your health?

2. Beginning of this presentation
● The Fukushima nuclear plants had broken
because of the Tohoku earthquake.
● So the nuclear plants release a massive dose of
radiation at that time.
● Now, the brave pretty people, the nuclear
engineers, the Tokyo electric power's workers, the
Self-Defense Forces of Japan, and so on, are
fighting against the nuclear plants.

3. Do you know the radiation effects?
● I didn't know detailed information about the
radiation.
● I knew the radiation may effects my health.
● We have to know about the radiation for ourself in
the future.
● So I write this presentation because you know
about the radiation and think about the fighting
people in the nuclear plants when you read it.

4. What is the radiation?
● All radiation is not dangerous.
● There are two types of radiation.
● Non-ionizing radiation
● Non-ionizing radiation includes radio wave and is
used by a microwave oven, so it is said there is
not big dangerous points in this radiation.
● ionizing radiation.
● Ionizing radiation is much more dangerous.
Because it can cause canser.

5. The ionizing radiation effects
● If you is exposed it, you are looked the initial
symptoms.
● First signs
○ nausea, fatigue, vomiting, and so on.
● Second signs
○ hair loss, diarrhea,
● Third signs (If you are heavier exposure)
○ destruction of the intestinal lining. dehydration
● Finally
It cause your death

6. The Fukushima nuclear plants
accidents and a nuclear bomb
● The Fukushima nuclear plants accidents and a nuclear
bomb are like that they can produce two type of radiation.
● If a nuclear explosion happens, many people are died
around the center of the nuclear explosion like the atomic
bombing in Hiroshima.
● And, the explosion prodece ash clouds having ceisium-137
and iodine-131.
● It is difficulty the clouds are carried away by wind and it,
so we need to skin foods and something to drink in the large
extent.

7. Cesium-137 and iodine-131 dangers
Iodine-131
● When you absorb many iodine-131, you may
have swellings.
● It is dengerous for children because it damages
cells, and children can be more damaged than
adults.
Cesium-137
● It acts like potassium and it is absorbed into the
body via foods, water, tissues, and so on.
● It has long life and is more serious than Iodine-
131.

8. Finally, How many radiational do they
cause sicks?
● The radiational risk is mesured in sieverts.
● When you adsorbed the radiational of
○ 500 microsieverts
■ nausea and fatigue
○ 750 microsieverts
■ hair loss
○ 1 milion microsievelts
■ hemorrhage
○ 4 million microseivelts
■ Death
