Assessment of Radiation Dose Level at Blue Nile Shore inTutiIsland

Abstract

exposure level of radiation at the Blue Nile river shore in Khartoum state during April 2012. The monitoring of radiation was carried out using Giggler Muller survey mater covering a distance of 50 m where people usually entertain themselves and chatting. The ultimate goal of this study was to estimate the radiation dose level and radioactivity at the Blue Nile bank and increase the culture of the radiological safety as well as concept of radiation protection .the results showed that the radioactivity is under below the natural radioactivity background at all different point. The surface dose was 0.05Sv/h for all points and the dose increases with depths at 25, 50 and 75 cm to be 0.089, 0.11, 0.12 and 0.13Sv/h respectively. The average exposure increases from 0.05Sv/h at the surface to 0.07Sv/h at 25 cm, 0.09 at 50 cm and 0.1 Sv/h at 75 cm. The average exposures per year were 7.78, 10.43, 12.67 and 14.78Sv at the surface, 25 cm, 50 cm and 75 cm respectively.
