Am-241 is a radioactive isotope that decays by alpha emission. Each alpha particle emitted carries 8.79E-13 J of kinetic energy. A 80.0 kg worker is accidentally exposed to a sample of Am-241 having an activity of 0.0250 curies for a total of 10.00 minutes. During that time the workers body absorbs 2.50 percent of the alpha particles emitted by the sample. How many alpha particles were emitted by the sample during the time of the workers exposure? Answer alpha particles...
