Background: The health implication of exposure to gamma radiation in the outdoor and indoor environments has become a major concern worldwide. Methods: This study was conducted in the city of Birjand where three stations and buildings were randomly selected to measure the background radiation in outdoor and indoor places; for this purpose, GM detector (X5C plus) was used. All dose rates on the display of the survey meter were recorded, and the mean of all data in each station and buildings was computed and taken as the measured dose rate of that particular station. Results:The average dose rate of background radiation was 71.8 nSv/h for outdoor and 82.0 nSv/h for indoor environments, and the maximum and minimum dose rates were 79.6 nSv/h and 61.7 nSv/h for outdoor measurements and 112.9 nSv/h and 70.8 nSv/h for indoor measurements, respectively. Conclusions:The results revealed that the annual effective dose is 0.49 mSv, which is similar to that of the global level (0.48 mSv).

The estimated excess lifetime cancer risk was 1.715 × 10-3 , which was high compared to the world average value of 0.25 × 10-3 .

“…Many studies in this field are focusing on the measurements of radioactivity concentrations to determine the areas of high levels and correlation between radioactivity in soil and non-radioactivity in soil and geological structure of areas under study (Kannan et. Al, 2002;Matiullah et al, 2004;El-Arabi, 2005;Sahoo et al, 2011;Rashed-Nizam et al, 2015;Idriss et al, 2016;Nkuba et al, 2017;Ribeiro et al 2018). In Sudan, there are some previous research conducted to study the radioactivity concentrations of 238 U, 232 Th and 40 K in various environmental compartments (Osman et.…”

This work was carried out with the aim to establish baseline data of soil radioactivity prior commissioning the first nuclear power plant for electricity production in the Sudan. A total of 105 soil samples from the proposed area were collected and analyzed using Gamma-ray spectrometer, X-ray Fluorescence and Atomic Absorption. Ambient dose rates were measured during sampling using radiation survey meters. Based on radionuclides in soil; some radiological hazard indices (such as absorbed dose rates, Radium-Equivalent Activity, External Hazard, and Gamma index) were computed. The results exhibit that226Ra, 232Th,40Kand 137Cs concentration ranged from0.55-88.9, 1.63-76.6, 24-1100 and 0.001-1.03 Bq/kg with an average value of10.43, 11.12, 361.2and 0.045Bq/kg respectively. The average value of absorbed dose rate(29.92nGy/h), Radium equivalent (70.55 Bq/Kg), external hazard (0.19), Gamma index. (0.25) and those parameters are lower than the corresponding global average. The results of the study revealed that the average values of 226Ra, 232Th, 40K and 137Cs fall within the global average value. GIS Predictive exhibited the spatial distribution of radioactivity trends with low levels at eastern part towards the Red Sea while high values observed at the desert (western part). This trend in addition to low levels has a very good impact to decision makers for consideration in site selection of NPP. Pearson correlation coefficient shows a correlation between the variables 226Ra and 232Th (0.69); Cr and Au (0.82); Br and Nb (0.84),Hf and Sb (+0.75) with no significant correlations between radioactive and radioactive elements. Keywords: Road map, GIS, Gamma-ray Spectrometer, Effective dose.
