Abstract

The invention provides a shielding device for controlling an irradiation dose of an electron beam. The shielding device comprises a bottom plate, a support, a plurality of supporting columns, whereinthe supporting columns are fixed above the bottom plate, a liquid container arranged on the support and comprising a container main body and a container top plate, a fixing piece used for fixing the container top plate on the container main body in a height-adjustable manner, and optionally, a liquid level meter disposed on an outer side of the container main body, wherein a liquid is contained between the container main body and the container top plate. The invention also provides a shielding method for controlling the irradiation dose of the electron beam.

Description

technical field [0001] The invention belongs to the field of radiation processing, in particular to a shielding device and method for controlling the radiation dose of electron beams. Background technique [0002] Radiation processing is a processing process for processing substances or materials by irradiating substances with radiation to produce physical effects, chemical effects and biological effects. It is a new technology of safe, efficient, energy-saving and green processing. At present, radiation processing mainly uses radioactive isotopes such as 60 Co or 137 The γ-rays emitted by Cs and the high-energy electron beams or bremsstrahlung X-rays generated by the accelerator. [0003] When high-energy electron beams are used for irradiation processing, the object to be irradiated is generally placed in the tray of the under-beam device, and the under-beam device is operated to make the object to be irradiated sequentially pass under the beam extraction window of the a...
