• 2012:22 A dosimetric intercomparison between the radiation therapy clinics in Sweden

  In general the study showed a good agreement between the results from the audit team and the local team. The examination of the reference dosimetry showed an excellent agreement between the absorbed dose ... audit team and the local team. The spread of the results among the Swedish radiotherapy departments was much lower as compared to similar studies conducted in other countries. SSM believes that this is...

• 2012:61 Geochemical Constraints on Buffer Pore Water Evolution and Implications for Erosion

  Mineralogical data from the Forsmark Site show that smectite and calcite occur at all depths in Forsmark fractures, with no evidence for removal/dissolution by previous glacial episodes.  This natural analogue ... groundwaters are in equilibrium (steady-state) with montmorillonite and saponite and these minerals may control pH, PCO2, SiO2(aq) and Na/Ca in groundwaters (and any future intruding glacial meltwaters) in the near-field...

• 2012:07 Implementation of the Master Curve method in ProSACC

  Cleavage fracture toughness data display normally large amount of statistical scatter in the transition region. The cleavage toughness data in this region is specimen size-dependent, and should be treated ... methodology is a procedure for mechanical testing and statistical analysis of fracture toughness of ferritic steels in the transition region. The methodology accounts for temperature and size dependence of fracture...
