Gd-148 is a radioactive isotope that decays by alpha emission. Each alpha particle emitted carries 5.10E-13 J of kinetic energy. A 80.0 kg worker is accidentally exposed to a sample of Gd-148 having an activity of 0.0500 curies for a total of 5.00 minutes. During that time the workers body absorbs 5.00 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
