STANDARDIZATION OF BETA COUNTING PROCEDURES USED AT NRL IN THE RADIOCHEMICAL ANALYSIS OF AIR FILTER SAMPLES.
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.
