1. 1. High spatial resolution study of local corrosion effects on BWR-fuel cladding : Using a combined method of GEANT4 and lwrChem

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Martin Nilsson Lind; [2023]
   Keywords : fission; zircaloy; corrosion; radiolysis; radiation; BWR; Monte Carlo; GEANT4; lwrChem;

   Abstract : The core of a BWR constitutes a highly complex radiational and chemical environment. Nuclear fission is utilized to generate power and as a consequence, large quantities of ionizing radiation are produced. Gamma and beta-particles along with neutrons have the sufficient ranges to escape the fuel rods and deposit energy in the reactor coolant. READ MORE

3. 2. Exposure Monitoring and Dosimetry - Optimizing Radiation Protection in Interventional Cardiology

   University essay from Umeå universitet/Institutionen för fysik; Umeå universitet/Institutionen för strålningsvetenskaper

   Author : Amanda Pettersson; [2023]
   Keywords : Interventional cardiology; Radiation protection; Air kerma measurements; Radiation shielding; Projection angle;

   Abstract : During interventional cardiology (IC), medical staff are exposed to scattered ionizing radiation from the patient, potentially leading to various radiation-induced health effects. Therefore, shielding devices are routinely used to reduce occupational exposure during IC procedures. READ MORE

4. 3. 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.

5. 4. osimetric impact of system spe cific geometric distortion on head and neck treatment plans in MRI only based radiation therapy

   University essay from

   Author : Jesper Brovall; [2022-01-13]
   Keywords : Medical physics; Dosimetry; MRI; Radiation therapy;

   Abstract : Background/ purpose: Because of the superior soft tissue contrast, in comparison with computed tomography (CT) data, magnetic resonance imaging (MRI) is of high interest to include in a larger extent in the ra diation therapy (RT) process. In an MRI only workflow, the CT scan is excluded and a synthetic CT is used for treatment plan ning. READ MORE

6. 5. FETAL DOSE ESTIMATION IN ABDOMINAL AND PELVIC CT EXAMINATIONS

   University essay from

   Author : Olivia Carlstein; [2021-05-10]
   Keywords : Medical physics; Fetal dose; abdominal CT examination; pelvic CT examination; phantom measurement;

   Abstract : Purpose: The purpose of this is study was to compare different methods for estimating the fetal dose, how much the different methods differ from each other and on which dose levels the fetal doses are estimated to. Theory: A radiological procedure should always be justified and in the case of a pregnant patient the justification should include both the mother and the fetus. READ MORE
