بنام خدا مدیریت بحران در فجایع هسته ای Nuclear Power Plant in Chooz - France Accidents, Explosions, Natural Disasters Effects of nuclear radiation on Human body Unist and Conversion 1 gray (Gy) = 100 rad1 rad = 10 milligray (mGy)1 sievert (Sv) = 1,000 millisieverts (mSv) = 1,000,000 microsieverts (μSv)1 sievert = 100 rem1 becquerel (Bq) = 1 count per second (cps) 1 curie = 37,000,000,000 becquerel = 37 Gigabecquerels (GBq) For x-rays and gamma rays, 1 rad = 1 rem = 10 mSv For neutrons, 1 rad = 5 to 20 rem (depending on energy level) = 50-200 mSv For alpha radiation (helium-4 nuclei), 1 rad = 20 rem = 200 mSv Doses 10 μSv – The average radiation you received today 40 μSv – The radiation you receive by taking a flight from New York to L.A. 100 μSv – The radiation you receive during a dental x-ray 800 μSv – Total radiation dose at Three-Mile Island for the duration of the accident 3,000 μSv – Radiation dose from a mammogram 3,600 μSv – Average radiation a US citizen receives in a year from all sources 50,000 μSv – Maximum allowable yearly occupational dose (USA) 100,000 μSv – Lowest yearly dose likely linked to increased cancer risk 2,000,000 μSv – Severe radiation poisoning (sometimes fatal) Effects on Different Organs Disformed chromosomes of a human being who has received Gamma radiation in long period Natural Exposure
