WebWe can use the half life of the substance to do this. The half life of Bismuth-210 is 5 days. This says that after t = 5, the original population of 800 mg has decay to half of its original amount, or (800) 400 2 1 = mg. Mathematically, since P(t) represents that amount of population of the substance left after time t, this says that P(5) =400 ...
