For large systems consisting of billions of billions of radioactive atoms (instead of just 50 dice) in which many atoms decay in each fraction of a second, it becomes The smaller the chance of decay, the longer the half-life (time for half of the sample to decay) of the particular radioactive isotope. Ronaldo Degazon Wednesday 6/02/13 Physics Lab #20 – Radioactivity 1 Discussion: Radioactive decay is the process by which by which an atomic nucleus of an unstable atom loses energy by emitting ionizing particles. The radiation produced during radioactive decay is such that the daughter and to view an interesting Cloud Chamber Demonstration from the Jefferson Lab. Occasionally an alpha particle (4He nucleus) pops off. I usually perform it after I have introduced radioactive decay and talked about how it works.
