2010:20 Lågfrekventa magnetfält i olika färdmedel – en studie baserad på mätningar från åren 1993-2010
Denna rapport sammanfattar resultaten från magnetfältsmätningar i olika färdmedel. Mätningarna genomfördes av Strålsäkerhetsmyndigheten, fd. Strålskyddsinstitutet, under åren 1993-2010. Mätningarna har gjorts inom ramen för myndighetens miljöövervakning på området elektromagnetiska fält. Syftet har varit att ge...

2010:13 Rapport från SSM:s vetenskapliga råd om ultraviolett strålning 2009
I denna rapport för år 2009 redovisas aktuella tidstrender för hudtumörer, sambandet mellan solarieanvändning och olika typer av hudcancer, att diskussionen om D-vitamin och cancerrisk inte bör sammanblandas med strategier för hudcancerprevention, aktuellt om säkerhetskrav på solskyddsmedel, läget för ozonskiktet och den naturliga UV-strålningen,...

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 be caused by UVB radiation. However, recent studies show that UVA and UVB can give rise to similar DNA damages in human skin. Because of the potentially greater exposure to UVA while using...

2020:12 Assessment of the QT-COOL coolant channel module against the PBF RIA 1-2 experiment
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 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...

2020:07 Fibre Clogging in Nuclear Power Plants
SSM perspective Background Emergency core cooling systems in boiling- and pressurized water reactors use strainers. Their purpose is to out foreign material suspended in the cooling water so this material does not reach the reactor. After the 1992 event at Barsebäck nuclear power plant when the strainers of the emergency cooling system was clogged due to fibers in the cooling water, all...

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...

2021:21 Region-specific radioecological evaluation of accidental releases of radionuclides from ESS
SSM perspective Background To strengthen the material science research in Europe, the European Spallation Source (ESS) is being built in Lund in the southern part of Sweden. In the spallation process, neutrons are generated when the accelerated protons hit the tungsten target. In addition, a broad range of radioactive by-products are produced that differs from the fission products produced in...

2021:01 In situ NMR condition monitoring of cable insulations in Nuclear Power Plants
SSM perspective Background As the nuclear power plants are ageing, it is important to verify that every component installed can function safely in the intended environment. Cables are among the most common components in a nuclear power plant and are required to function during normal operation as well as in the event of an accident. There is a need within the nuclear industry for...

2021:02 On Water Induced Sensitization of Ni (Fe,Cr) alloys towards Stress Corrosion Cracking in LWR Piping from 1st Principles Modelling
SSM perspective Background In Swedish Light Water Reactors (LWR), stress corrosion cracking of reactor components and welds occurs from time to time. As the nuclear power plants are ageing, it is essential to study and further understand the mechanism for environmentally induced sensitization. Natural cracking is a phenomenon that is difficult to predict and very hard to study since it occurs...
