3. Dangerousness of Nuclear Power Plant
・Radial ray from nuclear power plant is very dangerous.
・170,000 people that are within 12miles from nuclear power plant
have to escape.
・People that are within 20miles from nuclear power plant have to
close window and not go out.

4. Type of radial ray
・Non-ionizing radiation
Non-ionizing radiation is used to cook food, send e-mail
address. Non-ionizing radiation is not harmful for people.
・Ionizing radiation
Ionizing radiation is harmful for people.
Ionizing radiation cause cancer and break chemical bound.

5. Example of two radial ray
・Non-ionizing radiation
infrared radiation, radio waves, cellphone radiation .
・Ionizing radiation
X-rays, gamma rays, alpha or beta particles.

6. Adverse affect of people to Ionizing
radiation
・Ionizing radiation cause cancer
・Ionizing radiation cause retching and fatigue.
・Ionizing radiation cause fallen hair
・For the last time ionizing radiation cause death.

7. Dangerousness of Nuclear Bomb
・X -rays and gamma rays are vented when nuclear bomb.
X-rays and gamma rays are Ionizing radiation.
Ionizing radiation cause cancer and death.
Ionizing radiation is dangerous.
・In 1945, Nuclear bomb fall down in Hiroshima. Many people dead
by nuclear bomb in Hiroshima.

8. Conclusion
There are two types for radiation. Non-ionizing radiation is not
harmful for people. people can use this. Ionizing radiation is
harmful for people but, Ionizing radiation is used by people
such as X-ray. However People cause cancer when people
bask many ionizing radiation. Radial ray is ionizing radiation.
In conclusion, Radial ray is harmful for people.
