The remote calibration of radioisotope calibrators

the new calibration technique ‘e-trace’ has been developed by AIST. Using e-trace, measurement equipment in remote place can be calibrated in short time and limited resources. We calibrated radioisotope calibrators of JRIA and NMCC remotely. It was confirmed that the results of remote calibration was consistent with those of former method within uncertainty. As a result, e-trace is approved as a regular calibration method at AIST. We plan to apply remote calibration to the calibration of the radioisotope calibrators in hospitals and isotope facilities.
