Health Physics meaning

Health physics is the professional discipline of radiation protection: applying radiation physics and radiation biology to enable the safe, lawful use of ionising radiation and radionuclides in settings such as nuclear installations, hospitals, laboratories and industrial radiography. In legal practice it is a descriptive term (not generally defined in statute), but health physics activities underpin compliance across the UK and Ireland with the Ionising Radiations Regulations 2017 (GB), Ionising Radiations Regulations (Northern Ireland) 2017, the Radiation (Emergency Preparedness and Public Information) Regulations 2019, environmental permitting regimes, and Irish ionising radiation and medical exposure regulations. Health physicists advise on dose limits and constraints, the ALARP principle, classification of workers, designation of controlled and supervised areas, local rules, dosimetry, monitoring and record-keeping, shielding design, contamination control, radioactive waste and discharges, transport of radioactive material, emergency planning, and training. They may act as or support the appointed Radiation Protection Adviser (RPA) or Radiation Protection Supervisor (RPS) in Great Britain, and equivalent advisory roles in Northern Ireland and Ireland, and liaise with regulators (HSE, ONR, EA/SEPA/NRW; HSENI; EPA Ireland). Their work is central to licensing, permits, audits, due diligence, incident response and litigation concerning occupational and public exposure. Usage and regulatory expectations are broadly consistent across...
