The document discusses sources of background radiation that people are exposed to on a daily basis. It states that the largest sources of radiation exposure are cosmic rays, radon gas inhaled from the air, radioactive potassium-40 from food, and gamma rays from rocks and building materials. The document also notes that while radiation can potentially damage DNA and cause health issues, most people live without harm from the levels of background radiation they experience.
Radiation
Radiation comes in different types, with ionizing radiation being the most harmful. Ionizing radiation can damage cells by pulling electrons out of the body, and exposure to more than 2 Sieverts at once can cause death. However, we are exposed to low levels of ionizing radiation constantly from natural sources like bananas and soil. While places like Hiroshima were highly radioactive after nuclear attacks, radiation levels there have decreased to normal background levels of around 0.3 micro Sieverts, similar to many other locations on Earth. Air travel exposes passengers to higher radiation of around 3 micro Sieverts per hour due to higher altitudes.
Basics Of Radiation
The document discusses different types of radiation including ionizing radiation like alpha, beta, and gamma rays. It describes their properties and how they are emitted from radioactive atoms. It also covers radiation units, health effects of radiation exposure, and common sources of radiation including medical uses, consumer products, space exploration, and nuclear power. Radiation is used for a variety of applications but also poses health risks if exposure limits are exceeded.
Radiation
Radiation can be ionizing or non-ionizing and comes from natural and man-made sources. Ionizing radiation like alpha, beta, gamma, and x-rays can damage biological tissues by ionizing atoms. Exposure to high doses can cause acute effects while long-term low doses are linked to increased cancer risks. Radiation protection methods aim to reduce exposure time near sources and increase distance and shielding between people and radiation. Exposure is monitored using personal dosimeters and survey meters to track doses and identify sources.
Radioactive Community medicine
This document summarizes different types of radiation sources and their effects. It discusses natural sources like cosmic rays and radioactive elements within the body, as well as man-made medical sources like X-rays. It also covers the units used to measure radiation, the biological effects of both ionizing radiation like X-rays and gamma rays, as well as non-ionizing radiation. Finally, it provides information on radiation protection standards and the biological response and potential health effects from different levels of radiation exposure.
Ionising radiation
Ionizing radiation comes from the decay of unstable atoms and includes alpha particles, beta particles, neutrons, gamma rays, and x-rays. It is measured in units of activity, absorbed dose, and dose equivalent, and can be used for power generation, research, medical procedures, and other applications. Prolonged or repeated exposure to ionizing radiation can lead to both acute and long-term health effects like cellular damage, radiation sickness, and increased cancer risk. Methods of radiation protection include containment, shielding, increasing distance, and limiting exposure time and frequency.
Dangerousness of Nuclear Radiation
Nuclear radiation consists of particle beams that can harm human cells and potentially cause cancer. Exposure to nuclear radiation occurs internally from ingesting radiological material or externally from sources like X-rays, with internal exposure posing a greater risk. Several major nuclear accidents over exposure to radiation have occurred, such as at Chernobyl, Three Mile Island, and Fukushima, demonstrating the dangers of mishandling nuclear materials and radiation.
Non ionising radiation
Non-ionizing radiation refers to electromagnetic radiation that does not have enough energy to ionize atoms or molecules. It includes optical radiation such as ultraviolet, visible, and infrared light, as well as radiofrequency/microwave radiation. Sources include natural sources like sunlight as well as man-made sources used in communications, industrial, scientific, and medical applications. Biological effects depend on the type of non-ionizing radiation and can include skin damage, eye damage, heating tissues, and are being studied for long-term health effects.

2.8 understanding radiation
Alpha, beta, and gamma radiation differ in their properties and penetrating abilities.
Alpha radiation consists of helium nuclei that are highly ionizing but cannot penetrate the skin. Beta radiation is made of electrons that are moderately ionizing and penetrating, able to pass through a few mm of metal. Gamma radiation is electromagnetic radiation that is only weakly ionizing but can pass through several cm of lead.
Alpha radiation is used in smoke detectors. Beta radiation monitors thickness of paper production. Gamma radiation sterilizes food and treats cancer.
Radiation
Radiation comes in many forms, both natural and man-made. While some types like ionizing radiation can be harmful if exposed in high doses over long periods, radiation is also all around us in everyday life from sources like wifi, microwaves, visible light, and more. The document discusses the different types of radiation like alpha, beta, gamma, x-rays, and their varying abilities to penetrate materials. Overall, radiation is a natural phenomenon and in moderation the risks are quite low compared to other common causes of death.
