目的:探讨血液辐照仪的辐射防护及样品辐照区剂量分布情况。方法:选用C-3001型和XHBRI-1000型血液辐照仪为研究对象,使用环境X、γ剂量率仪对辐照与非辐照状态下辐照仪外表面辐射剂量水平进行测量;以LiF(Mg、Ti)热释光元件为探测器,布放于辐照杯内不同层面,辐照后进行数据测读,探讨辐照杯内不同位置的剂量分布。结果:两种型号血液辐照仪在静止(关机)状态下,其外表面辐射剂量率最大值分别为0.30μGy/h和0.60μGy/h,工作状态(辐照)最大值分别为0.62μGy/h和0.28μGy/h。辐照杯内不同位置的辐照剂量值分布:C-3001型中层>顶层>底层,外围>中心;XHBRI-1000型顶层>中层>底层,中心>外围。辐照剂量偏差分别为-6.7%~10.4%和3.7%~17.5%。结论:两台血液辐照仪的辐射防护水平符合国家相关标准要求,辐照杯内不同层面辐射剂量分布较均匀。

Objective: To investigate the radiation protection level of blood irradiator and radiation dose distribution in radiation region of sample. Methods: The radiation dose levels of the two types of blood irradiators (C-3100 and XHBRI-1000) were measured at ON or OFF status with X,γdose rate instrument. The thermo-luminescent dosimeter LiF (Mg, Ti) detectors were placed in different position of the sample cup to measure the dose. Results:The maximum radiation dose rates at outer surface for C-3100 and XHBRI-1000 units were 0.30/0.62μGy/h and 0.60/0.28μGy/h at OFF/ON status, respectively. The radiation dose level declined from middle, top, to bottom, and from peripheral to center in the sample cup for C-3001 type with the radiation dose deviation of-6.7%~10.4%, differently, the radiation dose level declined from top, middle, to bottom, and from center to periphery in the sample cup for XHBRI-1000 type with the radiation dose deviation of 3.7%~17.5. Conclusion:the radiation protection level of two types of blood irradiators meted the relevant national criterions. The irradiations in the cup were relatively uniform distributed.
