Neutron radiography with fast neutron beams (FNR) has been studied at the f
ast neutron source reactor "YAYOI" of the University of Tokyo since 1986. I
maging techniques for FNR have been developed for CR-39 track-etch detector
, electronic imaging system (television method), direct film method, imagin
g plate and also fast and thermal neutron concurrent imaging method. The re
view of FNR imaging techniques and some applications are reported in this p