Understanding Ionising Radiation
Ionising radiation comes from radioactive materials and can damage human cells. There are three main types: alpha particles, beta particles, and gamma rays. Alpha particles are the largest but easiest to stop, while gamma rays are smallest but hardest to stop. Radioactive decay occurs as unstable atoms emit radiation and become more stable. Each type of decay changes the atom in a different way. Ionising radiation is dangerous as it can damage DNA in human cells and lead to cancer or genetic defects.
Ultraviolet Presentation
Ultraviolet radiation has wavelengths between 400nm and 15nm, falling between violet light and X-rays on the electromagnetic spectrum. It is divided into UV-A from 400-320nm, UV-B from 320-280nm, and UV-C from 280-100nm, with shorter wavelengths being more energetic and potentially dangerous. UV-A passes through glass while UV-B induces vitamin D production but can cause harm from overexposure.
Gamma rays
Gamma rays are the most energetic form of electromagnetic radiation, with very short wavelengths. They are produced during radioactive decay when the nucleus emits high-energy photons to rid itself of excess energy. Paul Villard discovered gamma radiation in 1900 while studying radiation emitted from radium. Gamma rays cause damage at the cellular level and can induce cancer or genetic damage from low levels of exposure or acute tissue damage at high levels.
Radiation safety and hazards, Control
Radiation can be categorized as ionizing or non-ionizing. Ionizing radiation includes alpha, beta, gamma, and neutron radiation, which can be harmful in high doses. Natural background radiation comes from cosmic rays, terrestrial sources like uranium and thorium in soil, and inhaling or ingesting naturally occurring radioactive materials. The largest sources of natural background radiation are radon inhalation and terrestrial sources. Artificial sources include residual radiation from past atmospheric nuclear weapons testing. The document discusses the various types of radiation and their sources to provide an understanding of radiation hazards, evaluation, and safety.
Ionizing Radiation
Deep Shah presented on ionizing radiation. Ionizing radiation has enough energy to remove electrons from atoms, ionizing them. There are three main types of radioactive decay - alpha, beta, and gamma. Alpha particles emit helium nuclei, beta particles emit electrons or positrons, and gamma rays are electromagnetic radiation. X-rays are a form of electromagnetic radiation similar to gamma rays but are emitted by electrons rather than the nucleus. While ionizing radiation can be hazardous, it has important medical uses such as radiation therapy to treat cancer.
Gamma rays
Gamma rays are a type of electromagnetic radiation that are produced by radioactive decay and other high-energy processes. They have higher energy than X-rays and are ionizing radiation. Natural sources of gamma rays on Earth include naturally occurring radioactive elements and interactions between cosmic rays and the atmosphere. Gamma rays are also produced by astronomical processes involving high-energy electrons. They have frequencies above 10 exahertz and energies above 100 keV.
Basic radiation 061706
This document provides an overview of basic radiation concepts including:
1) It describes different types of radiation including alpha, beta, gamma, and neutron radiation and how they interact with matter.
2) It discusses radiation safety principles such as minimizing time, distance, and using shielding to reduce radiation exposure.
3) It explains why we need to measure radiation today including uses in medicine, industry, and to detect potential radiological threats from lost radioactive sources or radiological dispersion devices.
Radiation Effect
Radiation can be useful but also dangerous. There are two types - non-ionizing radiation like infrared that is generally safe, and ionizing radiation like X-rays that can cause cancer. Exposure to increasing amounts of radiation causes symptoms from nausea to hair loss to organ damage and eventually death. Nuclear bombs immediately kill many people with radiation, while nuclear plant accidents release radioactive particles that long-term can increase cancer rates. Radiation must be carefully managed to balance its benefits with ensuring public safety.
