The half-life of cesium-137 is 30 years. Suppose we have 200 mg sample. How much of the sample remains after 60 years? [Hint: Let m(t) be the mass remaining from an initial mass mo of the radioactive substance after time t. Then m(t) moek for some decay constant k. The half-life is the time period for the radioactive substance decays to the exact half of oritinal substance amount. ]
