Strontium-90 is a radioactive waste product from nuclear reactors. It has a half-life of 29 years. How many years will it take for a quantity of strontium-90 to decay to 1/16 of its original mass?
It will take 29 years to decay to ½ its original mass; another 29 years to decay to ¼; another 29 years to ⅛; and another 29 years to 1/16.
29 + 29 + 29 + 29 = 116 years
a. You have 180 g of a radioactive substance. It has a half-life of 265 years. After 1,325 years, what mass remains?
