The radiological effects from 21 soil samples collected from Wadi Nasib area of approximately 40 Km2, Sinai, Egypt, were measured using gamma spectrometer. CR-39 plastic track detector was used for radon exhalation rate measurements employing (closed can technique ). The uranium concentrations were also measured for these samples as well as radium equivalent concentrations. The obtained results show: The radon exhalation rates were found to vary from 1.48 to 63.36 Bq m−2 h−1. Uranium concentration varies from 1 to 89 ppm, whereas Radium concentration in soil samples has been found to vary from 2 to 114 ppm. The radon levels at the depths of 1 m are nearly twice the levels at 0.5 m in the experimented area. The rate of radon diffusion is found to depend mainly upon medium porosity. The annual effective dose measured for this area exceeds the permissible values, recommendations and precaution should be undertaken during any exploration processes in this area
