We show that it is reasonable to develop one of the types of new high-performance radiation-protective materials, namely, 'light metal + heavy metal' multilayer composites. The characteristics of the internal architecture of Al-Pb composites prepared by the successive application of vacuum and normal atmospheric rolling are presented. The difference between the radioisotropic and accelerated methods of experimental testing of the radiation-protective properties of materials are described. We analyze the results of testing of the composites and the influence of their structure on the radiation-protective characteristics of the investigated materials. It is shown that the radiation-protective efficiency of the composites of certain structure is higher than for aluminum by 30-40%. This enables us to reduce the weight of radiation-protective structures with preservation of the efficiency of protection on the level of aluminum or increase the efficiency of protection for a constant weight of the structure.
