becquerel discovered natural
radioactivity. Many scientists of the period were working with cathode rays, and other scientists were gathering evidence on the theory that the atom
could be subdivided. Some of the new research showed that certain types of atoms break by themselves. It was Henri Becquerel who discovered this
experience while investigating the properties of fluorescent minerals. Becquerel was researching the principles of fluorescence, wherein certain
minerals glow (fluoresce) when exposed to sunlight. He utilized photographic plates to record this fluorescence.
One of the minerals Becquerel worked with was a uranium

Martyrs To X-Rays
Martyrs To The X–Rays The discovery of X–rays was costly. Many lost their lives in the process and those who survived with severe physical
deformities were considered fortunate. Their determination is inspiring and their work was a life changer.
The Beginning Wilhelm Conrad Roentgen discovered X–rays on November 8, 1895. About 14 days after Roentgen first noticed radiation activity, a
man by the name of Friedrich Walkhoff performed the first dental X–ray. He did the X–ray on himself first for twenty–five minutes and then on
patients for thirty. Mr. Walkhoff only noticed hair loss on his patients around the exposed area, nothing he considered significant (Sansare, Khanna, &
Karjodkar, 2011, p. 1). Minor effects of radiation were first noticed in 1896 by Nikola Tesla... Show more content on Helpwriting.net ...
It was not until 1904 when William Rollins leaded the tube housing, installed the collimator, and did many experiments on pregnant guinea pigs to
conclude that X–rays can kill fetus'. Rollins was the first to give many contributions to radiation protection. In 1907 an X–ray manufacturer by the
name of Rome Wagner had the first idea of film badges. He would carry a photographic plate in his pocket to see if he was getting too much exposure
and then develop it each night. Wagner was unable to perfect his idea because he died six months later fromcancer (Kathern, & Ziemer, 1980, p. 3). In
the 1920's other methods of protection were introduced. The film badge became a routine monitoring device. The unit to measure radiation was
established and named the Roentgen, and the first tolerance dose was created (Kathern, & Ziemer 1980, p. 4). One might classify radiation protection
as quite the traveler since its journey transcended through both the Pioneer Era and the Era of Progress. Today's advancements include a reduction in
exposure time to milliseconds and a switch to digital (Sansare, et al., 2011,

X-Ray Analysis Essay
A primary survey of the remains is undertaken, (noting sex, stature, age, unique characteristics etc.) X–ray analysis will then be performed on the
remains through the body bag, to prevent the loss of evidence. There are different types of imaging techniques, these include multidetector computed
tomography (MDCT) scanning, fluoroscopy, radiography (X–ray) (Wozniak et al., 2015). One common method for undertaking the secondary survey is
radiography. This comprises of examining the cadavers for any unique characteristics, which may have been noted in ante mortem medical records.

The macroscopic, microscopic and radiographic appearance of bone must be recorded in reference to trauma and disease, this may then be compared
to ante mortem records. When considering the pathology aspect of the investigation the type of disease must be contemplated (lytic, proliferative,
deformative, trauma) and the ratio of bone being lost to bone being formed. The type of bone being formed is also important and how the bone loss
and or formation has transformed the size and shape of the bone. When surveying the remains, it must be acknowledged which parts of the body are
affected and the position of the ailment within each bone. The location in which the symptoms are manifested may be an indicator as to which
condition the deceased was affected by (Ferguson and Black, 2011).
Bone morphology is another method which may be used for identification, the shape of the bones are unique and may be used as a "fingerprint" to be
compared to ante mortem medical records (Cattaneo, 2007).
3. Diseases of Bone
Bone diseases affect the remodelling of bones. In healthy bone, bone is laid down (ossified) and resorbed as needed. In diseased bone, the natural
balance of resorption and ossification is affected leading to there being a net loss or gain of bone. Bone diseases are generally either proliferative or
erosive although there are some, which are a combination of the two (University of Cambridge, 2004, Waldron,

The Hard X–ray Nano–probe Beam line is a precision platform for scanning probe and full–п¬Ѓeld microscopy with 3–30 keV X–rays. The
combination of high–stability X–ray optics and precision motion sensing and control enables detailed studies of the internal features of samples with a
resolution approaching 30 nm. The Hard X–ray Nano–probe is a combination scanning probe and full–п¬Ѓeld imaging microscope for п¬‚uorescence
mapping, nano–diffraction and transmission imaging. Future improvements in X–ray optics fabrication and precision sensing and motion control will
be incorporated into the beam line to enable imaging at a resolution approaching 10 nm [1].
X–Ray Fluorescence Microscopy (XFM):
The basic principle behind the X–ray Fluorescence microscopy (XFM) is the exposure of X–ray beam on the sample. The technique is employed to
establish the elemental concentrations for wide range of samples in multiple locations of cells and tissue samples. It has excellent sensitivity for the
detection of trace elements. This technique is enabling to image the whole cell along with the quantification of elements on the per cell basis. This is
because of the large penetration depth of the hard X–rays used. Cryogenic approach is used to investigate the samples in their natural or hydrated state.

