摘要
本文介绍一种组合式方形铅屏蔽室的新设计,用作同轴型高纯锗探测器的屏蔽室。选用五十年代电解铅作主屏蔽材料。在0—2.7MeV能区,本底降低到原来的0.5％,本底计数为72个/min。
A new square lead shield room has been introduced in this article. It is used as the shield room of coaxial high-purity germanium detector. The old lead as the material of shielding has been choised. After using this equipment,the background is 0.5% as it was.The counts of the background between the energy of 0-2.7 MeV is 72 cpm.
