Quality assurance of reference calibration field. Proposal of reference dose value intercomparison using RPL glass dosemeter

The method for a reference dose value intercomparison of calibration field using radiophotoluminescence (RPL) glass dosemeters was provided. This method was applied to the intercomparison of the reference exposure value of gamma irradiation fields among the 5 calibration facilities of Power Reactor and Nuclear Fuel Development Corporation (PNC). The results showed a good agreement by as much as 4% of deviation. These prove that reference exposure values of each calibration facility have been maintained in a good accuracy. It was shown also that the RPL glass dosemeters could be applied to a check of exposure value of a calibration field. This method will be available for the intercomparison programme among the Regional Cooperative Agreement (RCA) member states. (author)