If it weren't for x–rays, how would doctors be able to detect abnormalities within a patient? The x–ray was accidently discovered by physicist Wilhelm
Roentgen in 1895. He discovered it when he was experimenting with electric flow currents in a cathode– ray tube and saw a piece of barium
platinocyanide giving off light while he was working with the tube. His theory was that when the electrons of the cathode–ray tube hits the wall of the
tube an unknown radiation, went across the room and hit the chemical, and then caused a fluorescence.(paraphrase, Encyclopedia Britannica). Also, he
thought since he couldn't find any light refraction or things similar to light, that this new found thing was unrelated to light. He named it X–Radiation,
this is also known as Rontgen Radiation. (Fun fact: Roentgen can be spelled without the first e.) Rontgen also experimented further and learned that
paper, aluminum, and other metal things were transparent with this new invention. His first x–ray was of his wife's hand. He looked at the bones in
her hand and he looked at the insides of metal objects with his new found machine. Also, Roentgen received a Nobel Prize for his discovery. However,
Roentgen wasn't the only man to discover something in chemistry history. Who invented the telescope? It's currently a controversial topic amongst
astronomers of the world. Some say Galileo Galilei invented the

The History of the X-Rays Essay
During the cold winter of 1895, a German scientist by the name of Wilhelm Conrad Roentgen was working with a cathode–ray tube when he noticed
nearby crystals were glowing. When Roentgen reached for the crystals he was amazed when the shadow cast on the crystal was not of his whole hand,
but just his bones. Roentgen covered the tube with heavy black paper and saw that the crystals still glowed and the shadow of his hand bones still
shown through, he then determined that a new ray was being emitted that could penetrate through thick materials. (1.) He later found that the rays
could pass through most anything, but would cast a shadow of solid objects; these shadows could then be captured on film. Among the solid objects

The Coolidge tube could operate to energies up to 100,000 volts. General Electric went on to make x–ray tubes capable of operating at energies up to
1,000,000 volts, which gave the x–ray technology enough stability to become industrialized and mass produced.
With this stability and mass production, x–rays machines became very common everywhere. From large factories, to doctors offices, all the way to
the corner store of small towns, where children and adults alike could insert a coin into a machine and view the bones in their feet. (3.) Because of
their relative adolescences in the world, not much was known about x–rays or their effects on the human body. The first theories about the rays' effects
on the human body were that they had beneficial applications. With this being the only theory about their effect, widespread use went on, unmonitored,
and unregulated. This unregulated use led to injuries but because of their slow onset the injuries were never attributed to x–rays. While some scientists
tied certain skin burns to over exposure of x–rays it wasn't until popular minds of the world like Thomas Edison, Nikola Tesla and William J. Morton
expressed that they experienced eye pain when dealing with the rays for extended periods of time that people began to connect the dots and understand

A scientist would need a glass tube with positive and negative electrodes. The tubes were called cathode tubes, and they were common in the late
1890s. The air leaves the glass tube, and a florescent glow is produced when a high voltage runs through the tube. The scientist needs to cover the
glowing tube with a heavy, black paper or cardboard. Then the scientist will see the green colored fluorescent light illuminating from the box. This is
known as the X–Rays which energizes the phosphorescent materials in the room. The newly discovered ray would pass through objects, and it can cast
a shadow of most solid objects. The ray consists of electron passing through the matter underneath the cathode tube. It can pass through human tissues,

For this reason patients must be aware that there is not a such thing as a safe amount of ionizing radiation. No matter how small the amount, x–rays
produce ionizing radiation which is damaging to human tissue and therefore all procedures involving x–ray exposure to the patient are considered
dangerous. This being the case, those who administer x–rays should be very knowledgeable about the energy they are dealing with, sadly this is not
always the reality we live in. The article titled U.S. Technologists' Radiation Exposure Perceptions and Practices states that "Current literature
documents excessive radiation doses from medical uses and a lack of necessary education for physicians, fluoroscopists (ie, cardiologists, radiologist,
neurologists, and others trained to perform fluoroscopy) and patients concerning the benefits and dangers of medical radiation."5 This is a huge
problem in the concept of patient safety when dealing with the use of ionizing radiation for medical procedures. If those administering the x–rays do
not completely understand their dangers than how is a patient who most likely knows very little about the subject suppose to be the safest possible

