近年来,随着电子束热源被广泛地应用于钻孔、焊接、烧结、熔融、提纯、镀膜、单晶制备以及合金熔炼等领域;伴随而生的X射线对于操作者的危害日益引起人们的注意。尤其高能电子束设备更是如此。本文仅就电子轰击炉强流电子枪所产生的X射线的形成、危害、计算与防护等进行定性描 In recent years, with the electron beam heat source widely used in drilling, welding, sintering, melting, purification, coating, single crystal preparation and alloy smelting and other fields; X-ray generated by the hazards to the operator is increasingly causing people note. In particular, high-energy electron beam equipment is even more so. This article only on the electronic bombardment of strong current electron gun generated X-ray formation, damage, calculation and protection of qualitative description
