Cesium-137 is a radioactive byproduct of the fission process. Much Cesium-137 was deposited in the Bikini Atoll (in the Southwestern Pacific Ocean) during atomic bomb tests of the 1940s. How many years will it take 128-grams of Cesium-137 to decay to only 4-grams of Cesium-137 if its half-life is 30 years?
