1. 1. Can blue mussel shells be used for retrospective 14C-analysis in the marine environment of nuclear power plants?

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Author : Sofia Bjarheim; [2024]
   Keywords : Radionuclide; Marine Environment; Blue Mussels; 14C; Nuclear Power Plant; Physics and Astronomy;

   Abstract : Carbon-14 (14C) is one of the most important contributors to the collective effective dose of the public due to radioactive releases from nuclear power plants. However, the discharge of 14C from nuclear power plants (NPPs) into water has not been measured previously. READ MORE

3. 2. Radiation Effects on GaN-based HEMTs for RF and Power Electronic Applications

   University essay from KTH/Tillämpad fysik

   Author : Wilhelm Holmberg; [2023]
   Keywords : High Electron Mobility Transistor; HEMT; Gallium Nitride; GaN; Silicon Carbide; SiC; Proton Radiation; Galliumnitrid; GaN; Kiselkarbid; SiC; Kisel; Si; HEMT; Transistor; Protonstrålning;

   Abstract : GaN-HEMTs (Gallium Nitride-based High Electron Mobility Transistors) have, thanks to the large band gap of GaN, electrical properties that are suitable for applications of high electrical voltages, high currents, and fast switching. The large band gap also gives GaN-HEMTs a high resistance to radiation. READ MORE

4. 3. Polymer gel dosimetry with MRI-readout for 3D dose verification - detector characteristics and clinical applications

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Thi Guldhill; [2023]
   Keywords : Medicine and Health Sciences;

   Abstract : Background & Purpose: Radiation therapy is an essential treatment for cancer patients with the ultimate goal to deliver radiation doses to the tumour with precision while minimizing exposure to surrounding healthy tissues. Treatment verification is crucial to ensure the accuracy of radiation delivery, for instance by measuring the radiation dose distribution. READ MORE

5. 4. Correlation between Surface and Tumour Motion in Lung Cancer - including Deep Learning Perspectives

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Caisa Kjellström; [2023]
   Keywords : Medicine and Health Sciences;

   Abstract : Purpose: The purpose of this master thesis was to retrospectively investigate correlation between surface and tumour motion in lung cancer patients, alongside deep learning applications of the results. Additional correlations such as age, tumour volume and anatomical placement of the tumour were also investigated. READ MORE

6. 5. A VVER1000 primary side model in Apros

   University essay from KTH/Fysik

   Author : Karl-Edvin Strand; [2023]
   Keywords : Apros; VVER1000; PWR; Modelling; HPIS; Boron acid; Apros; VVER1000; PWR; Modellering; HPIS; Borsyra;

   Abstract : Nuclear power plants generate electricity by means of splitting atoms. The basic safety requirements and objectives are to protect the people, society, and the environment from radiological accidents, limit harmful effects of ionizing radiation during operation and take all reasonable practical steps to prevent radiological accidents.
