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.
