理论和实验均表明,各个地质构造内不同时间γ场的变化是由深部地质动力作用决定的。基于这样的理解,研究了乌兹别克斯坦某些地震活动构造的γ场。断裂位移区内γ放射性值的变化,较之褶皱构造,提高了一个数量级以上。根据放射性剖面测量的结果,在乌兹别克斯坦的各级活化位移系统以及地震震中区(M=5),均存在着区域性和局部性的γ场的持续的和可逆的变化。 Both theory and experiment show that the variation of γ-field at different times within each geological structure is determined by the deep geodynamic forces. Based on this understanding, the γ field constructed by some seismic activities in Uzbekistan has been studied. The variation of γ radioactivity in the fracture-displacement zone is more than an order of magnitude higher than that of the fold structure. Based on the results of the radiometric profiling, both the regional and local γ-fields have a continuous and reversible change in the active displacement system at all levels and the epicentral region (M = 5) in Uzbekistan.
