Movable box type combined shielding system

Abstract

The invention discloses a movable box type combined shielding system which comprises a container, an in-box radiation shield, an out-box radiation shield and a photon shielding plate. A radioactive source generating device is arranged in the container; the space between the radioactive source generating device and the inner wall of the container is fixedly filled with the in-box radiation shield; the outer wall of the container is detachably covered with the out-box radiation shield; the photon shielding plate is arranged on the outer wall of the container in a sliding mode and used for sliding to an active area when the out-box radiation shielding body is detached to shield active area rays. According to the movable box type combined shielding system, the radioactive source generating device can run and be transported in the container; when the radioactive source generating device runs, the in-box radiation shield and the out-box radiation shield can be combined to shield high-dose radiation generated when the radioactive source generating device runs; when a container body is transported, the in-box radiation shield and the container body are detached, and the photon shielding plate moves to the active area to shield rays generated by neutron activation of a container active area structure material.

Description

technical field [0001] The invention relates to the field of nuclear radiation shielding, in particular to a movable box-type combined shielding system. Background technique [0002] In order to shield various rays generated during the operation of the radioactive source generating device, the radioactive source generating device is generally located in a shielded factory building surrounded by thick radiation shielding walls. Radiation shielding walls are generally made of materials such as steel plates, lead plates, and special cement, relying on the stacking of a large number of shielding materials to ensure radiation safety, resulting in a heavy overall shielding system that takes up a large space and cannot be moved. [0003] For transportable mobile radioactive source generating devices, such as mobile nuclear reactor generating devices, during the operation or transportation of the device, it is necessary to shield the high dose level of radiation generated by the rad...
