Nuclear radiation health_effects_article_2

  1. 1. Nuclear Radiation & Health Effects Article # 2 s1180198 Yuki Matsumoto
  2. 2. RadiationEffects on Humans 2011 March 11 , Fukushima  Nuclear power plant wasdamaged in Japan. Also radiation  became diffuse wide range. So I want to consider about this topic.
  3. 3. Effects of Radiation Exposure onHuman Health1.The unit used to measure radiation dosage is the "rem".2.The total dose of rems determines how much harm a person suffers.  Although a dose of just 25 rems causes some detectable changes inblood, doses to near 100 rems usually have no immediate harmfuleffects.   -nausea  -vomiting  -headache  -some loss of white blood cells
  4. 4. Major Radiation Exposure in Real Life Events1.Hiroshima and NagasakiMany people at Hiroshima and Nagasaki died not directly from theactual explosion, but from the radiation released as a result of theexplosion. It is said that at Hiroshima and Nagasaki, the few surviving doctorsobserved symptoms of radiation sickness for the first time. The survivors have suffered physically from cataracts, leukemia andother cancers, malformed offspring, and premature aging, and alsoemotionally, from social discrimination.
  5. 5. 2.Three Mile Island Radioactive gas was released into the atmosphere. And an estimated140,000 people were evacuated from the area. The reactor was a total loss and the cleanup required years of repairand hundreds of millions of dollars. No one was reported injured and the little radiation that leaked outwas quickly dispersed. Although this accident did cost lots of money and time, no one washurt.
  6. 6. 2.ChernobylThe accident at Chernobyl was the result of a fatal combination ofignorance and complacency. The explosion was chemical, driven by gases and steam generated bythe core runaway, not by nuclear reactions. About 50 tons of nuclear fuel evaporated and were released by theexplosion into the atmosphere. Still today, people are dying from the radiation caused by theChernobyl accident.It is said that the estimated total number of deaths will be 16,000.
  7. 7. Medical TreatmentThere is currently no effective medical treatment available forpotentially fatal radiation doses. Treatment for the ones that can be saved includes blood transfusionsand bone-marrow transplants. Bone marrow transplants rejuvenate the supply of white blood cellswhich was affected by the radiation.
  8. 8. ConclusionI learned about some nuclear plant accidents in this topic. Effect of radiation exposure on human health is different bynuclear plant accidents. I surprised that Thee Mile Island accidents is no one was hurt.
