Radon exhalation rate is the of radioactive radon gas that escapes from soil into atmosphere. In this study was measured for 33 samples soil, in four districts Duhok province, using two different techniques: one concentration and other radium content, by both alpha gamma spectroscopy. For measurement, alpha-sensitive RAD7 detector used. While second method, expressed as a function concentration...

We examined differences in the radioactive characteristics among the main minerals forming granite materials. Using a non-toxic high-density agent, minerals were separated from rock (granite-gneiss) and soil (weathered granite) samples. The natural radioactivity ((238)U and (226)Ra) and radon emanation fraction of the minerals were then studied by gamma-ray spectrometry. The radon emanation fra...

The exhalation of geochemical entities from soil to air is significant understand Lithosphere-Atmospheric relationships. Some these are capable modifying the lower atmosphere, and they employed in various studies. Radon one gasses widely recognized as a dominant ionization source near ground regions troposphere. steady state Rn transport equation considered many cases for estimating migration o...
