FW: [ RadSafe ] Question about calculating activity

[Marcel Schouwenburg]

Given the molecular weight and the mass of your compounds you can
determine the number of moles, e.g. the number of  atoms of each kind -
provided you know or can reasonably assume the isotopic composition in
your compounds. Given the number of radioactive atoms and their
half-life, the activity results.
