2. RadiationEffects on Humans
2011 March 11 , Fukushima Nuclear power plant was
damaged in Japan. Also radiation became diffuse wide range.
So I want to consider about this topic.

3. Effects of Radiation Exposure on
Human Health
1.The unit used to measure radiation dosage is the "rem".
2.The total dose of rems determines how much harm a person suffers.
Although a dose of just 25 rems causes some detectable changes in
blood, doses to near 100 rems usually have no immediate harmful
effects.
-nausea
-vomiting
-headache
-some loss of white blood cells

4. Major Radiation Exposure in Real Life Events
1.Hiroshima and Nagasaki
Many people at Hiroshima and Nagasaki died not directly from the
actual explosion, but from the radiation released as a result of the
explosion.
It is said that at Hiroshima and Nagasaki, the few surviving doctors
observed symptoms of radiation sickness for the first time.
The survivors have suffered physically from cataracts, leukemia and
other cancers, malformed offspring, and premature aging, and also
emotionally, from social discrimination.

5. 2.Three Mile Island
Radioactive gas was released into the atmosphere. And an estimated
140,000 people were evacuated from the area.
The reactor was a total loss and the cleanup required years of repair
and hundreds of millions of dollars.
No one was reported injured and the little radiation that leaked out
was quickly dispersed.
Although this accident did cost lots of money and time, no one was
hurt.

6. 2.Chernobyl
The accident at Chernobyl was the result of a fatal combination of
ignorance and complacency.
The explosion was chemical, driven by gases and steam generated by
the core runaway, not by nuclear reactions.
About 50 tons of nuclear fuel evaporated and were released by the
explosion into the atmosphere.
Still today, people are dying from the radiation caused by the
Chernobyl accident.
It is said that the estimated total number of deaths will be 16,000.

7. Medical Treatment
There is currently no effective medical treatment available for
potentially fatal radiation doses.
Treatment for the ones that can be saved includes blood transfusions
and bone-marrow transplants.
Bone marrow transplants rejuvenate the supply of white blood cells
which was affected by the radiation.

8. Conclusion
I learned about some nuclear plant accidents in this topic.
Effect of radiation exposure on human health is different by
nuclear plant accidents.
I surprised that Thee Mile Island accidents is no one was hurt.
