What term refers to the total harm to health experienced by a population exposed to a radiation source?

• A. Detriment
• B. Risk
• C. Hazard
• D. Burden

Answer: (A)

Detriment refers to the total health impact on a population exposed to a radiation source. It combines both how likely radiation-induced health effects are and how severe those effects can be, across everyone in the group. This population-wide measure, often called collective detriment, uses the collective dose and risk coefficients to estimate the overall health burden from the exposure. In contrast, risk focuses on the chance of a given adverse effect for an individual, hazard is the potential to cause harm, and burden is a broader public-health term not specific to radiation effects. So the best term for total health harm in a population exposed to radiation is detriment.
