For a real time imaging technique using a fast neutron radiography (FNR), a fast neutron television system (FNR-TV) was studied using the fast neutron source reactor YAYOI at the University of Tokyo. In order to obtain a good quality image with the FNR-TV, it is essential to develop a high sensitive converter to detect fast neutrons. A sensitive prototype converter made of polypropylene (PP) resin and ZnS(Ag) mixture was recently developed. It was called a PP converter. In this paper, the mechanism models of luminescence for fast neutrons and gamma-rays in the PP converter are presented as well as the comparison with the experimental results. The analytical results agree well with the experimental results.
