If an employee is likely to receive more than 10% of their annual occupational dose limit, what is required?

• A. Personnel monitoring devices
• B. Weekly safety training
• C. A change of job duties
• D. No action required

Answer: (A)

The key idea is protecting workers by tracking their personal radiation exposure when there’s a real chance it will approach the yearly limit. If an employee is likely to receive more than about one-tenth of that limit, a personnel monitoring device (a dosimeter) must be provided and worn. This device records the actual dose the worker accumulates, giving a precise measure of exposure, supporting ALARA, and helping ensure regulatory compliance. It also helps trigger any needed changes to procedures or protective measures if readings rise.

Weekly safety training, while important, isn’t dictated by this threshold. A change of job duties isn’t automatically required by this rule, and taking no action would fail to protect the worker or demonstrate compliance.
