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...

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...

2009:14 Review of Legislation and Regulatory Framework in Ukraine with Regard to Environmental Radiation Monitoring
This report was written in the frames of the development cooperation project in Ukraine entitled “Environmental Radiation Monitoring”. This report concerns a study which has been conducted for the Swedish Radiation Safety Authority, SSM. The conclusions and viewpoints presented in the report are those of the author/authors and do not necessarily coincide with those of the SSM. In 2006, the...

2008:12 Recent Research on EMF and Health Risks. Fifth annual report from SSI’s Independent Expert Group on Electromagnetic Fields, 2007
The report for 2007 is divided into four different frequency fields: static fields, extremely low frequency fields (ELF), intermediate fields (IF) and radiofrequency fields (RF). Recent volunteer studies have shown that movement in very strong static magnetic fields (>1T, used in magnetic resonance imaging) can induce electrical fields in the body and sensations of vertigo in some people and...

2008:08 SSI:s independent consequence calculations in support of the regulatory review of the SR-Can safety assessment
With the publication of the SR-Can report at the end of 2006, Swedish Nuclear Fuel and Waste Management Co (SKB) have presented a complete assessment of long-term safety for a KBS-3 repository. The SR-Can project demonstrates progress in SKB’s capabilities in respect of the methodology for assessment of long-term safety in support of a licence application for a final repository. According to...

2008:10 User’s manual for Ecolego Toolbox and the Discretization Block
The CLIMB modelling team (Catchment LInked Models of radiological effects in the Biosphere) was instituted in 2004 to provide SSI with an independent modelling capability when reviewing SKB’s assessment of long-term safety for a geological repository. Modelling in CLIMB covers all aspects of performance assessment (PA) from near-field releases to radiological consequences in the surface...

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...

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,...

2008:05 International Expert Review of SR-Can: Safety Assessment Methodology - External review contribution in support of SSI's and SKI's review of SR-Can
In 2006, SKB published a safety assessment (SR-Can) as part of its work to support a licence application for the construction of a final repository for spent nuclear fuel. The report represented the culmination of work conducted by SKB over several years, focusing on the goal of making the licence application in late 2009. Results from the SR-Can project have been documented in several...

2007:10 Radiological consequences of radionuclide releases to sewage systems from hospitals in Sweden
The report addresses radioactive discharges to sewers originating from hospitals, mainly in the form of the excretion of patients treated with radioisotopes for diagnostic or therapeutic purposes. Assessments of doses to the public, including sewage workers, arising from such discharges are performed. Doses are compared against the exemption level of 10 μSv/a and the dose constraint of 100...
