The wide range of calibrator-type instruments currently being used primarily for radionuclide assay in nuclear medicine indicates the need for a standard for uniformity in measurement and test techniques. Such devices are composite systems consisting of an ionization chamber integrally coupled to appropriate electronic circuitry that converts the ionization current to a readout in units of activity. The principles of operation of the ionization chamber are well summarized in the NCRP Report No 58 [1] 1 and will not be repeated here. Wide activity range and stability are useful characteristics of ionization chambers in this application. The advantages of this type of system for radionuclide assay include ease of use and interpretation.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
