A nucleus may be bound in a relatively high energy state, and if it can attain a lower energy, it will eventually do so. Studying Effects of hazards. Risk Assessment & Risk Management.

Isotopes . 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..
