CONCENTRATION OF RADON IN SPRINGS OF KELBAJAR REGION, REGULARITIES OF ADSORBTION OF RADIONUCLIDES FROM SOLUTIONS ON ADSORBENTS

Abstract

Higher values of the total radiation and the intensity of alpha radiation were observed in soil areas around thermal and cold springs on the mountain slopes of the Kelbajar region of Azerbaijan. The concentration of radioactive radon in the water of the thermal springs of the “Istisu” sanatorium, located at an altitude (2203 m), is below the directive indicator. However, the concentration of radon in the water of springs, located at an altitude of 2385 m, exceeds the directive indicator by 100 times. Soil samples taken from areas around springs contain uranium isotopes in similar proportions found in natural uranium deposits. Regularities of sorption of uranium isotopes from aqueous solutions on some adsorbents have been studied. It has been established that weak Van der Waals forces exist between the absorbed isotopes and the adsorbents.