A Brief Note On X Ray Vision Goggles
Abstract
MRI's today are the solution to X–Rays by having radio waves go back and forth transmitting signals that allow Doctors to see inside the human
body. There are not many downsides of MRI's, however MRI's do not fit in the average waiting room by being circular tube like machines that
take about 1 hour to produce a clear image of a patient's problem. MRI's are great when it comes to mental disabilities but when it comes to broken
bones, it is too time consuming to wait in the machine for an hour to find out about a torn ligament or broken bone in a patient's body. A new vision
will take away the harmless effects of an MRI but also have it for every day needs in a doctor's office. X–Ray Vision goggles would allow a doctor to
see a patient's broken bone or ligaments without effects of X–rays. Present Technology
Wilhelm Rontgen, a German physicist, had multiple experiments in 1895 he and found a type of radiation which he labelled as the letter X, because
he did not know what it was. His X–rays were soon discovered by Doctors which primarily used them to look inside the human body. One original
component that has not changed since has been how they are developed and made.
X–Ray's are used to generate pictures that show the inside of the human body such as finding broken bones. In Otto Zhou of the University of North
Carolina, Dr Zhou and his colleagues are bringing X–radiography into the world of modern electronics. In doing so, there is a hope to create X–ray

discovery the x–ray. Back when the x–ray technique was new, people didn't realize the damage radiation could cause. This changed soon when it was
discovered how people were severely injured from the exposure, as they were not wearing any protective shield. In the beginning the doctors or
physicists worked and operated the x–ray machines themselves, but as the demand grew, the need for actual x–ray machine operators were needed. The

One of the reasons could be the amount of time it took for an injury to occur after exposure. However, more and more frequent cases describing skin
irritation associated with a bad sunburn started to occur. One scientist by the name of Elihu Thoms decided to expose his little finger under radiation
30 minutes a day, for several days. The results were pain, swelling, erythema and blistering. This convinced him, and others the dangers of radiation,
and by 1900 the majority of the medical and the scientific community, were familiar of the dangers of over exposure. The decrease of exposure time
and incidence was the most evident ways to limit the amount of radiation, or dose, to a patient. They were even experimenting with enclosed tubes and
distances to protect themselves from the exposure. Filtration to the x ray beam was actually encouraged before the 1900's and so was the size of the
beam. Some other methods used to minimize patient exposure was using intensifying screens and higher x–ray generating voltages. Even though
ex–ray protection was well known by 1905, it would still take many years for it to be universal. Even as late as the 1940's it was not uncommon to find
x–ray units without any safety measures at all. There are three distinctive periods of radiation protection. The evolution of x–ray protection is split into
three

Polarization of X-Rays
Polarization of X–rays was first demonstrated by Barkla. He was performing experiments on the secondary X–ray radiation phenomena (C. G. Barkla
1905). He used a block of graphite that scatters the primary X–ray beam from an X–ray tube. The scattered intensity of the X–ray beam was measured
in two mutually perpendicular directions. He denoted the scattered intensity in a parallel direction to the tube axis I_pand the one scattered at right
angles I_s. The degree of polarization for X–rays emitted at an angle Оё to the direction of the electron beam is given as (Agarwal 1991):
P_(pol(Оё))=(I_s–I_p)/(I_s+I_p )
Barkla found that for Оё=90В°,I_p was larger than I_s by в‰€20%. This discovery that X
–rays can be partly polarized proved that they are transverse
electromagnetic waves. However, Barkla actually studied and measured the polarization of the bremsstrahlung (continuous) radiation.
When electrons emitted from a heated cathode filament are accelerated by a potential difference U and impinge onto an anode target (for example
tungsten), the motions of the electrons with in the target are influenced by the strong Coulomb fields of the atomic nuclei. As a result, the electrons are
decelerated within small distances and; consequently, a broadband bremsstrahlung or continuous radiation is produced. Figure 2.3. PENELOPE

Advantages Of X-Ray Photoelectron Spectroscopy
Adhesion studies Advantages of X–ray photoelectron spectroscopy (XPS) X–ray photoelectron spectroscopy (XPS) is an analytical technique that
originated in the photoelectric effect, described by Einstein way back in 1905 [2]. Its measurements for characterization of solid surfaces are
undertaken under vacuum conditions by retarding field methods. The application of the XPS techniques has several advantages as discussed in this
topic. One of the advantages of this technique is that, the x–ray sources it employs, which include Al KпЃЎ (1486.6 eV) and Mg KпЃЎ (1253.6 eV)
have very narrow x–ray lines below 0.9ev [1]. Therefore, this sources provide a good energy resolution hence making this technique applicable in many
areas. Also, the electrons of the elements present in the solid surface are emitted at characteristic energies thus many elements can be identified easily.
Moreover, XPS technique allows identification of all chemical states at any given element through quantification of the high resolution peaks [2]....

