A methodology that extends the usability of low and medium resolution γ-ray detectors to a wide range of energies that appear in environmental radioactivity measurements is described. Results of the implementation of the methodology in the analysis of 20 granite samples measured with a (3″ × 3″) NaI(Tl) are presented. A comparison with the activity results obtained by a high-resolution detector (HPGe) for two samples was found in good agreement, within the uncertainties, validating the results of the proposed method.
描述了一种将低分辨率和中分辨率γ射线探测器的可用性扩展到环境放射性测量中出现的广泛能量范围的方法。给出了该方法在用(3″×3″)碘化钠（铊）测量的20个花岗岩样品分析中的实施结果。发现与用高分辨率探测器（高纯锗）对两个样品获得的活度结果在不确定度范围内具有良好的一致性，从而验证了所提方法的结果。
