Abstract
A comparison is made between the Variable Dead Time Counter (V.D.C.) and Shift Register neutron coincidence systems for the assay of ru. With both systems the total neutron emission of the source is detected by BF, proportional counters embedded in a moderator assembly and the fraction arising from spontaneous fissions, which 240 is proportional to the amount of Pu present, is estimated.
