摘要: 针对高活度废放射源整备建立了可移动废放射源整备屏蔽实验装置,利用该装置,从工程运用角度开展了忻州沙的粒径、密度测量和屏蔽实验,筛选出了适合废放射源整备使用的特定类型沙子。研究结果显示:采用厚度150 cm饱和含水忻州建筑沙作为屏蔽材料,可确保1 000 Ci 60Co废放射源整备时在屏蔽装置外产生的剂量率小于0.03 mSv/h。

Abstract: Shielding experiment devices were established for high activity disused radioactive sources conditioning study. The shielding performance of different types of Xinzhou sands with different particle size and different density as well as different water contents were studied for engineering application. The suitable sands were chosen for high activity disused radiation sources conditioning. Results show that the dose rate will be controlled below 0.03 mSv/h by using 150 cm Xinzhou water saturated sands for construction as shielding material while conditioning 1 000 Ci 60Co radioactive source.

Key words: high activity, spent radioactive source, conditioning, shielding, sands, density
