What a radiation?

● There are many types of radiation and each has a different nature.

● Exposure to radiation cause fire, cancer,

and when severe may die.The unit of radiation is used rem.

Human health effects

25rem almost no effect

100rem nausea, vomiting, headache

300rem hair loss, organ damage

Radiation effects in Hiroshima ● 14 year old boy in the case

1day high fever and nausea

2day The hospital in Hiroshima

9 day Start of hair missing. Reduce the amount of leukocytes.

17 day nose bleeds.

21 day Death

With radiation incident at Three Mile Island

Wednesday morning, confirming the primary radiation from the water in the Three Mile Island reactor. The main water supply system is damaged and water in houses containing radiation and gas leaks. Residents had to evacuate. Fortunately, the death toll from this incident, but was not injured. As a result, took a lot of time and money for repairs and cleaning of the radiation of a nuclear reactor.

With radiation incident at Chernobyl Chernobyl was the Soviet Union in the nuclear power plant in Chernobyl exploded. INES (International Nuclear Event Scale) are classified as Level 7. According to the worst level. This is the same as a nuclear power plant in Fukushima incident happened this year.

Number of deaths Have been announced number of deaths is 33 people who firefighters, operating personnel and other people. But appears to have been confirmed dead including a number of soldiers hit the handle of the accident. Also, because a lot of civilians exposed to radiation. If someone is sick and many cancers of white blood cells.

International Nuclear Event Scale

INES is a measure of the failure of a nuclear accident assessment. International Atomic Energy Agency (IAEA) and the Economic Cooperation and Development Nuclear Energy Agency bubble (OECD / NEA) has been formulated. Are operated on a trial basis in 1990, was carried out in the world officially in 1992. Are divided into seven stages in total, if applicable to level 7 of the most dangerous and out of the dead is not even funny. The main accident that "Chernobyl incident" and "Fukushima Daiichi Nuclear Power Station accident" is relevant to Level 7.

Conclusion

● There is no way for radiation therapy. So it is important to be careful as possible exposure to radiation.

● As shown in slide 3, so that could die and more than they receive 300rem. Soit is important to measure radiation prevention firm.
