Abstract

Neutron activation analysis using Au foil is a common and important method for measurement of thermal neutron fluence. To determine the activity of Au foil experimentally, Kawada et al. proposed 2πβ+2πβ-γ coincidence counting. This method is based on 4πβ-γ coincidence counting but a 4πβ detector is divided into two 2πβ detectors those are independently operated in the method. In this research the correction factors in 2πβ+2πβ-γ coincidence counting were obtained by measurement and simulation. The activities obtained by these correction factors were in good agreement.
