Abstract :
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.
