Immediate notification is required for an eye dose equivalent of how many rems?

• A. 5 rems
• B. 25 rems
• C. 50 rems
• D. 75 rems

Answer: (D)

The lens of the eye is highly sensitive to radiation, so safety programs include action levels for eye dose that trigger escalation. Immediate notification is required when the eye dose equivalent from a single exposure reaches a very high level, to prompt swift review and corrective action by the Radiation Safety Officer. The threshold set for this urgent alert is 75 rem. At or above this amount, it signals a significant overexposure event that needs prompt investigation, shielding assessment, and changes to reduce future risk. Lower values still require monitoring and follow-up, but do not demand immediate notification.
