Radioactive Decay - Jim Hartnett. 2. Radioactive Decay. A nucleus may be bound in a relatively high energy state, and if it can attain a lower energy, it will eventually do so. Nuclear Stability . Nuclear stability . means that nucleus is stable meaning . that it . does not spontaneously emit any kind of radioactivity (radiation). . On the other hand, . if the . nucleus is unstable (not stable), it has the tendency of emitting some kind of . low-temperature microcalorimeters. Some preliminary ideas and results. Michael W. Rabin.

When the nucleus of an atom possesses either too many or too few neutrons compared to the number of protons it becomes unstable. These are called radioactive isotopes. Unstable nuclei split up in a process called radioactive decay and emit radioactive radiation..
