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...

2007:15 Transparensforum om mobiltelefoni –utbyggnaden av 3:e generationensmobiltelefoni i Sverige
Projektet Transparensforum om mobiltelefoni har haft som syfte att förbättra dialogen i samhället avseende elektromagnetiska fält, med fokus på mobiltelefoniutvecklingen (3G), samt att öka förståelsen för olika aktörers roller. Metoden i projektet har varit RISCOM-modellen för riskkommunikation som bl.a. innebär att alla frågor måste...

2007:02e Radiation Environment in Sweden, summary
The radiation environment to which the population of Sweden is exposed is dominated by medical 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 within the field of radiation. The report shows that people’s behaviour in the form of...

1999:13 Determination of the Neutron and Photon Dose Equivalent at Work Places in Nuclear Facilities of Sweden
Various mixed neutron-photon fields at workplaccs in the containment of pressurised water reactors and in the vicinity of transport containers with spent fuel elements were investigated with spectrometers and dosimeters.The spectral neutron fluences evaluated from measurements with multisphere systems were recommended to be used for the calculation of dosimetric reference values for...

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...

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...

2005:61 Review and Assessment of SCC Experiments with RPV Steels in Oskarshamn 2 and 3 (ABB Report SBR 99-020)
Although the extent of cracking was rather surprising for a bolt-loaded specimen, the average stress corrosion crack growth rate of 0.5 mm/year over the five-year testing period does not represent an immediate concern. The overwhelming part of crack growth can have occurred during a 20 day chloride transient during the third year of exposure because of a condenser leakage after an outage. The...
