Nuclear radiation effects

  1. 1. How does the radiation effects your health? s1180212 Taisuke Kasai
  2. 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 powers workers, the Self-Defense Forces of Japan, and so on, are fighting against the nuclear plants.
  3. 3. Do you know the radiation effects?● I didnt 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. 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. 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. 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. 7. Cesium-137 and iodine-131 dangersIodine-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. 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
