    Abstract: In this work, we are presenting the results of radium concentration, surface and mass radon exhalation rates for a number of 209 soil samples collected from different locations of Kassala town, Sudan, by using the can technique, containing CR-39. The values of radium concentrations from soil samples were found to be ranging from 3.9 to 34.2 Bq.kg-1... Show More
