Document Summary
Chernobyl, u. s. s. r (1986) had 10 to 20 times higher dose than the three mile accident. The effect of different doses of radiation on the human body after acute, whole body exposure: highly sensitive: breasts lungs, stomach, colon, moderate sensitive: brain, pancreas, low sensitive: skin, bone, spleen, kidney, gall bladder. Some scientist believe low levels are beneficial and may cure some cancer but can also cancer. Many cases prove this: first observed in 1910, uranium miners, medical treatments, children are more sensitive because they grow more rapidly. Determine where health effects occur in our body. Our organs cannot distinguish between the radioactive and non-radioactive form of element: radioactive iodine in thyroid (body cannot tell it is radioactive and absorb it regardless, calcium, strontium-90 and radium-226 accumulate in the bones. This is not good for our body. Yielded in breakdown of uranium in soil, rock, and water (more often in ground water).
