自制90Sr保持架在皮肤病敷贴治疗中的辐射防护作用

Effects of self-made 90Sr applicator retainer on radiation protection in treatment of skin disease

    摘要
  • 摘要:
    目的 探讨自制90Sr敷贴器保持架使用前后敷贴室工作人员接受放射剂量和健康状况的变化情况及其意义。
    方法 采用自制90Sr敷贴器保持架代替传统手工操作，工作人员隔窗观察治疗。同时收集敷贴室工作人员个人年剂量当量及外周血白细胞总数和淋巴细胞染色体畸变率等数据，对比分析90Sr敷贴器保持架使用前后以上数据的差异。
    结果 90Sr敷贴器保持架使用前工作人员接受的放射剂量明显高于使用后（t=11.40，P＜0.01），使用前工作人员外周血白细胞总数明显低于使用后（t=-3.75，P＜0.01）。
    结论 自制90Sr敷贴器保持架的使用显著降低了医护工作人员的个人年剂量当量，提高了其外周血白细胞总数，保护了其身体健康。

     

    Abstract:
    Objective To investigate the effects of self-made 90Sr applicator retainer on reducing radiation doses to medical personnel and improving their health status.
    Methods Self-made 90Sr applicator retainer was used in radiation therapy instead of traditionally holding the applicator in hand.The individual annual dose equivalent, peripheral white blood cell count and lymphocyte chromosome aberration rate of medical personnel before and after the application of 90Sr applicator retainer were analyzed comparatively.
    Results The individual annual dose equivalent was significantly reduced after the application of 90Sr applicator retainer(t=11.40, P < 0.01). The peripheral white blood cell count was significantly improved after the application(t=-3.75, P < 0.01).
    Conclusions The application of 90Sr applicator retainer significantly reduced individual radiation doses, improved peripheral white blood cell count and effectively protected the health of medical personnel.
