What is Nucleus?
The positively charged central core of an atom, containing protons and neutrons (except hydrogen-1, which has no neutrons). The nucleus has a diameter of about 10⁻¹⁵ m and accounts for nearly all the atomic mass. The strong nuclear force binds the nucleons together.

Nuclear reactions in atomic nuclei are exploited in nuclear power generation and nuclear medicine. Radioactive isotopes produced by nuclear reactions are used as tracers in medical imaging. Understanding nuclear structure guides the design of radiation therapy for cancer treatment.
Unstable nuclei emit ionising radiation that is hazardous to biological tissue. Nuclear material must be handled with strict safety protocols and appropriate shielding.
