This document discusses two types of radiation: non-ionizing and ionizing. Non-ionizing radiation such as infrared and radio waves is not harmful, while ionizing radiation like X-rays and gamma rays can break chemical bonds and cause cancer. Specifically, the radiation from Fukushima is in the form of radiocesium and radioiodine. Cesium is dangerous because it spreads throughout the body and contaminates food and water, while iodine is absorbed in the thyroid and can cause tumors, especially in children. The conclusion recommends increasing knowledge about dangerous radiation doses and continuing cleanup efforts in Fukushima.

2. Tow types of radiation
— Non-ionizing radiation is not harmful
(Infrared radiation, radio waves, cellphone
radiation and the radiation etc.)
— Ionizing is harmful (X-rays, gamma rays and
the alpha or beta etc.)

3. Non-ionizing
— It dose not break chemical bonds.
— It dose not have significant effects.
— It is not believed to cause cancer.

4. Ionizing radiation
— It is dangerous.
— It does break chemical bonds.
— It dose cause cancer.

5. Radiation In Fukusima
— Not emitting gammar or X-irradiation.
— Most of the radioactivity is in the form of
radiocesium and radioiodine.

6. What makes cesium dangerous?
— It is a salt goes everywhere in the body.
— It is absorbed into soft tissues, causing
sarcomas.
— It contaminates food, water and milk.
— It gets into the body when contaminate food
are ingested.

7. What makes iodine dangerous?
— Iodine is absorbed in the thyroid gland,
where it can cause tumors.
— It has a half-life of eight days and is most
dangerous to children.

8. Conclusion
— People should knowledge how much does of
radiation are dangerous.
— It is necessary to improve in Fukushima so
that doses of radiation should not increase
any further.
