2. INTRODUCTION
The particles that are released from nucleus during
radioactive decay, energy released as high-speed charged
particles or electromagnetic waves. It has 3 types.
1)Alpha Rays 2)Beta rays
3)Gamma Rays

This hypothesis was disproved on the 26th-27th of
February, when his experiment "failed" because it was
overcast in Paris.
Becquerel decided to develop his photographic plates
and to his surprise, the images were strong and clear,
proving that the uranium emitted radiation without an external
source of energy such as the sun.

Becquerel had discovered radioactivity.
Becquerel used an apparatus to show that the radiation
he discovered could not be x-rays. X-rays are neutral
and cannot be bent in a magnetic field while new
radiation was bent by the magnetic field so that the
radiation must be charged and different than x-rays.

When different radioactive substances were put in the
magnetic field, they deflected in different directions or
not at all, showing that there were three classes of
radioactivity: negative, positive, and electrically neutral.
The term radioactivity was actually coined by Marie
Curie.

The Curies extracted uranium from ore and found that
the leftover ore showed more activity than the pure
uranium.
They concluded that the ore contained other
radioactive elements. This led to the discoveries of the
elements polonium and radium.

Ernest Rutherford, who did many experiments studying
the properties of radioactive decay, named these alpha,
beta, and gamma particles, and classified them by their
ability to penetrate matter.

8. WHY NUCLEAR
RADIATION USE FOR
X-RAY
X-rays pass through the soft tissue, such as intestines,
muscles, and blood vessels these tissues are difficult to
visualize on a standard X-ray, unless a contrast agent is
used. This allows the tissue to be seen more clearly.
Nuclear imaging enables visualization of organ and tissue
structure as well as function.

9. WHAT ARE THE
BENEFITS OF
NUCLEAR IMAGING?
Nuclear imaging is a safe, painless, and cost-effective way
of gathering information that may otherwise be unavailable
or require a more expensive and risky diagnostic test.

10. WHAT ARE THE SIDE
EFFECTS OF NUCLEAR
RADIATION?
Symptoms of ARS These symptoms include loss of
appetite, fatigue, fever, nausea, vomiting, diarrhea, and
possibly even seizures and coma. This seriously ill stage
may last from a few hours up to several months. People
who receive a high radiation dose also can have skin
damage.

11. IF RADIATION IS BAD FOR
HUMANS, IS THERE AN
ALTERNATIVE WAY TO TAKE
AN X-RAY OR TECHNOLOGY
BEING CREATED TO DO SO?
Most radiation is completely harmless to humans. Without
heat and light, you’d find it difficult to survive-rays,
particularly modern ones, are very low risk, given their
intensity and the frequency of exposure. There isn’t much
incentive to seek alternatives. There are other imaging
modalities, such as magnetic resonance imaging, positron
emission tomography, etc. Each carries its own risks, and
is good at visualizing different things — and none as
cheap and quick as an X-ray.

12. IS NUCLEAR RADIATION
HARMFUL?
At high doses, ionizing radiation can cause immediate
damage to a person's body, including, at very high doses,
radiation sickness and death. At lower doses, ionizing
radiation can cause health effects such as cardiovascular
disease and cataracts, as well as cancer

13. WHAT TYPE OF
RADIATION IS
NUCLEAR RADIATION?
Radiation particularly associated with nuclear medicine
and the use of nuclear energy, along with X-rays, is
'ionizing' radiation, which means that the radiation has
sufficient energy to interact with matter, especially the
human body, and produce ions, i.e. it can eject an electron
from an atom

14. WHY USE NUCLEAR
RADIATION?
Nuclear medicine procedures help detect and treat
diseases by using a small amount of radioactive material,
called a radiopharmaceutical. Some radiopharmaceuticals
are used with imaging equipment to detect diseases.
Radiopharmaceuticals can also be placed inside the body
near a cancerous tumor to shrink or destroy it.
