It is also called anti radiation concrete, shielding concrete, atomic energy protection concrete, nuclear reactor concrete, heavy concrete, etc. It is an effective protection against harmful radiation to the human body, such as X-rays γ New type of concrete irradiated by X-ray and neutron ray. Generally, the method of increasing the density of concrete is used to improve the shielding ability of X-ray and y-ray, and the crystal water contained in cement stone or aggregate is used to slow down the high-speed neutron moderation.
