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 km<SUP>2</SUP> 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 ¦Ã-radiation and particles as (¦Â and ¦Á). The exposure level at surface due to ¦Ã- radiation and particles was 0.21¦ÌSv/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 ¦ÌSv/year; at surface which is equivalent to 4.03% of the MPD due to ¦Ã-ray, ¦Á and ¦Â particles irradiation. The exposure dose was found to be increased following the depth increment based on equation: y = 0.114e<SUP>0.003x</SUP>, where <i>x</i> refers to depth in centimeter and <i>y</i> refers to exposure in ¦ÌSv/h. And at depth 100 cm; the exposure level was 0.17 ¦ÌSv/h due to ¦Ã-ray, ¦Á and ¦Â particles and 0.14 ¦ÌSv/h due to pure ¦Ã-radiation respectively. <b>Conclusion:</b> the study revealed considerable exposure level to frequent entertained public at Blue Nile shore in Khartoum beside Tooti city boundary.},
