Under regulations, if there is over-exposure of a film badge, to whom should the findings be reported and within what timeframe?

• A. Phone the RHB immediately
• B. Phone the RHB within 24 hours
• C. Report the findings to the RHB within 30 days
• D. Take no action personally, this is a CDPH matter

Answer: (C)

When a film badge shows over-exposure, a formal regulatory report is required to document what happened and support corrective actions. The findings must be submitted to the Radiation Health Branch within 30 days. This timeframe allows a thorough written report that includes the exposure details, personnel involved, equipment and procedures, investigation results, and planned corrective measures. The Radiation Health Branch is the appropriate regulatory body to receive this information (CDPH is the department that houses that branch, but the reporting goes to the RHB). Immediate phone notification isn’t the standard requirement; the 30‑day written report ensures proper regulatory review and record-keeping.
