Americium-241 is widely used in smoke detectors. The radiation released by this element ionizes particles that are then detected by a charged-particle collector. The half-life of 241Am is 432.2 years, and it decays by emitting alpha particles. How many alpha particles are emitted each second by a 2.20 g sample of 241Am?
