Fission Power Produces Unstable Nuclides Which Have Varying Half-Lives β\beta Emission with a Half-Life of 30

Question 14

Multiple Choice

Fission power produces unstable nuclides which have varying half-lives. One common product is cesium, with several different nuclides being produced. One nuclide that is problematic is 137Cs which decays by β\beta emission with a half-life of 30.2 years. How many years will it take for 1.5 kg of 137Cs to decompose to only 12 g of 137Cs?(If needed, use the following equation:  Fission power produces unstable nuclides which have varying half-lives.
