Radioactive cobalt-60 is used extensively in nuclear medicine as a x-ray source. It is made by a neutron capture reaction from the cobalt-59 and is B-emitter, B emission is accompanied by strong y radiation. If the half-life of Co-60 is 5.27 years: a. How long will it take for the Co-60 source to decrease to one-twelfth of its original amount? b. What percent of Co-60 source will remain after 1 year? Show the complete solution including the formula and write it in a paper
