  • 2021:12 Magnetfält runt nätstationer

    SSM perspektiv Bakgrund Transformatorstationer (TRAFO) kan i sitt närområde ge starkt förhöjda magnetfält. Ibland placeras sådana stationer relativt nära bostadsmiljöer och även stationer placerade i bostadshus förekommer. De stationer som placeras på detta sätt är stationer som ger en spänningstransformation från ca 11...

  • 2021:03 Updated radiological risk assessment for the “Radon” type surface disposal facility in Chisinau, Moldova

    SSM perspective Background Bilateral cooperation between Sweden and the Republic of Moldova in nuclear and radiological safety and security has been ongoing since 2010, focusing on activities aimed at strengthening the institutional capacity of the National Agency for Regulation of Nuclear and Radiological Activities in Moldova (NARNRA) as well as infrastructure development in radioactive...

  • 2022:08 Geophysical surveys on sub marine land- and rock slides and on alpine glaciers

    SSM perspective Background The future climate evolution and the impact it might have on a repository for radioactive waste is important when assessing the long-term safety. In a project funded by SSM (Holmlund et al. 2016), bathymetric data from the Southern Quark area between Sweden and Åland, provided by the Swedish Maritime Administration, were analysed, as well as terrestrial data from...

  • 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 determined by the 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...

  • 1993:11 Methods for determination of strontium -90 in food and environmental samples by Cerenkov counting

    The procedure for determination of strontuim-90 (=yttrium-90) by HDEHPextraction of yttrium-90 and counting the Cerenkov radiation in a liquid scintillation counter, is applicable for all kind of samples. Prior to analyses liquid samples are evaporated to dryness and ashed. Environmental and food samples are oven dried and ashed. The ash is dissolved in 1 molar hydrochloric acid and, at pH...

  • 2019:03 Evaluation of the hydrodynamic model in PARET/ANL

    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 light water reactors. The Swedish Radiation Safety Authority (SSM) has access to SCANAIR in exchange for annual contributions for its further development. This ensures a possibility for SSM to do...

  • 2019:23 Participation in the European Committee for Standardization's workshop regarding civil structures

    SSM perspective Background During the period 2014-2018, a CEN1 workshop (Phase 2 Prospective Group 3 civil works) have been carried out. The aim of the workshop is to provide a base founded on the French standard in order to be able to establish a possible future European standard for the design of civil structures at nuclear power plants. The workshop has identied which additional...

  • 2023:12 Investigation of the limits of detection for specific radionuclides in soil from the European Spallation Source (ESS) using radiometric and mass spectrometric methods

    SSM perspective Background In Lund, the construction of the European Spallation Source (ESS) research facility is underway and the facility is also undergoing a stepwise licensing procedure in accordance with relevant legal requirements. At ESS, neutrons will be produced by spallation when high-energy protons from a linear accelerator hit a rotating tungsten beam target. The neutrons released...

  • 2024:03 Tillsyn och intervjuer på distans – Tekniska möjligheter och behov av socialt samspel

    SSM perspektiv Bakgrund I samband med de restriktioner som 2021 infördes till följd av corona-pandemin ställde SSM in besök på plats hos verksamhetsutövare och ersatte en del av dem med ”tillsyn på distans”, främst som möten eller intervjuer med hjälp av videosamtal. Redan tidigare har SSM genomfört delar av tillsyn på distans, då...
