3. Influence of the human body caused
by the radiation
● Higher than 100 rems have nausea,
vomiting, a headache.
● A white blood cell loses it in higher than
300 rems, and a platelet decreases.
● Half people die in higher than 450 rems.
● Higher than 800 rems are fatal injuries.

4. Atom bomb of Hiroshima and
Nagasaki
● Many people died within ten days from 7
after the atom bomb explosion.
● They did a severe burn in the whole body.
● They also did severe diarrhea, and blood
flowed from the gums.
● The survivor suffered from a cataract and
leukemia, a cancer.

5. Accident of three mile island
● The cooling loss of the nuclear reactor
lasted 16 hours.
● Radioactive gas was scattered in the air.
● 140,000 people evacuated from the area.
● It spent much money and time for the
convergence of the accident, but none of
the injured people appeared.
● Level 5

6. Nuclear plant accident of Chernobyl
● Level 7
● The number of the estimated total death is
16,000 people.
● It exploded without nuclear reaction being
stopped.
● 50 tons of nuclear fuel evaporated and
were released in the air.
● The radioactivity polluted a large area and
was prohibited from an entrance.

7. Medical care of the radiation
● The radiation has a good influence for the
human body if we take appropriate
quantity.
● It is used for the X-ray examination of the
stomach.
● The bone marrow transplantation helps
the supply of the white blood cell.
● The radiology is more unripe.

8. My conclusion
● The person caused the mistake caused by
the radiation many times.
● If we made use of a lesson well and
entered, we should have been able to
prevent the nuclear plant accident of
Fukushima.
● The world stops once and must think
about atomic energy.
● We must build it in oneself in the better
future.