Normally, the probing depth is between 4nm to 10nm and may even go to 20nm, indicating that this technique is sensitive to both surface and near
surface layers [4]. XPS is a relatively non–destructive method of sample characterization, which depends on the nature of the sample and the power
operation of the X–ray tube. Also, it is effective in identifying elements and their chemical states on surfaces and in quantitative analysis [5]. Further,
XPS is able to detect the variance in chemical state between different samples. Furthermore, the oxidations states of different molecules can be
differentiated in this

The Discovery Of X Rays
X–rays is one of the many discoveries that revolutionized the way the humanity functions technologically, economically and socially in a fast
changing world. This invention was thanks to Dr. Rontgen. His invention changed the medical and astronomy field drastically and therefore he was
awarded the first Nobel prize in physics. He was awarded this incredible and highly valued award in the year 1901 after producing, detecting and
then discovering these high frequency wavelengths produced by electromagnetic radiation. This Physicist and scientist later to be recognized as
doctor gave the world the gift of this amazing, invisible and powerful rays that would change the world for ever. Willhelm Conrad Rontgen was born
in March 27 on the year 1845, at Lennep, in the big city of Remscheid which is located in Germany. He was an only child. His father was a merchant
who sold and manufactured cloth. His mother, Charlotte, came from family in Amsterdam. When he was very young his family and him moved to the
Netherlands. There he assisted the Martinus Herman van Doorn institute, which was a school. A few years later he entered another school at Utrecht
but was unfairly expelled. As he got older Dr. Rontgen studied at ETH Zurich which was Sencherman 2. also known as the Federal Polytechnic institute
in Zurich. He started his career as a mechanical engineer. In 1869 he graduated with a Ph.D. from that same Polytechnic after having and outstanding

X-Ray Tube Essay
X–ray tube is designed to lower the amount of heat produce, this can be accomplished by the rotating of the anode which gives off heat. The X–ray
tube is designed with the anode attach to the rotor and cathode on the other side of anode. This design determines the characteristics of X–ray beam.
The cathode is a normal cathode is made up of negatively charge small coil wire called filaments, which is housed in focusing cup. The filament is
negatively charged coil of wire which becomes heated when the electrical current passes through and when that energy becomes enough to expel the
electrons from the filament its called Thermionic Emission. The function of cathode is to push out electrons which are produced by electric circuit and
to turn those electron into a beam. The filament is contained in the cathode, usually design using a material known as Theorated tungsten. This
theorated tungsten allows for a high temperature without the filament melting and there are different sizes of filament which can help to vary the
spaceial resolution according to what is being x–ray.
The anode has two primary functions, one is to convert electronic energy into x–radiation and the second one is to dissipate the heat created in the
process. The part of the x–ray tube where x–radiation is produced is a large piece of metal that connects to positive side of electric current. The anode
provides a mechanical support for a target, the material of anode enhances the conversion of energy and

The Negative Impact Of X-Rays On The Human Body
l
.
Abstract X–rays are commonly assumed to be dangerous and a cause for cancer, but how much exposure is actually dangerous to humans? Every year
7 out of 10 Americans receive at least one X–ray, and each X–ray exposes the patient to a small amount of radiation. People are also exposed to
naturally occurring radiation that comes out of rocks and from outer space. Over time, radiation exposure builds up, and a patient can eventually have
an increased risk of cancer, after a certain threshold is reached. The cell damage is not easy to control, and can be deadly once it becomes cancerous. Is
exposure to X–rays it worth it? X–rays are incredibly helpful medical tools, and can be safe and important for diagnosing some injuries and ... Show
The World Nuclear Association has recorded that most of the earth receives about 1.5– 3.5 millisieverts of radiation a year. The Kerala and Madras
States in India receive about 15 millisieverts a year, the highest naturally occurring rates anywhere on earth. This natural radiation is caused by sand
that contains thorium, a radioactive element. Parts of Brazil and Sudan also receive large amounts of radiation, due to their geology. Natural radiation
is safe, most of the time, and most of the radiation comes from rock, (even the granite in a counter top) or from space.
What are Health Impacts?
Large amounts of X–ray radiation can cause mild effects such as headaches and vomiting, but they can also cause more severe effects such as hair
loss, low blood pressure and even death. Depending on how much radiation people are exposed to and how long of a period people are exposed to it,

X-Rays: The First Radiology
One of the first radiology departments was created at the Glasgow Royal Infirmary in 1896. Dr. John Macintyre, head of radiology at Glasgow,
created the first x–ray of a kidney stone, an image showing a penny in the throat of a child, as well as an image of a frog's legs in motion. An
American physiologist experimented with x–rays in order to trace food as it traveled through the digestive system (Waters, 2011). In 1896, Dr.
Hall–Edwards became one of the first physicians to use x–rays to diagnose a patient, when an x–ray revealed that a needle was embedded in the
patient's hand. X–rays quickly became a vital tool used by doctors, to diagnose patients (Roentgen's discovery of the X–Rays, 2006). In 1897, x–rays
were first used to locate bullets

