Personnel monitoring devices are required when an employee is likely to receive greater than what percentage of their annual occupational dose limit?

Explanation:
Monitoring devices are required when an employee is likely to receive more than 10 percent of their annual occupational dose limit. This threshold helps ensure that exposures are tracked for workers who could accumulate a meaningful dose in a year. For most adults, the annual occupational limit is 50 mSv (5 rem); 10 percent of that is 5 mSv (0.5 rem). If a worker’s anticipated dose approaches or exceeds that level, a dosimeter is used to measure actual exposure, support ALARA, and ensure compliance with regulations.
