2. Danger of radiation As for the radiation, it is within 20 miles to be dangerous. People within 12 miles were able to take shelter in the first power plant in Fukushima. It is warned that the ventilation system is ended when remaining within doors moreover.
3. About the radiation All the radiations are not dangerous. There are two kinds of radiations. It is ionizing and nonionizing.
4. Nonionizing radiation The nonionizing radiation is used for infrared rays, the electric wave, and the cellular phone. Moreover, we are using the radiation to cook food with the microwave oven. Because these do not destroy the chemical linkage, it is safe.
5. Ionizing radiation The ionizing radiation becomes causes of cancer. Therefore, it is very dangerous. It is used for x line and gamma rays.
6. Symptom If we can expose it to the radiation, we become cancer. We have nausea, tiredness, and vomiting first. Afterwards, it becomes depilation and diarrhea. We have the likelihood of dying if exposed to the radiation for a long time.
7. Nuclear bomb A nuclear bomb is dangerous. A nuclear bomb generates a large amount of x lines and gamma rays due to the explosion. Consequently, we die when we bathe in a large amount of radiation.
