NBS (National Bureau of Standards) measurement services: radioactivity calibrations with the 4 pi gamma ionization chamber and other radioactivity calibration capabilities. Special pub. (Final)
Technical Report
·
OSTI ID:5656787
The paper describes the use of the NBS 4 pi' gamma ionization chamber - an instrument which provides an indirect method of comparing the activity (decays per second) of gamma-ray-emitting radionuclides with national standards for a routine calibration service by the National Bureau of Standards Radioactivity Group. A description of the chamber's construction and characteristics, the operational procedure, and the associated equipment is included. A description of NBS capabilities for direct radioactivity calibrations is also presented. Many of these capabilities are used to establish calibration factors for the 4 pc gamma ionization chamber.
