Radiation biology refers to the study of the effects of ionizing radiation on living organisms. It plays a crucial role in understanding the impacts of radiation exposure and implementing safety measures. There are different terms used as synonyms for radiation biology, such as radiobiology, radiation toxicology, radiation health physics, and medical radiation sciences. Radiobiology is more focused on the biological effects of radiation while radiation toxicology studies the toxic effects of radiation on living organisms. Radiation health physics deals with radiation detection and protection, and medical radiation sciences emphasize the use of radiation for medical purposes. These fields are interconnected and often collaborate to achieve a better understanding of radiation effects.
