    • The present invention relates to a method of determinating an exposure rate of individual gamma nuclide. The method includes converting an energy spectrum with respect to the count rate into an energy spectrum with respect to an exposure rate by using a G-factor of a detector to provide exposure rate information of a gamma nuclide; calculating a net area of a photo peak reflecting the exposure rate, which results from a photoelectric effect, from the converted energy spectrum to derive the exposure rate resulting from the photoelectric effect of the individual gamma nuclide; and determining a total exposure rate of the individual gamma nuclide by calculating a peak-to-total ratio, which represents a ratio of the exposure rate resulting from the photoelectric effect to a total exposure rate, and the exposure rate resulting from the photoelectric effect of the individual gamma nuclide. Thus, the exposure rate of each gamma nuclide can be accurately calculated.
    • 本发明涉及确定单个γ型核素的曝光率的方法。 该方法包括通过使用检测器的G因子将相对于计数率的能谱转换成相对于曝光率的能量谱,以提供γ核素的曝光率信息; 从转换的能谱计算反映由光电效应产生的曝光率的光峰的净面积,以导出由各个γ核素的光电效应产生的曝光率; 并且通过计算表示由光电效应产生的曝光率与总曝光率的比率的峰 - 总比率以及由光电效应产生的曝光率来确定单个伽马粒子的总曝光率 单个γ核素。 因此,可以精确地计算每个γ核素的曝光率。
