This document discusses the effects of nuclear radiation on the body. It defines nuclear radiation as particle beams such as alpha rays, beta rays, gamma rays, and neutron rays. It notes that different types of nuclear radiation have varying abilities to penetrate materials. While nuclear radiation can have negative effects, it also describes positive medical uses of radiation including cancer treatment, food sterilization, and medical imaging. The document emphasizes that nuclear radiation comes with both risks and benefits, and should be used carefully.

• What is Nuclear Radiation?
• Effects to our body

3. What is Nuclear Radiation?
Nuclear Radiation means particle beam
such as alpha ray, beta ray, gamma ray, and
neutron ray.
These nuclear radiation can’t be seen from
naked eyes.
We use some particular equipment to
measure nuclear radiation.

4. What is Nuclear Radiation?
As shown in previous slide, there different
types of nuclear radiation.
Alpha ray can’t through even a piece of
paper.
Beta ray can through a piece of paper, but it
can’t through an aluminum plate.

5. What is Nuclear Radiation?
Gamma ray are hard, it can through less
than 50cm cement.
Neutron ray are most hard radiation, it can’t
through only hydrogenic atom.

6. Effects to our body
Today, we use nuclear radiation in many
way.
Nuclear radiation have not only negative
effects such as atomic weapon, but also
positive effects.

7. Effects to our body
Here lists positive effects of nuclear
radiation.
Medical care : Radiation can use to
cancer care.
Food : Radiation can use to sterilization.
Examination : We use X-ray to scan our
body or baggage at airports.

8. Nuclear radiation have some types of
radiation.
Nuclear radiation have not only negative
effects but also positive effects. We can use
nuclear radiation many ways and we must
use it carefully.
