指样品在一年时间长度所受的α,β和γ以及宇宙线的剂量。
ResultsDuring 2002 to 2008,2 799 person/times were surveyed,the average annual dose equivalent was 1.37±2.14. From 2002 to 2008,it was 1.71±1.40,1.36±1.62,1.59±3.47,1.28±2.22,1.35±1.90,1.20±2.15 and 1.22±1.63 mSv respectively,which decreased year by year(P<0.05).
结果2002~2008年累计监测2799人次,人均年剂量当量为1.37±2.14mSv,各年分别为1.71±1.40、1.36±1.62、1.59±3.47、1.28±2.22、1.35±1.90、1.20±2.15、1.22±1.63mSv,人均受到职业照射的年剂量当量呈逐年下降趋势(P<0.05)。

结果通过估算和实测,各个关心点的年剂量当量均小于剂量约束目标值。
Results By estimation and measurement, annual dose of each concerned point is proved to be smaller than the defined dose.
而这个“最大剂量”,只是提升致癌风险年辐射最低剂量的一半。再看这个“提升致癌风险年剂量最低值”,只是致命辐射量数值的80分之一。
This, in turn, is half of the lowest one-year dose clearly linked to an increased cancer risk, which, in its turn, is one 80th of an invariably fatal exposure.
在处理此次事故中的工作人员,由于没有保护手段,数小时内接受的辐射量相当于人一年内接受的辐射最大剂量。
At one stage an unprotected person at the main gate would have received the maximum allowable yearly dose for a nuclear-industry worker in a matter of hours.
