health physics
Quick Summary
Health physics is a field dedicated to understanding and mitigating the medical and hygienic risks associated with exposure to radioactive radiation. This discipline is crucial because ionizing radiation, which can displace electrons from atoms and molecules, has been extensively studied for its biomedical effects.123
Applications of radiation in medicine are widespread, encompassing both diagnosis and treatment. Diagnostic procedures utilize radionuclides to visualize organ structures or study organ metabolism. Imaging techniques, such as X-rays and magnetic resonance imaging (MRI), create detailed internal views of the body. Radiation therapy, a primary treatment for cancer, uses high-energy radiation to destroy cancerous cells.452
Despite its benefits, radiation exposure carries risks, including potential mutagenic or carcinogenic activity. Therefore, health physics emphasizes minimizing unnecessary exposure through established limits on radioactivity and radiation doses for both workers and the public. Every medical use of radiation is carefully evaluated to ensure its benefits outweigh the calculated risks.6
