• 2020:08 Identifying radiologically important ESS-specific radionuclides and relevant detection methods

  construction in Lund, Sweden. High-energy protons will be accelerated in a linear accelerator and generate neutrons when hitting a rotating target of tungsten. This spallation process will also generate a wide ... wide range of different radioactive by-products of which a small part will be released to the environment during normal operation. Furthermore, in case of an accident scenario, gases and aerosols might be...

• 2010:44 Recent Research on EMF and Health Risk Seventh annual report from SSM:s Independent Expert Group on Electromagnetic Fields, 2010

  This year has seen the publication of the long awaited Interphone study looking at brain tumour risk in mobile phone users. However, the advent of these new data does not change the overall picture being ... being that for up to about ten years of mobile phone use associations with brain tumour risk are unlikely. This conclusion is based on the collective of studies on mobile phone use and brain tumour risk as...

• 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

  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 from the radiation target will be...

• 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 ... 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 each other...

  includes a preamble in which the work process of the group is described. In particular the methods for evaluation of the results of studies as well as for synthesizing the scientific evidence within a research ... described. A recent childhood leukaemia study from Japan is in line with previous epidemiologic findings. The effects of RF fields on many different genotoxicity endpoints have been evaluated both in vitro...

• 1999:13 Determination of the Neutron and Photon Dose Equivalent at Work Places in Nuclear Facilities of Sweden

  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 ... fluences evaluated from measurements with multisphere systems were recommended to be used for the calculation of dosimetric reference values for comparison with the readings of the dosemeters applied simultaneously...

• 2022:13 Long-time variations of radionuclides and metals in the marine environment of the Swedish west-coast studied using brown algae

  The marine environment receives discharges from nuclear facilities around the world as well as in Sweden. The brown seaweeds, Fucus serratus and Fucus vesiculosus, are important organisms in the marine ... usefulness in environmental monitoring as a bio indicator. Bio indicators provide information on levels and variations of elements, like for example radionuclides, in the marine environment. By studying...

• 2011:30 A fatigue analysis including environmental effects for a pipe system in a Swedish BWR

  The effect of the environment on fatigue design has been the subject of intense study in USA, Japan and elsewhere. Several reports indicate a potentially large influence of the environment, leading to ... the proposal of entirely new analysis procedures. SSM has in an earlier project sponsored research to evaluate the technical basis for these proposals, see SSM Research Report 2011:04. In the current report...

• 2023:03 A novel method for retrospective analysis regarding appropriateness of radiological examinations

  The use of X-ray diagnostic examinations, especially computed tomography, has increased in recent decades and it is essential that this increase is justified and contribute to a better care of the patients ... ionising radiation. In the radiation protection system, this is expressed as the justification principle and is of particular importance for medical exposures because dose limits for this type of exposure are...
