测定计算机显示器的X线辐射剂量

Measurement of Levels of X-ray Radiation Emitted From Computer Video Display Terminals

[目的 ]测定计算机显示器的 X线剂量水平。 [方法 ]采用高灵敏 L i F ( Mg,Cu,P)热释光剂量计对计算机显示器表面及附加防护屏 (网 )后的 X线辐射剂量进行累积剂量监测。 [结果 ]计算机显示器表面的平均照射量为 0 .93 m R/ d。在防护屏 (网 )外的平均照射量是 0 .2 4 m R/ d。 [结论 ]计算机产生的低能和低水平

To measure the levels of X ray radiation emitted from computer video display terminals Accumulative doses of X ray radiation emitted from the surface of terminal screen and radiation protcetive screen were measured by highly sensitive LiF(Mg,Cu,P) thermoluminescent dosimetry The average levels of X ray radiation emitted from the surface of terminal screen and radiation protective screen were 0 93 mR/d and 0 24 mR/d respectively [Conclusion]The low energy and low level X ray radiation emitted from the terminals didn′t exceed the related standards
