Description

This paper puts forward a new method measuring the activity of neutron-activation-foil using 4πβ-γ coincidence equipment without making thin film source. By changing the voltage of photomultiplier tube, keeping the same efficiency of the γ detector in detection of γ photon and X ray of K shell, we can obtain the activity of neutron-activation-foil, without using efficiency extrapolation method. Theory analysis indicates that the method is feasible. (authors)