How Did Roentgen Contribute To The Discovery Of X-Rays
He continued his experiments by using photographic plates, as opposed to screens, which resulted in the creation of a photograph. Roentgen received
quite a lot of recognition for his discovery. In fact, he received many scientific prizes and awards. Also, many streets were named after him and he was
granted honorary memberships into societies both in Germany, and abroad. However, Roentgen remained a modest man (Wilhelm Conrad Rontgen,
n.d.)
The discovery of x–rays revolutionized the entire medical profession, and provided a basis for diagnostic radiology. The x–ray showed the internal
structures of the human body, without having to resort to surgery. Roentgen's discovery of x–rays was a discovery that would benefit mankind for years.

Last of the diagnostic imaging tools is the MRI. MRI, which stands for Magnetic Resonance Imaging, was a technique developed in the 1950?s by
Felix Bloch, and is the most versatile, powerful, and sensitive tool in use. The process of MRI was originally called NRI, Nuclear Resonance Imaging,
but was found to be to confusing due to the fact that MRI?s don?t use radioactivity and ionizing radiation. The MRI generates a very powerful
electromagnetic field, which allows the radiologist to generate thin–section images of any part of the body. Also it can take these images from any
direction or angle, and is done without and surgical invasion. Another plus side to the MRI is the time it takes to perform, where as a CAT scan may
take 30–60 min. A MRI may only take 15 minutes max. The MRI also creates ?maps? of biochemical compounds within a cross–section of the body.
These maps give basic biomedical and anatomical information that provides new knowledge and may allow early diagnosis of many diseases. The
MRI is possible in the human body because our bodies are filled with small biological ?magnets?, the most abundant and responsive of these are the
protons. The principal of the MRI is that it utilizes the random distribution of protons, which have basic magnetic properties. Once the patient is placed
in the cylindrical magnet, the diagnosis process follows 3 steps. First, MRI

The Discovery of X-Rays Essay
The Discovery of X–Rays
X–rays were discovered by accident in 1895 by the German physicist Wilhelm Conrad Roentgen. Roentgen was already an accomplished scientist with
forty–eight published papers. He had a reputation among the scientific community as a dedicated scientist with precise experimental methods.
Roentgen had been conducting experiments at the University of Wurzburg on the effect of cathode–rays on the luminescence of certain chemicals.
Roentgen had placed a cathode–ray tube, which is a partially evacuated glass tube with metal electrodes at each end, in a black cardboard box in his
darkened laboratory. He sent electricity through the cathodre–ray tube and noticed something strange his laboratory. He saw a flash of light ... Show
During an experiment he placed his hand between the source of the X–ray, the cathode–ray tube and a screen and saw the faint outline of the bones of
his hand. It was the first X–ray picture. The more dense bone absorbed more X–rays then the less dense flesh producing an image of his hand. He soon
learned that photographic plates were sensitive to X–ray as they are to light and was thus able to make the first X–ray photography. These first
"Roentgen exposures" were of various metal objects that were locked in a wooden case and of his wife's hand.
On December 2, 1895, Roentgen sent his paper titled, "Concerning a New Kind of Ray: Preliminary Report" to the Physical–Medical Association who
published it in their 1895 volume of the minutes of the association. His report was soon published in several magazines around the world and in daily
newspapers causing a tremendous stir. On January 23, 1896, about a year before the Invisible Man was published, Roentgen delivered his first public
lecture on X–rays at the meeting of the Physical–Medical Association. During the lecture, he asked a well known anatomist to have his hand
photographed using X–rays. The photo came out good and was passed around. The hall erupted in applause and cheers for Roentgen for everyone saw
the practical uses of this new ray. Less than twenty days after the lecture, an X–ray machine was used in the United States to locate a bullet in a

The Discovery Of X Rays By Wilhelm Roentgen Essay
While the discovery of x–rays by Wilhelm Roentgen in 1895 was a major breakthrough in medical diagnosis and treatment, it was not without its own
problems. The cancer–related deaths of earlier scientists like Pierre and Marie Curie, and Thomas Alva Edison who were directly exposed to
radiation from their discoveries on radium and calcium tungstate respectively, were the proof of how dangerous the new breakthrough could be
when handled without the necessary precautions. The work of Martha S. Linet, Kwang Pyo Kim, Donald L. Miller, Ruth A. Klienerman, Steven L.
Simon, and Amy Berrington de Gonzalez traces the history of cancer risk in medical workers through the years from the early discovery of
radiation. According to the findings done by Linet et al, recent research has found that cancer risk per dose of medical workers when measure is the
same as that from the survivors of the Hiroshima atomic bombs. Apart from the research done mostly on the survivors of Japan's Hiroshima atomic
bomb, very little research has been done specifically to fully comprehend the scope of the devastation that comes along with a life time career as a
medical radiation worker. Given this limitation, the research studies done by Linet et al focuses primarily on the impact on radiologist and radiologic
technologists. Nevertheless, the limited research findings report a substantial decline in the number of cancers related deaths amongst medical
radiation workers over the years. Linet et al's research

