For how long should survey records and calibrations be retained for compliance?

The appropriate duration for retaining survey records and calibrations for compliance is three years. This timeframe is important because it aligns with the regulations and standards set by governing bodies overseeing radiation safety practices, which can include state regulations and the recommendations of organizations like the National Council on Radiation Protection and Measurements (NCRP) and the American National Standards Institute (ANSI).

Retaining records for this period ensures that an adequate history of the facility's radiation protection practices is available for audit and review. It demonstrates ongoing compliance with safety protocols and regulatory frameworks, allows for trend analysis in radiation safety practices, and provides a record should any discrepancies or concerns arise in the future.

While it might seem prudent to keep records for longer periods, the established three-year retention requirement typically balances the need for oversight with practical considerations regarding record management and resource allocation.
