| 摘 要： | 目的:测定计算机视频终端的X射线剂量水平。方法:采用高灵敏LiF(Mg,Cu,P)热释光剂量计对计算机视频终端表面及其附加防护屏(网)后的辐射剂量进行累积剂量监测。结果:计算机视频终端表面的平均照射量率为2.40×10-7C·kg-1/d(0.93mR/d),在防护屏(网)外的平均照射量率是0.62×10-7C·kg-1/d(0.24mR/d)。结论:监测结果表明,计算机产生的低能和低水平电离辐射剂量未超过有关规定标准。

| Abstract: | Objective The measurement of low energy x ray dose emitted by video display terminals.Method Thermoluminescent dosimetry (TLD) has been used to determinate the radiation dose of the video display terminals (VDT) and the exposure in extra of radiation protection screen.Results The average exposure in VDT surface is 2.40×10-7C·kg-1/d (0.93mR/d).The exposure in extra of radiation protection screen is 0.62×10-7C·kg-1/d (0.24mR/d).Conclusion The measurement results show that the low-level and low energy ionizing radiation doses produced by VDT are not beyond the related regulations. |
