2012:02 Evaluation of activity build-up experiments
the water chemistry affects the activity build-up on surfaces in different systems in Swedish nuclear power plants, which in turn provides information on conditions required to reduce the radiation exposure ... The effects on the activity build-up from iron, nickel and zinc ions were studied. The metal oxides formed were also studied with high-resolution microscopy to provide further information on the progress...

2022:13 Long-time variations of radionuclides and metals in the marine environment of the Swedish west-coast studied using brown algae
(Fucus serratus and Fucus vesiculosus) SSM perspective Background The marine environment receives discharges from nuclear facilities around the world as well as in Sweden. The brown seaweeds, Fucus serratus ... thereby usefulness in environmental monitoring as a bio indicator. Bio indicators provide information on levels and variations of elements, like for example radionuclides, in the marine environment. By studying...

2010:41 Rock-block configuration in Uppland and the Ålands-hav basin, the regional surroundings of the SKB site in Forsmark, Sea and land areas, eastern Sweden
Swedish Radiation Safety Authority (SSM). The conclusions and viewpoints presented in the report are those of the authors and do not necessarily coincide with those of the SSM. The topography in Uppland is more ... more broken in the sea area east and northeast of Forsmark than it is on land. The major structure in the Ålands-hav basin is a west-north-westerly line that passes southwest of Åland, with a very steep...

2013:30 Laser pointers and Eye injuries - An analysis of reported cases
little information on what tissue damages that may be expected at various elevated exposure levels. Similarly, the Swedish Radiation Protection Authority (SSM) has very little information on how such tissue ... disability is very useful in the risk assessments that are made in the authority’s supervision activities. Also, the damage’s evolvement over time is information that the authority can make use of in risk...

2022:09 Assessment of modelling approaches for axial gas flow inside LWR fuel rods
SSM perspective Background The fuel rod analysis program SCANAIR has been developed by IRSN (Institut de Radioprotection et de Sûreté Nucléaire) for analysis of reactivity initiated accidents (RIA) in ... Authority (SSM) has access to SCANAIR in exchange for annual contributions for its further development. The development and administration of the program is done by Quantum Technologies AB on assignment...

2011:11 Handling Interfaces and Time-varying Properties in Radionuclide Transport Models
Quintessa’s QPAC code has been used to investigate the Qeq approach. The conclusions from this simulation study are the following. The basic approach to calculating Qeq values is sound, however, narrow ... the potential to increase the release significantly. Quintessa’s AMBER software has been used to explore the effects of glacial episodes on radionuclide transport with time-varying properties. The simulation...

2013:07 Corrosion of copper in distilled water without molecular oxygen and the detection of produced hydrogen
this was not possible in the experimental set-up used. Thus it cannot be excluded that formed species on surfaces could have been altered during handling of specimens between exposure and surface analysis ... indicate that the reaction products are predominately comprised of oxide and hydroxide. Furthermore, based on the visual appearance, the reaction products formed are solid and of a three dimensional character...

2009:24 UV-radiation induced disease – roles of UVA and UVB
There is a large uncertainty concerning the impact of UVA and UVB radiation on the skin and eye. For example, UVA radiation used to be considered low risk since it was believed that DNA damage could only ... potentially greater exposure to UVA while using sunbeds or UVB-blocking sunscreens, further information on the role of UVA is crucial. It constitutes a necessary foundation for the authority for its recommendations...
