2016:14 Radiological examinations of children: a study of method options
The Swedish Radiation Safety Authority, SSM, decided in 2011 to investigate the justification of the use of diagnostic computed tomography (CT) for children up to fifteen years of age. The reason is the fact that CT is the main contributor to ionising radiation to the population. During the last decade, the annual number of CT examinations increased by 200%, and during the last 16 years, by...

2015:19 Recent Research on EMF and Health Risk - Tenth report from SSM’s Scientific Council on Electromagnetic Fields, 2015
The objective of the report is to cover the previous year’s research in the area of electromagnetic fields (EMF). The report gives the Authority an overview and provides an important basis for risk assessment. The Swedish Radiation Safety Authority’s (SSM) scientific council monitors the current research situation and provides the Authority with advice on the assessment of risks,...

2014:26 Improved reference and relative dosimetry of small radiation therapy photon beams
Data tables on detector corrections for beam output measurements are provided for a large number of detectors (small air and liquid ionization chambers, silicon diodes, TLD and alanine) manufactured by major vendors, for 6 MV photons from clinical accelerators and for two Leksell Gamma Knife® models. They have been calculated with the PENELOPE Monte Carlo system at an uncertainty of 0.1%.

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...

2013:19 Eighth report from SSM:s Scientific Council on Electromagnetic Fields
The Swedish Radiation Safety Authority`s (SSM) scientific council monitors the current research situation and gives the authority advice on the assessment of risks, authorization and optimization within the area. The council gives guidance when the authority shall give an opinion on policy matters when scientific testing is necessary. The council shall submit a written report on the current...

2012:20 Report from SSM’s scientific council on ionizing radiation within oncology, 2011
Many cancer patients are treated in accordance with written guidelines or clinical trial protocols. The scientific council states that the radiotherapy part in those guidelines and protocols is less well specified than other therapies such as surgery and chemotherapy. This report identifies the key aspects of modern radiotherapy from international radiotherapy organisations and scientific...

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...

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...
