Abstract: Recently, negative effects of UV and gamma radiation are one of the human concerns in each reign. Therefore, detection of UV and gamma threshold in different geographical areas, for possible radiation crises management in risk full reigns is necessary. Therefore, natural and manmade features effects on UV and gamma radiation was studied in Gonabad. In this sectional study, the effect of natural (latitude, longitude, height and climate conditions) and manmade (village, urban, road and others) features on UV and gamma radiations in Gonabad located in Khorasan Razavi, Iran were measured using an emanation method. Distance between each two stations was 5 Km. Results showed that the relationship between UV and gamma radiation with longitude was significantly negative. Also, the relationship between UV and gamma radiations with latitude was significantly negative (p<0.001) and no significant respectively (p>0.001). But climate condition (cloudy, semi cloudy and lightly) had significant (p<0.001) and no significant effect (p>0.001) on UV and gamma radiation, respectively. In addition, effects of natural and manmade features on UV and gamma radiations was significant (p<0.001) and no significant (p>0.001), respectively. At the end it was cleared that changes range of UV and gamma radiations was 0.464±0.2798 W/m2 and 0.1321±0.01936 msv. The results shown that the average of UV and gamma radiation in Gonabad are more than international mean value reported by UNSCEAR-2000.
