radiation dose

Radiation dose refers to the amount of energy from radiation absorbed by a person or an object. It is measured to understand potential health effects, as different types and amounts of radiation can cause varying levels of biological impact. The dose is typically expressed in units like grays (Gy) or sieverts (Sv), which account for the radiation type and its potential to cause damage. In everyday life, we are exposed to natural background radiation, but higher doses, such as those from medical imaging or radiation therapy, are closely monitored to ensure safety and minimize risks.
