2014:51 Report from SSM’s scientific council on ionizing radiation within oncology, 2013. MR in radiotherapy - an important step towards personalised treatment?
Imaging is important for radiotherapy and the development of new imaging modalities is closely linked to the evolution of modern radiotherapy. The implementation of magnetic resonance imaging (MRI) in modern radiotherapy holds great promise for the future but the scientific council emphasizes that it must be carefully monitored in order to minimize the introduction of new risks,...

2013:31 Aesthetic ultrasound devices – current state of knowledge and suggested measurement set-up for characterization of exposure
This report concerns the ultrasound devices used for the aesthetic purposes of body contouring and fat reduction (ablation of adipose tissue). Such devices have recently become more frequent on the Swedish market. These ultrasound devices are currently not medically regulated in Sweden and little is known about their safety and potentially harmful exposure when using them. This report aims to...

2013:30 Laser pointers and Eye injuries - An analysis of reported cases
The safety limits that exist for human exposure of laser radiation are essential to reduce the risk of injuries. These values, however, give very 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 damage is related to the impairment of the...

2012:04 Förslag till nationell modell för klinisk revision av strålbehandlingsverksamhet
Denna rapport innehåller en beskrivning av en nationell modell för klinisk revision av strålbehandlingsverksamhet i Sverige och konsekvenserna av dess införande. Rapporten vänder sig främst till beslutsfattare på olika nivåer inom statsförvaltningen och landstingen: politiker, tjänstemän och verksamhetschefer. Den bidrar också med kunskap...

2012:02 Evaluation of activity build-up experiments
This project aims to understand how 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 to power plant staff. The study was done to obtain knowledge about water chemistry conditions preferred to minimize the activity build-up. A number of...

2009:36 Recent Research on EMF and Health Risks. Sixth annual report from SSM:s independent Expert Group on Electromagnetic Fields 2009
A large number of cell studies are done on both genotoxic and non-genotoxic outcomes, such as apoptosis gene expression. There are no new positive findings from cellular studies that have been well established in terms of experimental quality and replication. Potential heating of the samples is still seen as a major source of artefacts. Moreover, these few positive results are not related to...

2008:14 SSI:s roll i folkhälsoarbetet 2008 – redovisning av regeringsuppdrag inom folkhälsoområdet
Rapporten är en redovisning till regeringen och Statens folkhälsoinstitut av myndighetens roll inom folkhälsoområdet. Strålskydd är i sig en förebyggande verksamhet som syftar till att skydda människor och miljö mot skadlig verkan av strålning. SSI menar därför att merparten av myndighetens arbete är folkhälsorelaterat. I rapporten...

2008:09 The Generalised Ecosystem Modelling Approach in radiological assessment
An independent modelling capability is required by SSI in order to evaluate dose assessments carried out in Sweden by, amongst others, SKB. The main focus is the evaluation of the long-term radiological safety of radioactive waste repositories for both spent fuel and low-level radioactive waste. To meet the requirement for an independent modelling tool for use in biosphere dose assessments,...

2008:07 Modelling of long term geochemical evolution and study of mechanical perturbation of bentonite buffer of a KBS-3 repository
PART I: The Swedish Nuclear Fuel and Waste Management Co. (SKB) has recently completed a safety assessment project named SR-Can, related to the KBS-3 disposal concept. In this concept, the waste packages are surrounded by a buffer made of either MX-80 or Deponit CA-N bentonite. Interactions between the buffer and groundwater may modify the buffer composition and thus its containment...
