Description

technical field [0001] The invention relates to the technical field of radiation shielding plates, in particular to a high-performance composite particle material and a radiation plate for shielding neutron gamma radiation. Background technique [0002] With the rapid development of modern science and technology, the dependence on energy is becoming more and more intense. An invisible and intangible pollution source has attracted more and more 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 been widely valued. Neutrons are the only ionizing radiation that can make other substances radioactive. When neutron flow interacts with substances, it mainly interacts with substances. Nuclei interact with each other, thereby easily generating nuclear fragments, which in turn cause secondary radi...
