为了解在普通实验室里使用开放性放射性制剂对环境所致污染状况，对六个使用放射性免疫药盒和少量标志化合物的普通实验室进行现场测量。结果表明各种有关表面的放射性活度在０～４．５Ｂｑ·ｃｍ－２之间，各实验室的γ辐射水平也近乎本底。
To understand the environmental pollution caused by the use of open-label radiopharmaceuticals in general laboratories, on-site measurements were performed on six general laboratories using radioimmunoassay kits and a small number of marker compounds. The results showed that the radioactivity of various related surfaces was between 0 and 4.5 Bq · cm-2, and the γ radiation levels of all laboratories were near the background.
