Abstract :

The most important radioactive elements of the crust are uranium and thorium. Different isotopes of these elements become stable elements with long decay chains and the production of other radioactive elements. The Shirkuh granite batholith, with a partial melting origin, extends over a thousand square kilometers, from chronology to early geological formations to the present day. According to the measurement of radionuclides in water, soil and rock, Shirkuh granite has U and Th radioactive elements. Landsat satellite images are used to study the Shirkuh in terms of radioactive elements distribution. Also, 30 kinds with the number of radioactive elements identified by Field Spec were sampled and spectral libraries were designed. In this study, the areas with the highest concentration of radioactive elements were determined using spectral angle mapping and supervised classification. The results show that the highest uranium and thorium specimen are located in three regions: west and south of Manshad and south of Tabriz
