For a real time imaging technique using a fast neutron radiography (FN
R), a fast neutron television system (FNR-TV) was studied using the fa
st neutron source reactor YAYOI at the University of Tokyo. In order t
o obtain a good quality image with the FNR-TV, it is essential to deve
lop a high sensitive converter to detect fast neutrons. A sensitive pr
ototype 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 e
xperimental results. The analytical results agree well with the experi
mental results.
