Introduction to β - γ Core Recorder:

β - γ Core RecorderIt is used to measure the uranium radium balance of rock cores (ore cores), especially in areas with biased uranium where the uranium radium balance is disrupted, which can effectively prevent ore leakage. The detector adopts plastic crystals and photomultiplier tubes, with high sensitivity; Integrated design with the console, portable and practical; It has data storage and playback functions, and a standard USB communication interface. Complies with the industry standard EJ/T 757-93 "Sampling and Recording Standards for Gamma Radiation in Uranium Mines".
