2. 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.
3. Human health effects
25rem almost no effect
100rem nausea, vomiting, headache
300rem hair loss, organ damage
4. 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
5. 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

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.
6. 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.
7. 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.
8. 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.
