Description

Technical field [0001] The invention relates to the technical field of radiation shielding plates, in particular to a composite particle material and a radiation plate for high-intensity shielding of neutron gamma radiation. Background technique [0002] With the rapid development of modern science and technology, the dependence on energy has become more and more intense. An invisible and intangible source of pollution has received increasing attention from all walks of life. This is the radiation known as the "invisible killer". Therefore, how to reduce the radiation intensity , To effectively prevent radiation pollution, protect the environment, and protect human health, it has always been widely valued. Neutron is the only material that can make other materials radioactive ionizing radiation. When the neutron flow interacts with the material, it mainly interacts with the material. The nuclei of the nuclei interact, which easily generates nuclear fragments, which in turn trigge...
