Abstract

Background and Objective: Radiation survey has been carried out at a wonderland of Blue Nile shore of Khartoum state as a protective and safety precautions for community. The objective was to assess the radiation exposure level and the committed dose by public compared with authorized one. Materials and Methods: the method used was an experimental survey covering 10 km² using Geiger Muller survey meter at surface and depth profile down to 100 cm with enhancement of hoe and drill for deeper samples that consists of 90 samples. The Results: the analyzed data showed that: the emitted radiation represented γ-radiation and particles as (β and α). The exposure level at surface due to γ- radiation and particles was 0.21μSv/h that represents 0.021% of the maximum permissible dose for public. The committed dose by the entertained public at wonderland areas based on the number of trips was 40.3 μSv/year; at surface which is equivalent to 4.03% of the MPD due to γ-ray, α and β particles irradiation. The exposure dose was found to be increased following the depth increment based on equation: y = 0.114e^0.003x, where x refers to depth in centimeter and y refers to exposure in μSv/h. And at depth 100 cm; the exposure level was 0.17 μSv/h due to γ-ray, α and β particles and 0.14 μSv/h due to pure γ-radiation respectively. Conclusion: the study revealed considerable exposure level to frequent entertained public at Blue Nile shore in Khartoum beside Tooti city boundary.
