Health physics is the study of the risks of ionizing radiation to people and the environment. Neutron radiation, which can cause ionizing radiation although not often ionizing radiation itself, and which poses similar hazards, is also considered. Health physics encompasses many disciplines, including physics, biology, chemistry, and ecology.

Compare to Industrial hygiene, the study and practice of protecting against the chemical toxicity of both radioactive and nonradioactive substances. The schism between the two disciplines has occasionally caused problems.
