Half-life of 241 Am is given. The number of alpha particles emitted each second by a 5 .00 g sample of 241 Am is to be calculated. Concept introduction: Americium- 241 is used in smoke detectors. It decays by emitting α particles. The radiation emitted by this element ionizes particles that are then detected by a charged particle collector. Decay constant is the quantity that expresses the rate of decrease of number of atoms of a radioactive element per second. Half-life of radioactive sample is defined as the time required for the number of nuclides to reach half of the original value.
