Abstract:

The calibration of beta counting systems used for the quantitative determination of radionuclides in air filter collections is described. Solid calibration standards are prepared from a variety of standardized sources of radioisotopes of different beta energies by mounting in a reproducible geometry 50.0- and 25.0-mg quantities of carrier material containing known amounts of radioactivity. A calibration curve of counting efficiency vs. beta-max energy is constructed for each counting system, from which the counting efficiency of a wide variety of radionuclides having nonforbidden spectra can be derived.
