Design of a new temporary shielding device which can be installed remotely

In order to effectively reduce the installation dose, a new temporary shielding device that can be installed at a long distance has been developed. The shielding device uses flow-type granular tungsten particles or lead particles as the main shielding material, air as the transport medium, and the high-pressure airborne device as the main power system to realize the long-distance transport and filling of the shielding material particles. The shielding device can provide a reference for improving the level of radiation protection in the field. (authors)
