• 2003:16 Radon in Estonian dwellings. Results from a National Radon Survey

  A countrywide survey of radon concentrations in Estonian dwellings was carried out during the period 1998-2001. The survey formed a part of the cooperation program on radiation protection between the Estonian Radiation Protection (Kiirguskeskus) Centre and the Swedish Radiation Protection Authority (SSI). The Estonian Environmental Foundation and the Swedish Ministry for Foreign Affairs have...

• 2003:14 Exchange processes at geosphere-biosphere interfaceCurrent SKB approach and example of coupled hydrological- ecological approach

  The design of the repository for final disposal of spent nuclear fuel proposed by SKB is based on a multi barrier system, in which the geosphere and biosphere are the utmost barrier surrounding the engineer barriers. This report briefly reviews the current approach taken by SKB to account for hydrological and ecological processes at the geosphere-biosphere interface (GBI) and their future...

• 2002:23 Validation of dose calculation

  This report describes a validation of the computer codes RESRAD-RECYCLE and CERISE, which are used to estimate radiation doses due to the recycling of scrap metal. Calculated external radiation doses to individuals are compared with measured data from different steps of the processing of slightly contaminated material, mainly in Studsvik, Sweden.
