Nowadays geophysical airborne data have high importance for radioactive mineral exploration. In fact these data is major base for radioactive elements exploration. In this study by airborne radiometric data interpretation collected from Hashtrod 1:100000 sheet no. 5464 situated in north Iran expectation areas for uranium, thorium and potassium were recognized. Firstly, statistical parameters were calculated and radiometric elements' histograms of the area were drawn using conventional statistics. Moreover, promising maps were drawn based on the dispersion around the mean. Then, concentration- area full logarithm plots were drawn by using fractal method and digit data collected in the area. Next, plots associated uranium, thorium and potassium anomalous areas were prepared after step separation of different environments (background, threshold, anomaly) had been done based on C-A angular coefficient curve. The correlation coefficients between These elements were determined after some tables of data scattering were drawn. The image Ternary radioelement map color space GRB earns in the region and finally to process the images and extract the most important forms of uranium anomalies identified hot area and the introduction of promising deposits of radioactive minerals indexes were examined for discovery proceedings

Narigan area is located in Bafgh-Saghand metallogenic zone on Iran plateau. There are some anomalyradioactive elements which can penetrate into the soil, plant roots, plant textures and animal bodies. On the otherhand, these anomaly radioactive elements can effect animals by emitting dangerous rays. During this research forenvironmental studies in Narigan area, after determining plants and animal viodeversity, 15 samples were chosenfrom plant bodies and the soil around them. Radioactive elements were measured by (HPGs) device. Accordingto the analysis results, most of the samples contain large amounts of radioactive elements such as: Ra226, U, andCs137and K40 which are a risk for environment of this area. Due to the studying of plants and soil samples,Astragalus can be used as geo botanical indicator for U and Th elements in this area.

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
