  1. 11. Designing a fast and robust device for measuring and providing graphical visualization of the number of 60Co sources in a Leksell Gamma Knife®

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Simon Andersson; [2020]
    Keywords : Cobalt 60; LGK; Leksell Gamma Knife; Counting sources; Elekta Instrument AB;

    Abstract : The Leksell Gamma Knife® (LGK) is a device for performing radiosurgery. The LGK contains approximately 200 radioactive sources whose beams intersect in a focal point in order to treat brain tumours. Quality assurance tools are used at Elekta to indirectly assess the number of sources in an LGK from the total amount of radiation. READ MORE

  3. 12. Evaluation of Epistemic Uncertainties in Probabilistic Risk Assessments : Philosophical Review of Epistemic Uncertainties in Probabilistic Risk Assessment Models Applied to Nuclear Power Plants - Fukushima Daiichi Accident as a Case Study

    University essay from KTH/Filosofi

    Author : Omed A. Rawandi; [2020]
    Keywords : Probabilistic Risk Assessment; PRA; Probabilistic Safety Assessment; PSA; Uncertainty; Epistemic Uncertainty;

    Abstract : Safety and risk assessment are key priorities for nuclear power plants. Probabilistic risk assessment (PRA) is a method for quantitative evaluation of accident risk, in particular severe nuclear core damage and the associated release of radioactive materials into the environment.

  4. 13. Temporal and genetical constraints of the Cu-Co Vena-Dampetorp deposit, Bergslagen, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Dino Leopardi; [2020]
    Keywords : Bergslagen; Vena; Dampetorp; Cu-Co; sulphide melting; Bastnäs-type; cobaltite; arsenopyrite; titanite dating; sulphide mineralization; sulphide re-mobilisation.; Earth and Environmental Sciences;

    Abstract : The Bergslagen Province is known for containing major Zn-Pb-Ag and Zn-Pb-Cu-Ag sulphide mineralizations with associated iron-oxide skarns and a lot of research have focused on understanding them. However, Cu-Co deposits like the Vena-Dampetorp deposit have received less attention. READ MORE

  5. 14. Optimization of Acquisition Time for 177- Lu SPECT with Two Energy Windows

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Fanny Mörnsjö Centofanti; [2019]
    Keywords : Medicine and Health Sciences;

    Abstract : Background & Aim: The imaging process following the treatment of 177Lu-DOTATATE is in some medical clinics demanding on both patients and the clinic. Usually a number of images are acquired, with different time intervals to the time of injection. READ MORE

  6. 15. Implementation and characterization of Silicon detectors for studies on neutron-induced nuclear reactions

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Leo Lehtilä; [2019]
    Keywords : Silicon detector; Silicon telescope; Ultra-thin silicon detector; Energy resolution; Radioactive source; Am-241; Cf-252; Fission Fragments; Alpha Particles;

    Abstract : Energy resolution characteristics of silicon surface barrier detector signals amplified by different preamplifiers and spectroscopic amplifiers have been studied. The characterization has been done using alpha particles from an 241Am source and spontaneous fission fragments from two Cf sources. READ MORE
