The document discusses the effects of radiation on health from the Fukushima Daiichi nuclear disaster. It explains that there are two types of radiation: non-ionizing and ionizing. Ionizing radiation is more dangerous and can cause cancer. Exposure to radiation can initially cause nausea, fatigue and vomiting, and higher exposures may lead to hair loss, diarrhea, destruction of the intestinal lining, and eventually death. Cesium-137 and iodine-131 are particularly dangerous isotopes released during nuclear accidents. The document concludes by noting the sievert measurement of radiation dose and the types of sickness that different doses can cause.

1. How does the radiation effects
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
