An update on “dose calibrator” settings for nuclides used in nuclear medicine

Abstract

Most clinical measurements of radioactivity, whether for therapeutic or imaging nuclides, rely on commercial reentrant ionization chambers (“dose calibrators”). The National Institute of Standards and Technology (NIST) maintains a battery of representative calibrators and works to link calibration settings (“dial settings”) to primary radioactivity standards. Here, we provide a summary of NIST-determined dial settings for 22 radionuclides, including several previously unreported settings. In general, current manufacturer-provided calibration settings give activities that agree with NIST standards to within a few percent.
