• 2016:15 Recent Research on EMF and Health Risk, Eleventh report from SSM’s Scientific Council on Electromagnetic Fields, 2016

  Including Thirteen years of electromagnetic field research monitored by SSM’s Scientific Council on EMF and health: How has the evidence changed over time? The report has the objective of covering the previous ... previous year’s research in the area of electromagnetic fields (EMF). The report gives the Swedish Radiation Safety Authority an overview and provides an important basis for risk assessment. The present annual...

• 1994:14 Evaluation of acceptance criteriafor data on environmentally assistedcracking in light water reactors

  The assessment of possible sub-critical crack growth through environmentally assisted cracking (EAC) is a commonly encountered problem in safety evaluations of light water reactor components. The numerous ... medium and loading), but their interactions are highly complex. Field assessments usually rely on the evaluation of experimental results, with or without parallel attempts to model the cracking process, but...

• 2017:13 Monte Carlo patient-specific pre-treatment QA system for volumetric modulated arc therapy

  Background The clinical use of volumetric modulated arc therapy (VMAT) has augmented rapidly since it became commercially available. As a result, the need for comprehensive quality assurance (QA) has increased ... increased. Current practices in Sweden normally compare the delivered dose with the planned dose based on measurements with different methods, for instance: portal dosimetry, point dose verification and/or...

• 2022:14 Weld residual stress and strain measurements on a mock-up with single layer strip cladding common in reactor pressure vessels

  SSM perspektiv Bakgrund Reaktortryckkärl tillverkas vanligtvis av låglegerade ferritiska stål som på insidan beläggs med ett eller flera lager av rostfritt stål, ... Resultaten från mätningarna visade på dragspänningar i nivå med sträckgränsen i pläteringen och cirka 30 mm in i grundmaterialet. Efter värmebehandling konstaterades kraftigt reducerade spänningar i grundmaterialet...

• 2017:25 Evaluation of weld fatigue reduction in austenitic stainless steel pipe components

  Background The performed investigation is a continuation of the work performed in SSM 2015:38 where fatigue tests were performed on pressurized welded austenitic stainless steel piping components. The ... to a realistic variable amplitude loading with mainly reversed bending deformation and particular focus on high cycle fatigue. The previous fatigue results were quite dependent on the estimation of the...

• 2007:10 Radiological consequences of radionuclide releases to sewage systems from hospitals in Sweden

  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 ... discharges are performed. Doses are compared against the exemption level of 10 μSv/a and the dose constraint of 100 μSv/a. As a basis for the dose assessments, information on the use of radionuclides in Swedish...