Gamma rays
Gamma rays are a type of electromagnetic radiation emitted from radioactive decay. They are high energy photons produced when the nucleus of an atom transitions from a high energy state to a lower energy state. Gamma rays were discovered in 1900 by Paul Villard and named by Ernest Rutherford in 1903. Natural sources of gamma rays on Earth include naturally occurring radioactive isotopes and interactions between cosmic rays and the atmosphere. Gamma rays can also be produced by astronomical processes involving high energy electrons. They typically have frequencies above 10 exahertz and energies above 100 keV.
sources of radiation
Radiation comes from natural and man-made sources. Naturally, radiation comes from cosmic rays, radioactive materials in the ground and air like radon, and internal radioactive elements. Man-made sources include medical uses of radiation in diagnostic imaging and cancer treatment, consumer products containing radioactive materials, nuclear power plants, and occupational exposures. The goal of studying radiation effects is to understand its impact on humans to improve safety in medical uses and effectiveness in cancer therapy.
Radiation hazards
Radiation is energy transmitted through space or matter in the form of waves or particles. It includes visible light, ultraviolet light from the sun, and radio/TV signals. Nuclear radiation comes from unstable atoms undergoing radioactive decay, emitting particles like alpha and beta or electromagnetic waves like gamma rays. Exposure to ionizing radiation can damage living tissue. Natural sources of radiation include cosmic rays, radioactive elements in the earth's crust like radon, and some food/drink. Medical procedures and occupational exposures also contribute. In materials, radiation can cause impurities from nuclear reactions, ionization by charged particles, and displacement of atoms from their normal positions in the crystal structure.
Physics Gamma Ray
Gamma rays are a form of electromagnetic radiation emitted from radioactive substances. They have the shortest wavelengths and highest frequencies of any type of electromagnetic wave. Gamma rays are produced during radioactive decay, electron-positron annihilation, and other nuclear processes. Some key applications of gamma rays include use in radiography, cancer treatment, food sterilization, and nuclear weapons.
Radiobiology3&4
The document discusses different types of electromagnetic radiation and particle radiation, including their properties and sources. It covers the electromagnetic spectrum, from radio waves to gamma rays. It also discusses ionizing radiation that can remove electrons from atoms, such as x-rays, gamma rays, alpha particles, and beta particles, and their ability to cause biological effects. Low levels of naturally occurring and man-made radioactive materials are present in our environment.
Radiation Safety
1) Ionizing radiation includes x-rays, gamma rays, alpha particles, beta particles, neutrons, and charged nuclei that are capable of producing ion pairs by interacting with matter.
2) Different types of ionizing radiation have varying penetration depths and biological impacts depending on their energy and linear energy transfer. Alpha particles can be stopped by paper but are very damaging if inside the body, while x-rays and gamma rays can penetrate further.
3) Radioactive materials decay from unstable to stable states and in the process may emit various combinations of ionizing radiation particles like alpha and beta particles as well as gamma rays. Decay chains occur when a parent decays to a daughter isotope that is also radioactive.
Radiation and it’s effect in human life
Radiation comes from natural and manmade sources and can be ionizing or non-ionizing. Natural sources include cosmic radiation from space, terrestrial radiation from the Earth's crust, and internal radiation from isotopes inside the human body. Manmade sources include X-rays, nuclear power, and wireless technologies. Radiation can damage human tissue depending on the amount, with effects including hair loss, reduced blood cell count, gastrointestinal issues, and increased cancer risk with higher exposures. Proper shielding, protective equipment, limiting exposure time, and monitoring with dosimeters can help reduce radiation risks.

The effect of nuclear radiation on the human
This document discusses the effects of nuclear radiation on the human body. It defines nuclear radiation and the different types, including alpha particles, beta particles, gamma rays, and neutrons. It explains how radiation is produced through nuclear decay, fission, or fusion and discusses the health impacts of different types of radiation depending on their size and energy. The document provides context on natural sources of radiation and appropriate safety standards to limit health risks from radiation exposure.
Radiation protection
A former Russian spy named Litvinenko died of radiation poisoning in the UK. Tests found high levels of polonium-210, a radioactive substance, in his urine. Experts said polonium-210 is dangerous if ingested or inhaled and can spread throughout the body and damage major organs. Litvinenko's death was described as unprecedented in the UK and he was apparently poisoned by radiation.
Radiation Basics
Radiation comes in different forms, including ionizing radiation which can damage DNA and cause cell mutations. Ionizing radiation is emitted during radioactive decay and comes from both natural and man-made sources. Exposure to ionizing radiation, even at low doses, increases cancer risks as it can cause unpredictable damage at the cellular level. Radioactive materials also bioaccumulate up food chains, increasing exposure risks for humans. Protecting against radiation exposure and limiting contamination of the environment are therefore important public health issues.

