The most promising devices of those for radionuclide diagnosis that can be used for control of nuclides incorporated in the human body during a radiation incident are hybrid scanners. The authors made the calibration of devices of this type to register a mixture of 137Cs and 134Cs. The minimum detected activity was 40 nCi. A methodological error of measurements was +/- 3%. A mathematical criterion for optimization of the geometry of measurements was drawn for devices, including the methodological and statistical components of a total error. This criterion was used for finding optimum sizes of a slot collimator of the device.
在放射性核素诊断设备中，最有前景且可用于在辐射事件期间控制人体中所含核素的设备是混合扫描仪。作者对这类设备进行了校准，以记录137Cs和134Cs的混合物。最小检测活度为40 nCi。测量的方法误差为±3%。为设备绘制了测量几何形状优化的数学标准，其中包括总误差的方法学和统计成分。该标准用于确定设备狭缝准直器的最佳尺寸。
