The effective dose obtained by a patient on X-ray diagnostic studies may be determined by the Russian and foreign devices that measure the product of the absorbed dose by the radiation area while using the transition factors presented. They are calculated by the published data on the surface and effective doses per exposure unit, which are obtained on the phantoms by thermoluminescence dosimetry by taking into account the area of radiation, anode voltage, and projection, which characterize the standard conditions for performing basic X-ray diagnostic studies of adults and children (5 age groups). In the anode voltage range 40-120 kV, the factors are 10(-4) to 2.10.cm2) with errors of about +/- 32%.
患者在X射线诊断研究中获得的有效剂量可由俄罗斯和国外的设备确定，这些设备在使用所给出的转换因子时测量吸收剂量与辐射面积的乘积。它们是根据已发表的关于每次曝光单位的表面剂量和有效剂量的数据计算得出的，这些数据是通过热释光剂量测定法在人体模型上获得的，同时考虑了辐射面积、阳极电压和投影，这些参数表征了对成人和儿童（5个年龄组）进行基本X射线诊断研究的标准条件。在40 - 120 kV的阳极电压范围内，这些因子为10(-4)至2.10.cm2，误差约为+/- 32%。
