4. Radon in Groundwater- Influencing Factors and Prediction Methodology for a Swedish Environment
Sammanfattning : This thesis presents a method for predicting radon (222Rn) levels in groundwater on a general scale, within an area of approximately 185 x 145 km2. The method applies to Swedish conditions, where 222Rn is the main contributor to natural radioactivity. LÄS MER
5. The radium distribution in some Swedish soils and its effects on radon emanation
Sammanfattning : The aim of this study has been to clarify how the radiumdistribution in soils affects the radon emanation. Thedistribution of radium, uranium and thorium has been determinedusing sequential extractions. In the study, soils from twodifferent locations were investigated. LÄS MER
