When is an employee dose monitoring plan required?

• A. Only when there is confirmed exposure above limits.
• B. When there is potential for exposure above regulatory thresholds; typically required for radiology facilities and other operations.
• C. For all facilities regardless of exposure potential.
• D. When employees request monitoring.

Answer: (B)

A dose monitoring plan is required whenever there is a real potential for occupational exposure to ionizing radiation to approach or exceed the regulatory limits. The idea is proactive safety: if workers could potentially receive doses above allowed thresholds, a formal monitoring program is put in place to track their exposure, use dosimeters properly, and take timely actions to keep doses as low as reasonably achievable. This is common in settings like radiology departments and other operations where radiation exposure is possible, because the risk exists even before any actual overexposure occurs.

It's not about waiting for a confirmed overexposure, and it's not needed in every facility if there is no meaningful potential for exceeding limits; and it isn't something that should depend on an employee asking for monitoring. The plan is a regulatory safeguard based on exposure potential, ensuring workers are observed and protected whenever the chance of higher doses exists.
