Under the conditions of, its physical and mechanical properties quite stable, the 10BN and 6LiF of addition neutron absorption cross-section are big, ensure that neutron shield
Effect, polyether-ether-ketone resin are heat-resistant polymer, and due to its outstanding durability high flexibility of adhesion with fibrous material
Remarkably so that be suitable as shielding material, also, because hydrogen density is high, fast neutron efficiently reduced, during it can not only be shielded
Son, it is also prevented from the radiation of alpha ray, β rays, proton, gamma-rays, X ray etc. so that composite absorption layer i.e. can be more abundant
Absorption radiation, so as to reduce the amount of radiation for penetrating sheet material；
(6) first lead layers and the second lead layer can largely stop that neutron gamma radiates, and composite absorption layer is used to absorb spoke
Penetrate, i.e. radiation sequentially passes through the first lead layer, composite absorption layer, the second lead layer, shields a part, its remaining part by the first lead layer first
Divide through composite absorption layer, absorbed a part, remainder is largely shielded by the second lead layer, and composite absorption layer is set
Into wavy, the entire area of composite absorption layer can be increased, so as to increase the degree of absorption to radiation, that is, reduce radiation through
The amount of sheet material, and screen layer is filled with the gap formed between composite absorption layer and the first lead layer and the second lead layer, can be with
Further improve the radiation-screening effect of sheet material.
