Health Physics
Health physics, also known as the science of radiation protection, is the profession devoted to protecting people and their environment from potential radiation hazards, while making it possible to enjoy the benefits of the peaceful use of ionizing radiation.
Pronunciation
Health Physics: /ˈhɛlθ ˈfɪzɪks/
Etymology
The term "health physics" is derived from the goal of this field, which is to ensure the safe use of ionizing radiation for health-related purposes. The term "physics" refers to the application of physical principles in this endeavor.
Related Terms
- Ionizing radiation: Ionizing radiation is radiation with enough energy so that during an interaction with an atom, it can remove tightly bound electrons from the orbit of an atom, causing the atom to become charged or ionized.
- Radiation protection: Radiation protection, also known as radiological protection, is defined by the International Atomic Energy Agency (IAEA) as "The protection of people from harmful effects of exposure to ionizing radiation, and the means for achieving this".
- Radiation hazard: A radiation hazard is a dangerous condition that can cause death or injury through exposure to radiation.
- Radiation safety: Radiation safety involves the measures used in blocking or reducing radiation exposure by shielding, distance, or time.
- Radiation dose: A radiation dose is the amount of radiation energy absorbed by the body.
- Radiation biology: Radiation biology is the study of the action of ionizing radiation on living things, including the health effects of radiation.
- Radiation therapy: Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is therapy using ionizing radiation, generally as part of cancer treatment to control or kill malignant cells.
- Radiation monitoring: Radiation monitoring involves the measurement of radiation dose or radionuclide contamination for reasons related to the assessment or control of exposure to radiation or radioactive substances, and the interpretation of the results.
