WebSolution: The number of atoms of iodine-131 can be determined using isotopic mass as below. NI-131 = mI-131 . NA / MI-131. The activity of the iodine-131 in curies can be determined using its decay constant: The iodine-131 has a half-life of 8.02 days (692928 sec), and therefore its decay constant is: Using this value for the decay constant, we ...
