The term "radiation risk" refers to the potential harm that may result from exposure to ionizing radiation. This type of radiation, which includes X-rays and gamma rays, has enough energy to remove tightly bound electrons from atoms or molecules, causing damage to living tissue. The severity of this damage depends on several factors including the dose, duration, and type of exposure. Radiation risk is generally higher for higher doses and longer durations of exposure, but even low levels of radiation can pose a threat over time, particularly in sensitive tissues such as bone marrow or reproductive organs. The concept of "radiation risk" is often used to inform decisions about the use of medical imaging procedures that involve ionizing radiation and to establish safety guidelines for workers who may be exposed to higher levels of radiation in their jobs, such as nuclear power plant employees.
