THE EXPERIMENTAL DETERMINATION OF THE CORRECTION FACTORS k(t) FOR THE FAST FISSION FACTORS MEASUREMENTS

Ender Erdık

Abstract

The determination of conversion factors k(t), as functions of the time after end of exposure, to convert a measured ratio of U/sup 238//U/sup 235/ fission-product BETA activities to a true fission rate ratio is carried out by the double-fission-chamber method. The ratio of U/sup 238//U/sup 235/ fission- product BETA activities can be taken in place of the fission rate ratio using on the average a 60-min waiting time after the end of the exposure and a 10-min counting time. Under these circumstances, the average value of the conversion factor k(t) is found to be equal to unity. (auth)
