摘要
目的探讨碘-125植入术后放射暴露对病区护理人员血象影响,为改善护理人员放射防护提供依据。方法以接触碘-125植入术后的病区护理人员为实验组进行外周血象监测,与同一时期内无粒子植入病区护理人员(对照组)血象结果进行比较分析;另对碘-125植入术后患者当天在有铅衣覆盖和无铅衣覆盖的情况下,分别从不同角度和距离进行γ射线测得结果进行比较分析。结果外周血象指标结果显示实验组低于对照组,但差异无统计学意义(P>0.05);无铅衣覆盖的情况下,距离手术穿刺点100 cm测得放射剂量(10.6±2.6)uSv/h接近γ射线测量天然本底剂量,有铅衣覆盖情况下,距离15 cm测得放射剂量(10.4±2.0)uSv/h接近γ射线测量天然本底剂量。结论采用铅衣防护后,碘-125植入后放射暴露对病区护理人员外周血象无明显影响,能有效缩短安全放射距离。
Objective To explore the effect of radiation exposure after iodine-125 implantation on the blood indicators of nursing staff in wards,and to provide basis for improving the radiation protection of nursing staff.Methods Peripheral blood parameters of the nursing staff(experimental group)in the ward who were exposed to iodine-125 after implantation were monitored,and the blood parameters of the nursing staff(control group)in the ward without particle implantation during the same period were compared and analyzed.In addition,the results of gamma ray exposure from different angles and distances in patients after iodine-125 implantation were compared in conditions of lead shielding or lead-free shielding on the same day.Results The results of the peripheral blood parameters in the experimental group were lower than those in the control group(P>0.05).Under the condition of lead-free shielding,the radiation dose measured at a distance of 100 cm from the puncture site was(10.6±2.6)uSv/h,which was close to the natural background radiation dose measured byγ-rays. Under the condition of lead shielding,the radiation dose measured at a distance of 15 cm was(10.4±2.0)uSv/h,which was close to the natural background radiation dose measured byγ-rays.Conclusion After using lead shielding,post-implantation radiation exposure from iodine-125 has no significant impact on the peripheral blood parameters of the nursing staff in the ward and can effectively reduce the safe radiation distance.
