A set of apparatus for the measurement of 4πγ radiation activity have been developed in order to measur the activity of sealed γ source of 5×103~1×1011 Bq. The paper describes the working principle and structure of the apparatus. The specifications and performances of the system have been tested and examined. The conventional true values of activity of γ source have been measured and its uncertainty has been assessed.
