本文报道了在珠海白石集装箱查验场开展γ射线本底调查以及2年来对487批货物进行放射性监测的情况。根据测量得出该查验场γ射线平均剂量当量率为0.146+0.02μSv/h;通过对487批货物的放射性监测,发现石墨制品和火山灰的γ剂量当量率超过国家非放射性标准限值的1/3,其它货物的放射性值均接近本底值。 This article reports on the gamma ray background investigation conducted at the Baishi Container Inspection Site in Zhuhai and the radioactive monitoring of 487 shipments over the past two years. According to the measurement, the average γ-ray dose equivalent rate of the inspection field is 0.146 + 0.02μSv/h. Through radioactive monitoring of 487 batches of cargo, the gamma dose equivalent rate of graphite products and pozzolans exceeds the national non-radioactive standard limit of 1/1. 3, The radioactivity values ​​of other cargoes are all close to the background value.
