利用γ能谱分析方法,对宝钢等八个钢厂的钢样和铀同位素浓缩试验装置退役设各金属样品的放射性核素进行了分析,结果表明:八钢厂多数钢材中含铀量在6.5Bq/kg以下,个别钢样中含微量钍旷退役设备金属部件去污回炼后,锭中含铀量与市售钢材水平相当.铝质部件回炼后除个别样品的含铀量稍高外,多数样品含铀量为10—15Bq/kg.
The radionuclides of each metal sample were decomposed into steel samples and uranium isotope enrichment test devices of eight steel mills, including Baosteel, using gamma spectrometry. The results showed that the content of uranium in most steel products of the eight steel mills was between 6.5 Bq / kg or less, individual steel samples containing trace thorium mining equipment decontamination metal components decontamination, the amount of uranium in the ingot with the level of commercially available steel.Aluminum components in addition to a few samples after the high uranium content Most samples contain 10-15Bq / kg of uranium.
