摘要

本文采用航空伽马射线光谱技术对叙利亚Ar Rassafeh Badyieh地区（Area-2）的放射性产热进行了评估。对于热生产HP参数，已经分别对区域-2的九个已建立的岩性评分单元进行了表征。提出了浓度数（C-N）模型和与分形技术相关的对数-对数图，并将其作为绘制Area-2测量的当量铀（eU）、当量钍（eTh）和当量钾（K%）以及计算的产热（HP）的新方法。区域-2的HP在最小0.06和最大4.28之间变化？w/m3，平均0.548？w/m3，标准偏差为0.27？观察到的最高HP值与由两个岩性评分单元A和B代表的磷酸盐环境有关。

Radioactive heat production characterization of Ar-Rassafeh Badyieh area (area-2), Syria by using aerial gamma ray spectrometric and fractal modeling techniques

Aerial gamma-ray spectrometric technique is used herein to evaluate the radioactive heat production (HP) of Ar-Rassafeh Badyieh Area (Area-2), Syria. The nine already established lithological scored units of Area-2 have been separately characterized for the heat production HP parameter. The Concentration-number (C-N) model and the log-log plots associated with fractal technique are proposed and applied as a new approach to map the measured equivalent uranium (eU), the equivalent thorium (eTh), and potassium (K%) and the computed heat production (HP) of Area-2. The HP of Area-2 varies between a minimum of 0.06 and a maximum of 4.28 ?w/m3 with an average of 0.548 ?w/m3 and a standard deviation of 0.27?w/m3. The highest observed HP values are related to the phosphatic environments represented by two lithological scored units A and B.
