一些小水泥厂为减轻劳动强度,减少粉尘危害,开始应用科技大学新研制的γ射线双点料位计自动化装置,工人只在室内看仪表操作。此是以两个22.5毫居里点状~(80)钴作放射源,源外用一定厚度铅罐密封防护,安装在机窑离地面1～2m处。为进行辐射安全评价,1985年4月对刚使用此装置的贵池县殷汇镇、东至县张溪镇两座小水泥厂进行了γ外照射量
Some small cement factories in order to reduce labor intensity and reduce dust hazards, began to use the new technology developed by the University of gamma-ray two-point level gauge automation devices, workers only indoors to watch the instrument operation. This is based on two 22.5 millicuries of Curium ~ (80) cobalt as a radiation source, the source of a certain thickness of the lead seal protection, installed in the kiln from the ground 1 ~ 2m Department. In order to carry out the radiation safety assessment, in April 1985, the two small cement plants in Yinhui Town and Zhangxi Town, Dongzhi County, just using this device, were subjected to γ external irradiation
