What does REM measure in the context of radiation?

REM, which stands for roentgen equivalent man, is a unit of measurement that quantifies the biological effect of radiation exposure on human tissue. It takes into account not only the amount of radiation energy absorbed but also the potential biological damage that can result from that exposure. This is crucial in radiation safety as it helps to evaluate the risk associated with different types of radiation, considering factors such as the type of radiation and the sensitivity of the different tissues and organs in the body.

The context of this measurement is important in various fields, including radiation therapy, occupational safety, and health physics, where assessing risk to human health is vital. By using REM, professionals can create guidelines and regulations that protect individuals from the harmful effects of radiation, making it a fundamental part of radiation safety protocols.