How Did X-Rays Change The World
Imagine a machine that made what was once invisible, visible. Wilhelm Roentgen discovered the X–ray in 1895. X–rays impacted the field of medicine
greatly. The discovery of X–rays significantly changed how we could see the human body, treatment options, and how we viewed X–rays. Wilhelm C.
Roentgen was a German physicist. He was born on March 27, 1845, and died on February 10, 1923. He was married to, Anna Bertha Ludwig. He
received education from the University of Zurich, the Institute of Martinus Herman van Doorn, ETH Zurich and the University of Strasbourg. He
received the Nobel Prize in physics in 1901 for discovering X–rays.

human body using X–rays made diagnosing and monitoring medical problems easier and more efficient. They no longer have to make incisions, they
can just use X–rays to see what going on inside of your body. Doctors are able to see inside the body because the way the X–rays react with the density
of the organs and bones inside of you. "Soft tissue, such as skin and organs, cannot absorb the high–energy rays, and the beam passes through them.
Dense materials inside our bodies, like bones, absorb the radiation." (Wonderopolis.org). This is why we are able to see bones and other things inside
our bodies. "Black areas on an x–ray which is flesh and soft tissue show where the X–rays passed through. White areas on x–rays show where denser
tissues like bones have absorbed the X–rays." (RadiologyInfo.org). The white areas that show up on the X–rays are what allows the doctors to see the
inside of the body. The doctors view the body because of how the radiation reacts with the differences in density of organs, flesh, bones,

Physics Of X Ray Fluorescence
X–Ray Fluorescence (XRF) Spectrometry
The JSX–3222 analyzer is an energy–dispersive fluorescent X–ray spectrometer developed to analyze cadmium (Cd) included in plastic and the electric
wire film material, etc. promptly. The range of elements that can be measured is from sodium (Na) to uranium (U).Liquid–nitrogen cooling for the high
performance detector is required only during the analyzing time. The vacuum and atmosphere are switched to the measurement atmosphere by the
operation of one button. When X–rays (primary X–rays) are illuminated from the X–ray tube to the specimen, fluorescence X–rays having wavelengths
(energies) peculiar to the constituent elements of the specimen are generated from the elements.
Qualitative analysis can be made by investigating the wavelengths of the fluorescence X–rays and quantitative analysis by investigating the X–ray
dose. The energies are investigated by two methods. One is to optically separate them and the other is to use the energy separation characteristic of the
X–ray detector. The former is called the wavelength dispersive method an: the latter the energy dispersive method. The element analyzer employs the
latter method. As seen from the figure, since the energy dispersive X–ray spectrometer has no moving parts employs a simple optical system, its
structure is simple and compact. And since the detector can be installed the specimen, the X–ray solid angle of collection can be made large, thus
offering many features such as

Taking a Look at X-Rays
X–rays have come a long way since 1896; new technology, materials and even machines have changed the concept of a typical x–ray image since the
discovery. New imaging techniques described in Origin and Development of Medical Imaging apply in computerization to conventional X–rays images.
These images have incredibly improved and can be enhanced by digital techniques and the extremely great effect of these x–rays is the reduction of
exposure to radiation to the patient (Doby, Alker 118). In the article, "Another Look Inside" quotes
Conventional CT scans are used to shape the place where a dose of radiation needs to be concentrated in to attack a tumor without damaging any
healthy tissue around that area. The scan and treatment cannot be done at the same time due to interference with each other. But there is no
interference problems with the field–emission X–rays, they can be used to take high–resolution images while the treatment is starting, which means
those who are administering the treatment will automatically know when to continue and stop (The Economist). In "Another Look Inside", states the
rays are created by the energy of impact. These X–ray machines have progressed over the years. Tomography, CT scans, scanners that are used in
hospitals have collected x–ray images that have been taken from different angles and converted into three–dimensional images of internal organs of a
patient (The Economist). A prototype machine that has 52 field–emission X–ray sources is

