Survey instruments must be calibrated at least once each year and after every service.

The RSO provides calibrations free of charge upon request for survey meters that were approved by the RSO in advance of procurement. In such cases, the authorized user must furnish the RSO with a copy of the instruction manual.

An authorized user may elect to utilize the calibration services of another qualified provider. The authorized user must submit a copy of the calibration certification to the RSO immediately after calibration for record retention purposes. The annual calibration frequency must still be maintained.

If work with radioactive materials is to continue while an instrument is being calibrated or repaired, the authorized user may obtain a temporary loaner instrument from the RSO.

The RSO is required to track all swipe sample counting equipment that is used for compliance-required surveys and to assure that "technical standards" are being maintained on this equipment. There are 18 LSCs on the Pullman campus that now meet the "technical standard" required by the State for swipe sample counting for compliance-required facility contamination surveys. A list of these machines is available via this link. Equipment approved for use in compliance-required surveys. This list will be updated on a regular basis.
