Radiation effects

  1. 1. Radiation Effects s1180033 Takahiro Hidano
  2. 2. IntroductionThe meltdown of the Fukushima nuclearpower generation that happened in Japanbrings damage in the neighboring areas.Now, Many people take a long period as arequest from the government and, includingan internal A-bomb victim, arerecommended an investigation of theinfluence of the radiation.
  3. 3. What is a Radiation?Radiation ・・・ The radiation is the grains such asX-ray, γ-ray and an α-ray, βray, the neutron raywhich ionized from radiation material. Electronic Wave Grain ● x-ray ● Electron beam ● γ-ray ● Proton beam(α-ray,β-ray) ● Electric wave ● Neutron beam ● Ultraviolet ray ● Infrared ray and more ● Visible ray
  4. 4. Harmful or Harmless? Harmful Harmless ● Ultraviolet ray ● Electric wave ● x-ray ● Infrared ray ● γ-ray ● Electron beam ● Visible ray (for eye) ● Neutron beam ● Proton beamBut, there is the radiation used for treatment in a harmfulradiation.
  5. 5. RadioisotopeRadioisotope・・・It is provided by nuclear fission andhave radioactivity.Radioisotope Time of Hale-lifeIodine131 8 daysIodine133 21 hoursCesium134 2 yearsCesium136 13 daysCesium137 30 yearsPlutonium238 88 yearsStrontium89 50 daysStrontium90 29 years
  6. 6. Cesium-137CharacteristicHalf-life ・・・ 29yearsAccumulation part・・・ MusclePrevention・・・ Reduce exposure of  the skin.Stimulant food ・・・Dairy products and Drinking 
  7. 7. Iodine-131CharacteristicHalf-life ・・・ 8daysAccumulation part・・・ Thyroid glandPrevention・・・ Taking iodine agentStimulant food ・・・ Dairy products
  8. 8. ConclusionThere is the harmless thing for the humanbody in the thing classified in a radiation.However, it is necessary to learn prophylaxissuitable for each because it is harmful to thehuman body including cesium-137 andiodine-131 released mainly by the nuclearpower plant.
