The principles of TRT and γ - ray digital scanning technology （GSDM） developed from TRT are introduced. The proprietary proto - type testing machine has been developed based upon the relations of γ - ray intensity attenuation with EDS, properties of materials for testing and material thickness. The proto - type testing machine is installed with ESD device, high - sensitivity probe, photoelectric duplex amplifier, program- controlled scanning unit and real -time processing computer. It is applicable for thickness measurement of high - temperature pipelines, thickness measurement of fouling in pipelines and furnace tubes as well as for on - line monitoring of high - temperature pipelines.