Learning more about radioactivity by AREVA - 2005 publication
Radioactivity comes from unstable atomic nuclei that spontaneously emit radiation. Some elements like uranium and radium are naturally radioactive, while other radioisotopes have been artificially produced. Radioactivity is measured using units like becquerel (disintegrations per second), gray (energy absorbed), and sievert (biological effects on exposure). Proper shielding, distance, and limiting exposure time can help protect against radiation.
Radiation
Radiation comes in many forms, both ionizing and non-ionizing. Ionizing radiation can damage molecules and DNA through chemical reactions. Many everyday items contain small amounts of natural radioactive elements like potassium-40, uranium, and thorium that produce ionizing radiation, such as bananas, Brazil nuts, granite, smoke detectors, watches, and cat litter. Exposure to radiation levels from these common sources is not a significant health risk.
INTRODUCTION_TO_RADIATION_SAFETY_ppt.pptx
This document provides an introduction to radiation safety. It defines radiation as energy emitted as particles or waves, and describes the electromagnetic spectrum. There are two types of radiation: non-ionizing and ionizing. Naturally occurring sources of radiation include bananas, the sun, and radioactive elements in the ground. Man-made sources include nuclear power plants, atomic bombs, medical equipment, and smoke detectors. Radiation contamination occurs when radioactive material is somewhere it shouldn't be. Exposure to radiation can increase cancer risks depending on the dose received. The Nigerian Nuclear Regulatory Authority regulates radiation exposure and safety in Nigeria.
Radioactive waste
Radioactive pollution occurs when radioactive materials are released into the environment unintentionally. It can come from natural sources like radon gas or cosmic rays, or from human activities involving nuclear materials. Radioactive pollution contaminates surfaces, air, water, and bodies. Exposure to ionizing radiation emitted by radioactive materials can damage DNA and increase cancer risks, especially for skin, bone marrow, and thyroid cells that divide rapidly. Past nuclear accidents in India have caused radioactive pollution. Proper disposal of nuclear waste and minimizing nuclear activities can help prevent further radioactive pollution.

Prevention methods center around reducing radioactive emissions, waste disposal, and minimizing unnecessary nuclear activities.
Radioactive-Pollution-ppt12.pptx
This document presents information on radioactive pollution. It defines radioactive pollution as the release of unwanted radioactive material into the environment. It discusses the types of radiation as ionizing (alpha, beta, gamma rays) and non-ionizing. Sources of radioactive pollution are outlined as natural (radioactive minerals, cosmic rays, radioisotopes) and anthropogenic (nuclear tests, reactors, waste). Effects on humans can range from mild irritation to cancer depending on exposure level and duration. Prevention methods include limiting nuclear activities, proper waste disposal, and minimizing radiation doses.
Lesson 4 Ionizing Radiation | The Harnessed Atom (2016)
The document provides information about different types of radiation, including ionizing and non-ionizing radiation. It discusses radioactive decay and half-life. It also addresses natural and human-made sources of radiation exposure and averages about 6 mSv of annual exposure for Americans. Radiation can potentially cause cell damage but low levels are generally harmless due to body's ability to repair itself.
Nuclear pollution
Nuclear pollution occurs when radioactive substances or radiation contaminate the environment. Major sources include nuclear power plants and nuclear weapons testing. Nuclear pollution can affect all life forms and potentially cause mutations, cancer, and death depending on radiation exposure levels. While nuclear power has benefits, it also produces hazardous nuclear waste and accidents can release radiation. Proper handling, storage, and containment of radioactive materials and waste is needed to control nuclear pollution and its severe health impacts.
Radiation Hazards
An elementary guide to radiation hazards: what you should worry about, what you shouldn't, and why.

Radiation can come from radioactive decay or machines and takes different forms. There are two types of radiation: non-ionizing and ionizing. Non-ionizing radiation has enough energy to move or vibrate atoms but not remove electrons, while ionizing radiation can remove electrons through ionization. Ionizing radiation is a health risk as it can damage tissue and DNA. There are different types of ionizing radiation - alpha particles, beta particles, gamma rays, and x-rays - which have different properties and penetration abilities. Elements can exist in stable or unstable, radioactive forms known as radionuclides.

Pharmacology of 5-hydroxytryptamine and Antagonist
5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.
