Abstract The types and hazards of nuclear radiation are introduced in this paper. It is proposed that the main task
for the nuclear shielding design is shielding neutron and γ-ray. Meanwhile, the research status of nuclear radiation
shielding materials at home and abroad are summarized in detail. The principal problems for the current compre‐
hensive neutron and γ-ray shielding materials are discussed. The conflict between shielding effectiveness and other
performances needs to be settled. The research on radiation shielding materials is prospected. It is pointed out that
the development of structure（mechanical performance, heat resistant stability and etc）-function（neutron and γ-ray
shielding properties）integration radiation shielding materials is the future developing trend.
