A STUDY AND ITS APPLACATION OF URANIUM ISOTOPE IN UNDERGROUND AND SURFACE WATER FROM LIANGCHENG AREA,SUOTHERN SHANDONG PROVINCE
鲁南两城地区水的铀同位素研究及其应用

Determination of uranium isotope contents has been made by the method of radioactive disequilibrium between 234U and 238U for the surface and underground water from Liangcheng region of southern Shandong Province, and the results of 30 water samples analyses are presented.These results show that the underground water has three sources, namely deep karst, shallow porous and surface waters. The uranium isotopic compositions of water are quite stable, and the mixing ratio of water body has been used to evaluate the amount of water resource in considered area.The results of calculation is of the same with those obtained by other regular method.
