摘要
针对元件厂的实际情况,假定了两种放射性核素的摄入模式:一种是持续且以恒定的速率摄入;另一种是不同速率下的随机摄入,这种情况下所有的摄入均可以监测周期的中点单次摄入来代替。对应于连续摄入模式下的两种假定类型,建立了两种摄入量和剂量估算方法:"监测周期中点单次摄入法"和"均匀摄入法",并对估算结果进行了分析与修正。相对而言,"均匀摄入法"是比较细致的估算方法,尤其是对于一年的监测周期里生产过程中有停产的情况,应用该法估算剂量可能更可信。
According to the practice in the nuclear fuel plant,two modes of intake are assumed.The first mode is intake of radionuclides at a continuous and constant rate.The second is at a random and different rate,in which all intakes could be represented by an acute intake at the mid-point of the monitoring interval.Based on two assumptions,two different methods of dose assessment for occupational internal exposure are applied.Furthermore,the results of dose assessment are analyzed and revised.Relatively,the first mode is a more detailed method for dose assessment.Especially,in the circumstance of the production suspension in a 360-day monitoring interval,the dose results assessed using this mode is probably more credible.
