用坡莫合金作个人剂量仪的屏蔽材料

The Shielding Material of Personal Dosimeter with Permalloy

研究了用坡莫合金屏蔽层消除逆变电焊机等电器对核电站环境中使用的个人辐射剂量仪干扰的方法。提出了研究如电焊弧光之类干扰源的影响及防护的问题。对个人辐射剂量仪的抗干扰要求、相关标准的规定是否足够严密，提出了疑问。

The method for diminating the electromagnetic interference of electric devicessuch as inversion type welders with personal dosimeter in nuclear power stations by meansof permalloy shielding layer was studied.A new tapic was raised for research on effect ofinterference sources such as welding arc. It is doubt whether the existing standard forinterference-free requirements to personal dosimeter is rigorous enough or not.
