2018:13 Prestudy - Detectors for variance measurements
radiation on which models for cellular and sub-cellular damage can be built. Experimental data is fundamental in this context for quality assurance and bench-marking of models and simulations. Direct measurements ... measurements are also of practical importance for radiation quality determinations in radiation therapy and radiation protection. In the experimental microdosimetric variance-covariance method, the radiation quality...

2018:08 Calculated radiological consequences of applying European clearance levels to scrap metal from the decommissioning of Swedish nuclear facilities
Clearance of materials means a decision that such materials can be released from regulatory control and used or disposed of without restrictions from a radiation protection point of view. According to regulations ... regulations issued by the SSM, such decisions must be based on thorough measurements of the activity content and it must be shown that the activity content is below certain values, so called clearance levels. Clearance...

2018:01 Monte Carlo patient-specific pre-treatment QA system for volumetric modulated arc therapy
which means that the entrance of each patient field is measured with a diode in a specific point and compared to the calculated dose in the same point. Volumetric Modulated Arc Therapy (VMAT) is an advanced ... a linear accelerator with a continuous rotating gantry combined with dynamic collimator movements and varying dose rates. Due to the complexity of VMAT, the previous in vivo dosimetry procedure is not...
