It has been estimated that about 75 million people in the Ukraine and Byelorussia were exposed to an average of 0.4 rem of radiation as a result of the Chernobyl nuclear accident. Human exposure to radiation is often measured in rems (roentgen-quivalent man) or millirems (mrem). The cancer risk caused by exposure to radiation is thought to be approximately 1 fatal cancer per 8,000 person-rems of exposure (for example, this is like saying when 8000 people are exposed to 1 rem each, one person will die of cancer caused by this exposure). (a) How many extra cancer deaths might eventually be expected from this exposure?(b) If the normal probability of dying of cancer from all causes is 0.22 (that is, 22% of any population of people will die of cancer), how many cancer deaths would you normally expect among those 75 million people?
