Abstract

The application provides a preparation method of X-ray and gamma-ray protective powder. Sheet structure of bismuth tungstate and graphene oxide in the X-ray and gamma-ray protective powder prepared according to the preparation method provide effective scattering for X-ray and gamma-ray; a multi-bandgap system formed of nano rare-earth oxide can provide multistage absorption for X-ray and gamma-ray; metallic elements can shield X-ray and gamma-ray; the synergy of the multiple effects provide great protection for X-ray and gamma-ray of different energy levels; in addition, the prepared X-ray andgamma-ray protective powder has zero lead and light weight and has a promising application prospect in X-ray and gamma-ray radiation protection.

Description

technical field [0001] The present application relates to the field of radiation protection, in particular to a preparation method of X and gamma ray protective functional powders. Background technique [0002] In recent years, with the rapid development of national defense scientific research, radiation medicine and atomic energy industry, the use of various rays has become increasingly widespread. X and gamma rays are important ones. Long-term exposure to X and gamma rays can cause damage to gonads, mammary glands, hematopoietic bone marrow, etc. Excessive doses can even cause cancer, posing a serious threat to the human body. Therefore, according to the properties of X and γ-rays and their mechanism of action with substances, corresponding materials should be selected and prepared for protection. [0003] Metal materials such as lead plates and iron plates were first used for X and gamma ray shielding. Later, leaded glass, plexiglass and rubber products were developed a...
