  5. 4. Radon in Groundwater- Influencing Factors and Prediction Methodology for a Swedish Environment

    Författare :Kirlna Skeppström; Bo Olofsson; Per Erik Jansson; Jon Petter Gustafsson; Gerhard Barmen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radon; Grondwater; GIS; RV method; Multivariate statistics; Water engineering; Vattenteknik;

    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

  7. 5. The radium distribution in some Swedish soils and its effects on radon emanation

    Författare :Cecilia Edsfeldt; KTH; []
    Nyckelord :distribution; emanation; extraction; glacial till; podzol; Ra; radium; radon; Rn; sequential soil; spodosol; Th; thorium; U; uranium; variability;

    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
