Abstract
In order to establish the radioactivity measurement standards a 4{pi}{beta}-{gamma} coincidence apparatus and a 4{pi}{gamma} ionization chamber have been installed in the laboratory. The 4{pi}{beta}-{gamma} coincidence apparatus is for absolute measurement, and its uncertainty is {+-}(0.3{approx}5)%. The 4{pi}{gamma} ionization chamber is for working standard, and its uncertainty is {+-}(1{approx}5)%. The combination of these devices can meet the quality requirements controlled by National Verification System in the transfer of radioactivity values.
