A. 24.87 years There is 100 mCi of Cs-137 and 300 mCi of Co-60. Calculate the time it will take for both isotopes to decay until their activities are equal. V B. 10.12 years C. 5.90 years That's Incorrect | Correct Answer:B D. 8.46 years Rationale: Use the decay function for both isotopes and set them equal to each other. (Cs-137 decay = Co-60 decay) Solve for t. = -at Ае
