3. Unit of Measurement
The unit to measure amount of radiations is the rem usually. The total
of the rem represents that human how much is exposed radiations. In
addition, Many Japanese was received the rem at Hiroshima and
Nagasaki.

4. Effects of Radiation
Amount of the rem affect humans basically. Amount of the rem
depends gets an outbreak.
Doses of just 25 rem is that change blood of human a little.
Doses of 100 rem is that don't represent disease soon. First sign of
disease is the disease such as nausea, vomiting, headache and some
loss of white blood cell.
Doses of 300 rem is that cause hair loss. In addition, it affects intense
of human.
Basically, the human that receive dose of the rem more than above
doses will die.

5. Three Mile Island
Three Mile Island nuclear power plants have happened accident. The
reactor of the nuclear plant continued to stop for about 16 hours. In
addition, Radioactive gas was released into the around. Therefore,
about 140,000 people that live near the nuclear plants had to escape to
safe place. Stopping accident of the nuclear plant took for about a
month. So, stabilizing the nuclear plant need to use many costs.
However, no one was injured by this accident.

6. Chernobyl
The Chernobyl nuclear power plants in Rossiya have happened big
accident. The accident of the nuclear plant was more complex than
accident until then. About 50 tons of nuclear fuel were released into
the area by blast of the nuclear plant. Large area of Chernobyl was
contaminated by those radiations. In addition, Many people was died
by those radiations. Still today, the people that is affected by those
radiations is suffering.

7. Medical Treatment
Currently, there is no efficient medical treatment against radiation. In
fact, depend on the person that is received radiation. Therefore, the
doctor can not examine the person exactly. However, There is way to
help the person. It is blood transfusions and bone-marrow transplants.

8. Conclusion
Nuclear power plants have affected us continuously until now.
Because nuclear power plants can create much electricity, it is
necessary for us. However, nuclear power plants are the most worst
entity if big accident happens. Therefore, we have to think about
entity of nuclear power plants now.
