  1. 1. 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

  3. 2. 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.

  4. 3. Development and Evaluation of an Enzyme-Based Sunscreen

    University essay from Lunds universitet/Bioteknik; Lunds universitet/Bioteknik (master)

    Author : Karolina Eriksson Torfgård; [2023]
    Keywords : Enzyme activity; UV-filter; Protease; Biotechnology; Technology and Engineering;

    Abstract : Ultraviolet radiation (UVR), specifically of UVA and UVB, has been associated with the development of both photoaging and photo-carcinogenesis, potentially leading to cancer. The use of sun protection in the form of UV filters is known to minimize these damages. READ MORE

  5. 4. Evaluation of the DXA radiation environment at Sahlgrenska University Hospital

    University essay from

    Author : Saga Söderholm; [2022-05-18]
    Keywords : Medical physics; DXA; DEXA; Dual-energy X-ray absorptiometry; Bone mineral density;

    Abstract : Purpose: The aims of this work were to evaluate the radiation environment in the dual-energy X-ray absorptiometry (DXA) rooms at Sahlgrenska University Hospital, estimate personnel doses, determine legal requirements for DXA personnel, examine the operators’ view on radiation safety and develop material with dose information for patients and operators. Theory: DXA is a low dose X-ray modality mainly used in osteoporosis examinations, for which it is considered the reference technique. READ MORE

  6. 5. Radiation Shielding Simulations for Small Satellites on Geostationary Transfer Orbit

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Anton Fetzer; [2022]
    Keywords : GTO; Foresail-2; CubeSat; Radiation Shielding; Geant4; Radiation Belts; GTO; Foresail-2; CubeSat; säteilysuojaus; Geant4; säteilyvyöhyke;

    Abstract : The emergence of small and affordable satellites has led to rapid growth in the number of launched satellites over the past two decades. To save costs, small satellites often use mass-produced electronic components not explicitly designed for the radiation environment of space, which reduces reliability and makes them unsuitable for higher orbits.
