Dependence of radon exhalation on grain size of sedimentary waste
Tailings resulted from sulphuric acid leaching process of uranium from sedimentary rocks contain high concentrations of 226 Ra and its daughters, the most important of which is 222 Rn. Movement of radon gas out of the tailings is strongly influenced by the physicochemical characteristics of these ta...

Rn. Movement of radon gas out of the tailings is strongly influenced by the physicochemical characteristics of these tailings especially their radium content and the grain size. So, the tailing samples were size fractionated into four sizes (> 250, 250–125, 125–74 and 250 and |
