2007:02e Radiation Environment in Sweden, summary
investigations and background radiation from the ground and building materials in our houses. That is the conclusion of the first general Swedish summary of environmental monitoring data and dose calculations ... field of radiation. The report shows that people’s behaviour in the form of their exposure to the sun and smoking has a major impact on the risk of suffering radiation injuries. The radiation dose received...

2007:03 Variability and Uncertainties of Key Hydrochemical Parameters for SKB Sites
An important part of the site investigations conducted by the Swedish Nuclear Fuel and Waste Management Company (SKB) is the characterisation of groundwater chemical conditions in the deep bedrock environment ... the two candidate sites, Forsmark and Laxemar, and should be completed by the summer of 2007. It is essential that the information which is gathered is of high quality and representative of conditions in...

2007:12 Development of a constitutive model for the plastic deformation and creep of copper and its use in the estimate of the creep life of the copper canister
the Swedish Programme has a design life exceeding 100,000 years. Whilst the operating temperature and operating stress are modest, the very long design life does require that the likely creep performance ... ductility at the canister operating temperatures. A previously developed model for the plastic deformation and creep of copper (included as an Appendix to the present report) has been used as the basis for a discussion...