Mammography: X-ray and Breast Tissue Essay
Mammography
Breast cancer is a common malignancy diagnosed in women. In the United States one in eight women who live to the age of 95 will be diagnosed with
breast cancer. Even with the high rate of diagnosis, it remains the most treatable due to early screening and improved detection methods.
Mammography is the precedent for screening and diagnostic procedures in the breast cancer field. Its enhancements through the years, together with
higher resolution, faster, lower–dose screen–film combinations, have contributed to earlier cancer detection in women.
Dr. Wilhelm Conrad Roentgen discovered x–rays while working with a Crookes tube in his laboratory on November 8, 1895. Eighteen years later

Digital mammography has given the physicians the capability to adjust contrast, transmit images, and to magnify suspicious areas of the breast. This
technology has also given the radiologist the capacity to digitally mark areas of concern directly onto the digitalized image which is conveniently
stored on the computer for easy retrieval for the next mammogram for comparison.
A mammography unit is a rectangular box that houses a vacuum tube in which x–rays are produced. The unit is designed to rotate to optimally image
all angles of the breast tissues. These units are integrated with a compression device that firmly holds the breast in place. This act of flattening the
breast is extremely important to improve optical density, contrast, and spatial resolution and lower the patient's radiation dose. Most importantly, to
ensure that small abnormalities won't be covered by overlying breast tissue. In routine screening procedures, each breast should be screened using the
craniocaudal (CC) and mediolateral oblique (MLO) projections; however, there are 13 projections that can be performed. Once the breast is
positioned, a low dose of ionizing radiation is sent through the tissue from the vacuum tube to produce black and white images of the tissue on x–ray
film. Different parts of the body absorb the x–rays in varying degrees. Bone absorbs much of the radiation while

would come at great expense to the clinic (the hiring of another trained surgeon). A less expensive option would be to take on another Senior Resident
and alter the responsibility of the surgeon. Currently, the surgeon sees new and follow–up patients, while the senior resident tends to all the follow up
patients that the surgeon does not meet with. By assigning all follow–up patients to two residents, we allow the surgeon to decrease his utilization
(–23.53%) while also decreasing the utilization of the senior residents (–24.71%).4 This is a very inexpensive solution to improve the system's

The Effect Of Inverse Square Law On A Beam Of X Ray Photons
Experiment 1
Introduction:
The aim of this experiment is to investigate the effect of the inverse square law on a beam of x–ray photons. The inverse square law states that the
intensity of an x–ray beam is inversely proportional to the square of the distance (Ball, J.L., Moore, A.D. and Turner, S., 2008). Similar triangles
(Appendix A– Image 1) are a proof of the inverse square law as it shows that if the distance from the beam is doubled, the intensity falls to one–quarter
of its original value. If it is trebled the intensity falls to one–ninth and at four times the distance it is one–sixteenth its value, etc (Holmes, K.,
Elkington, M. and Harris P., 2013). The formula used to calculate this is:
This law only applies if the radiation is from a point source, the radiation of the beam is homogenous (the photons must all have the same energy) and
if there is no attenuation between the source of radiation and the detector (Holmes, K., Elkington, M. and Harris P., 2013). However, thex–ray beam
cannot satisfy these three conditions of the inverse square law. This is because the x–rays produced are not emitted from a true point source as the
focal spot has a finite size. They are not emitted equally in all directions as the anode heel effect causes the intensity to vary across the beam and the
absorption and scattering of the x–ray beam occur as it passes through the air (Graham, D., Cloke, P. and Vosper, M., 2012). Despite this, the inverse
square law can still be applied

X–rays were discovered in 1895 when Wilhelm Conrad RГ¶entgen was doing some experiments with electron beams in a gas discharge tube and
observed a glow in one of his fluorescent screens whenever the electron beam was on.
It was a fact that fluorescent material usually glowed in reaction to magnetic radiation but the gas discharge tube was surrounded by heavy black
cardboard which was assumed by Roentgen to block most of the radiation. Confused and curious, Roentgen then put several objects between the tube

The denser areas are shown as white while the soft areas appear dark in the film but sometimes some organs may block x–rays from showing broken
or cracked bones and for this reason CAT (Computer Axial Tomography) was invented. Firstly, the person requiring the scan is put inside of a scanner,
which is a long tube–shaped machine and then x–rayed from all angles, after a computer puts all of the images together so that doctors can analyse
them. CAT are mainly used for head and brain injuries and appropriate shielded should be provided to cover the areas not being x–rayed.
At the dentist the same principle applies, x–ray film is put in one side of the teeth and x–rays are shot through the jaw, metal is more absorbent than
teeth and bones so any filling on the teeth would appear lighter in the x–ray film. Fig. 2
Exposure limits exist to prevent exposure and limit chronic exposure to "acceptable" levels because in fact there is no safe level of exposure as there is
always a small probability of exposure being the cause of some ailments, like cancer. It is then recommended to keep levels of exposure "as low as
reasonable achievable" (ALARA).
A person can safely get up to 300 simple x–rays a year or 5 CAT (Computed Axial Tomography) scans and the risk of developing cancer would only
increase by 1% as in most cases the cells that get damaged due to radiation die prematurely. The amount of cell damage from an x–ray is many times
less than

