Question asked by Filo student
After the fallout of radioactivity over Sweden from the nuclear power disaster in Chernobyl in 1986, the Swedish National Food Agency set a limit of 1500 Bq/kg for the allowed activity (from 137Cs) in meat from reindeer. Assuming that the entire Swedish population (approximately 9 million people) had eaten one 200 g portion of reindeer meat that year with the maximum allowed activity, how many people may be estimated to develop fatal cancer from this today? Hints: Assume full-body radiation and that the radiation is absorbed in the body. Use an average value for the electron energy from the 137Cs decay. Note: The result is an overestimate since the assumption of full-body irradiation overestimates the total dose.
