2009:05 Survey on requirements for independent reviews and inspections of electrical and I&C equipment
This survey is a first step to support the work to develop the Swedish regulations in the area of independent review and inspection in the process supporting implementation of electrical equipment in nuclear power plants. The report consists of a summary of different regulations in the area and also an analysis of the differences between the electrical and mechanical field especially in the...

2007:13 Dosimetry audit on the accuracy of Ir-192 brachytherapy source strength determinations in Sweden
The absorbed dose delivered to the patient in brachytherapy is directly proportional to the source strength in terms of the reference air-kerma rate (RAKR). Verification of this quantity by the hospitals is widely recognized as an important part of a quality assurance program. An external audit was performed on behalf of the Secondary Standard Dosimetry Laboratory at the Swedish Radiation...

2010:21 Childhood leukaemia around nuclear facilities
The first indication of a possible relationship between living close to a nuclear installation and the risk of childhood leukaemia came from the United Kingdom in 1983. A cluster of childhood leukaemia in the town of Seascale which is located close to Sellafield was reported in a TV documen-tary. Since then almost 200 studies have been carried out in order to investi-gate the occurrence of...

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 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...

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...

2011:25 Report from SSM’s scientific council on ionizing radiation within oncology, 2010
In this report, three main areas have been highlighted: quality assurance (QA), quality control (QC) and late side-effects including the risk of radiation-induced secondary malignancies. These areas reflect the ongoing activities in leading international radiotherapy organisations. Specific attention is given to new technologies such as image-guided radiotherapy and intensity-modulated...

2021:02 On Water Induced Sensitization of Ni (Fe,Cr) alloys towards Stress Corrosion Cracking in LWR Piping from 1st Principles Modelling
SSM perspective Background In Swedish Light Water Reactors (LWR), stress corrosion cracking of reactor components and welds occurs from time to time. As the nuclear power plants are ageing, it is essential to study and further understand the mechanism for environmentally induced sensitization. Natural cracking is a phenomenon that is difficult to predict and very hard to study since it occurs...

2021:05 Cladding tube rupture under LOCA: Data and models for rupture opening size
SSM perspective Background The Swedish Radiation Safety Authority (SSM) follows the research on fuel performance closely. One aspect that is currently being studied in several research projects is the risk of release of fragmented fuel into the primary coolant in case of an accident. This risk depends on complex conditions were one is the possibility and size of a rupture of the fuel rod...
