RADIATION HAZARD AND PROTECTION OF LOW ENERGY ACCELERATORS

RADIATION HAZARD AND PROTECTION OF LOW ENERGY ACCELERATORS 1 first-author Institute of Nuclear Science and Technology, Sichuan University, Chengdu 610064, China Institute of Nuclear Science and Technology, Sichuan University, Chengdu 610064, China In this paper, the origin and type of radiation hazards as well as the main aspects of radiation protection for low-energy accelerators are discussed in general, and the problems of radiation protection and the experimental results of the operational monitoring of the five accelerators in the Institute of Nuclear Science and Technology, Sichuan University, namely, one 1.2 M cyclofron, two ·Cockroft-waltons and two Van de Graafts, as well as a powerful electron accelerator for industrial irradiation are described. The discussion and evaluation are made according to the requirments of the National standards GB 5172-85.