Using X–rays for medical imaging is one of the most useful pieces of medical technology available when trying to determine and locate, the type and
severity of a particular injury. X–rays are a form of electromagnetic radiation similar to visible light. However, unlike visible light x–rays can pass
through most objects, including the body (NIBIB, n.d). The radiation hits a detector on the other side of the patient and the image produced is a
shadowed representation of the tissues and structures in the body (NIBIB, n.d). However, due to the type of radiation being superimposed over the
body it is worrying knowing that this form of radiation can, in some cases, cause some very life threatening mutations. The term used to describe the

A translocation is when segments in chromosomes, and the genes they contain, change location. This translocation can occur a segment of the
chromosome breaking off and re–joining at another location (Cancer quest). The ionizing radiation can cause cells to die, but sometimes it can lead to
cancer later on. The amount of damage caused in the cell is related to the dose, frequency, a position on the body in which thex–ray is taking place
determines the extenet to which thesse mutations can occur. The damage can take place in a matter of seconds or it can take years to develop.

How X-Rays Interact With Tissue
There are two major ways in which X–rays interact with tissue. The first is the photoelectric effect, where a photon uses all of its energy to eject an
electron from an atom; that while the electron moves around and ionizes neighboring atoms, there are no scatter photons. The second major effect is
the Compton scatter, where a photon hits an atom and ionizes an electron but does not use all of its energy. The photon then scatters in a different
direction with slightly less energy, and the free electron does damage to the body. Scattered photons can travel back towards theX–ray tube, pass
through the patient and hit the detector from any odd angle, or scatter again within the patient. Every time a photon ejects an electron (ionizes an
atom), it creates free radicals that can damage DNA in the ... Show more content on Helpwriting.net ...
Both of these effects result in decreasing energy deposition from the skin to the back of the patient. In other words, much of the dose is deposited near
the skin. This is why the deterministic effects that are a large worry for doctors relate to skin injuries. Larger patients, who require higher doses to
penetrate through the larger body parts, are at higher risk of skin injuries. Therefore, it is very important to understand the intensity of X–rays to avoid
serious consequences.
Below is an object irradiated by many X–rays, with their intensity measured with a detector. The X–rays are passing through an object, and are strongly
absorbed so that their intensity is low, while other X–rays are passing through less of the object, and are less strongly absorbed. This makes their
intensity much stronger and higher. This intensity is measured and recorded at the center of the detector. In an effective manner, the object creates a
shadow of the X–rays, and from that, its basic dimensions can be

* Radiotherapy – used to treat cancer.
Ultrasound relies on high frequency sounds to image the body. As stated above, ultrasound are produced by an ultrasound transducer. To produce
ultrasound, a piezoelectric crystal has an alternating current applied across it, this causes the crystal to vibrate at a high speed and to produce
ultrasound as it converts electrical energy to mechanical energy in sound waves. This sound wave bounces off the object being scanned. This sound
triggers the piezoelectric crystal and has its affects reversed. By measuring the time taken to send and receive the sound the computer can produce
images. Ultrasound poses no health risks while x rays give off varying degrees of radiation. Exposure to radiation can have long term health although
the rates are very low. There are many different usages for ultrasound. The most common is for * pregnancy scans * examine the heart to identify
abnormal structures * measure blood flow through the hearts and major blood vessels * examine kidneys blood flow * identify kidney stones * detect

What is a Radiologist? A Radiologist is a specialized medical doctor who has had specific postgraduate training in performing and interpreting
diagnostic imaging test and treatments that involve the use of X– Rays, ultrasound, and magnetic resonance imaging equipment (InsideRadiology)
A Radiologist has a very hard job. This essay will talk about the basic job responsibilities, required steps necessary to secure employment, The average
salary/ statistics, interesting facts, and information of what a person in this field knows/ does.
The basic job responsibilities. Radiologists are trained to assist other doctors and specialists to treat their patients by making a diagnosis and providing
treatment using medical imaging. Radiologists have the medical knowledge to understand and explain medical problems or symptoms through the
images or pictures that are taken of various parts of the inside of the body (InsideRadiology)
Radiologists have many career paths they can go down. The list being from Fluoroscopy, Ultrasound, CT, MRI, PET, and Nuclear Imaging:
Fluoroscopy is the a study of moving body structures––similar to an X–ray "movie." A continuous X–ray beam is passed through the body part being
examined. The beam is transmitted to a TV–like monitor so that the body part and its motion can be seen in detail.
Ultrasound– is a medical ultrasonography used to visualize soft tissue structures in the body.
