6.1 Requirements

Radiation monitoring instruments used for quantitative radiation measurements must be calibrated at intervals not to exceed 12 months as required by regulation.  This includes survey meters used in research labs and any other location where quantitative radiation determinations are needed.  Survey instruments that have never been calibrated or are out-of-calibration cannot be used.  Instruments found out-of-calibration by EHS will be tagged as “out-of-service."
