本文报导了油田测井使用~(113m)I_n的现场防护监测,对井口周围的环境中的地表空气、水、植物等在使用同位素前后做了对比监测,结果经统计学处理,各类样品放射性水平无显著差异(P>0.05),操作人员体表性腺部位最大空气吸收剂量率69.84·10~(-6)Gy·h~(-1)。
This paper reports on-site monitoring using ~ (113m) I_n in oilfield logging. Before and after using isotopes of surface air, water and plants in the environment around the wellhead, the monitoring results were compared before and after the isotopes were used. Results showed that the radioactivity (P> 0.05). The maximum air dose rate of gonadal site of the operator was 69.84 · 10 -6 Gy · h -1.
