为了解铁选矿生产中应用的含密封源核仪表的放射防护状况,选择某铁矿选厂266台含密封源核仪表为调查对象,进行放射防护检测。结果显示,使用的密度计的数量及辐射剂量均大于其他核仪表。在正常生产状态下,铁选矿生产中使用的含密封源核仪表辐射剂量率水平符合放射卫生标准要求。
In order to understand the radiation protection status of sealed source nuclear instruments used in iron ore dressing production, 266 iron-bearing dressing plants with sealed source nuclear instruments were selected as the object of investigation and radioprotection testing was conducted. The results showed that the number of densitometers used and the radiation dose were greater than those of other nuclear instruments. Under normal production conditions, the radiation dose rate of sealed source nuclear instruments used in the iron ore dressing production meets the requirements of radiation health standards.
