Correction for the Gamma-Ray Sensitivity of the Beta-Counter in the Standardization of Cobalt-60 by the Beta–Gamma Coincidence Method
The standardization of radioisotopes by the BETA - gamma coincidence method involves correcting the observations to obtain the true disintegration rate, which is usually done for the gamma radiation by screening the counter from the source by placing between counter and source an absorber of such a thickness that it absorbs all the BETA radiation. Such a method usually alters the sensitivity of the BETA counter. In an attempt to solve this problem for Co/sup 60/ a pulse-amplitude analyzer was incorporated following the BETA -ray detector of the BETA -- gamma coincidence counting equipment. The efficiency of such a system is analyzed, and methods of varying the efficiency for each type of radiation from Co/sup 60/ is discussed. (J.S.R.)
