Natural gamma ray well logging technique is used to characterize the radioactivity (GR) laterally and vertically in Banting district, SW of Malaysia. Seven drilled boreholes, along N–S profile with their natural gamma ray records are utilized to compute the heat production (HP) parameter, based on the Bucker and Rybach relationship.The analysis of 3467 measured points in those boreholes indicates that GR varies between 6.24 API and 358.4 API with an average of 79.95 API, while HP varies between 0.086 and 5.65 μw/m³ with an average of 1.25 μw/m³.The multi-fractal Concentration-Number (C–N) is used to characterize the radioactivity and heat production variations and to isolate different GR and HP populations in the study region. The high radioactivity and heat production ranges are mainly related to the silty clay layers, accompanied by uranium and thorium.

天然伽马射线测井技术用于表征马来西亚西南部万津地区的横向和垂直放射性。根据Bucker和Rybach关系，沿着N-S剖面及其自然伽马射线记录，钻了七个钻孔，用于计算热量（HP）参数。对这些钻孔中3467个测量点的分析表明，GR在6.24之间变化API和358.4 API，平均为79.95 API，而HP在0.086和5.65μw/ m ³之间变化，平均为1.25μw/ m ³。多重分形浓度数（C–N）用于表征放射性和热量产生变化，并分离研究区域中不同的GR和HP种群。高放射性和高产热量范围主要与粉质粘土层有关，并伴有铀和th。
