What does the REM measure?

The amount of radiation exposure
The biological damage or risk from radiation energy
The speed of ionization
The duration of radiation the body is exposed to

The correct answer is: The biological damage or risk from radiation energy

The REM, or roentgen equivalent man, is a unit that quantifies the biological effect of ionizing radiation. It specifically measures the biological damage that radiation can cause to human tissue, taking into account the type of radiation and its impact on health. This is crucial for assessing the risk associated with radiation exposure, as different types of radiation (like alpha, beta, or gamma radiation) can have varying effects on biological systems. Understanding the REM is important for radiation safety because it helps professionals determine safe exposure limits and implement protective measures. The emphasis is on the potential harm to living tissue rather than just the amount of radiation exposure or the speed of ionization. Thus, the REM incorporates biological factors and risk into its measurement, making it essential for evaluating radiation safety standards and protecting public health.
