本文对广西29家糖厂使用的核子称的放射源进行了调查。结果表明 :在放射源工作状态下 ,在距铅室表面5cm、100cm及200cm的前、后、左、右、上及下方位的各监测点所监测到的γ辐射剂量当量率 ,除了前方(主射线束)外 ,其余各方位均符合国家标准限值要求。主射线束在铅室表面200cm处也达到了标准限值以下。辐射剂量估计的结果完全达到国家标准要求。核子称具有计量准确、操作简便、使用安全可靠等优点 ,值得推广使用。
This article investigated 29 nuclear sources used by Guangxi’s sugar mills. The results show that when the radioactive sources are in working condition, the equivalent dose rate of γ radiation monitored at each monitoring point of 5 cm, 100 cm and 200 cm from the front of the lead chamber at the front, rear, left, right, up and down, Main beam), the rest of the azimuth are in line with national standards limit requirements. The main beam has also reached below the standard limit of 200 cm at the lead chamber surface. The result of radiation dose estimation fully meets the requirements of national standards. Nuclear said with a measurement accuracy, easy to operate, the use of safe and reliable, it is worth promoting the use of.
