  1. 1. Development of a computational method for determining gamma energy escape from calorimeters at CLAB

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Amela Mehic; [2022]
    Keywords : Nuclear physics; Calorimeter; SNF; MCNP; Dose rate; CLAB; Gamma energy; Fuel assembly; Form function; Attenuation coefficient; Gamma spectroscopy;

    Abstract : Swedish Nuclear Fuel and Waste Management Company- SKB has conducted measurement campaigns at the Swedish central interim storage facility for spent nuclear fuel- CLAB over the years, extending from year 2003 to 2019 where the gamma energy escape was acquired. At CLAB the spent nuclear fuel assembly is inserted into the calorimeter; device intended to measure temperature increase due to decay heat from the fuel assembly. READ MORE

  2. 2. Polymer gel dosimetry - Using MRI-readout, simplified relatively non-toxic mixing procedure tested on FLASH

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Maria Blomstedt; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Background: One of the polymer gel dosimeters available today is the N-isopropylamide (NIPAM) polymer gel dosimeter which has a less toxic monomer compared to other polymer gels and the advantage of being able to be manufactured under normal oxygen levels. Polymer gel dosimeters in general are advantageous independent dosimeters to use for verification of new radiation treatment techniques due to its favorable qualities such as very high resolution, 3D coverage, tissue equivalence and independence of energy and incident direction of the radiation beam.

  3. 3. Environmental radiation measurements at Barsebäck nuclear power plant during the decommissioning phase

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Patrik Dahlström; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Background and aim: The Barsebäck nuclear power plant (NPP) units ceased operations in 1999 and 2005. Now the NPP is in the phase of decommissioning, which is a complicated process that will take many years to complete. Radiological characterization of the surrounding area is a part of the decommissioning process. READ MORE

  4. 4. EVALUATION OF RADIATION DOSES USING CONE BEAM COMPUTED TOMOGRAPHY IN ENDOVASCULAR AORTIC REPAIR AND SCOLIOSIS PROCEDURES

    University essay from

    Author : Louise Strandberg; [2021-04-06]
    Keywords : Medical physics; Cone beam CT; CT; EVAR; scoliosis; radiation dose; effective dose;

    Abstract : Purpose: The study includes the two areas, vascular surgery and orthopedics, and focuses on endovascular aortic aneurysm repair (EVAR) and scoliosis procedures. EVAR procedures contribute to a high radiation dose to the patient and for scoliosis procedures, it is often young girls that are undergoing surgery. READ MORE

  5. 5. Development of methods and software for rapid quality control in fluoroscopy

    University essay from Umeå universitet/Institutionen för fysik

    Author : Majid Khosamadi; [2021]
    Keywords : ;

    Abstract : Background: Fluoroscopy is a common imaging technique which uses X-ray to derive a real time imaging of patient anatomy to determine diagnosis and positioning of patients for interventional procedures. It is therefore important that the fluoroscopy systems maintain their performance. READ MORE
