  1. 1. Internal Dosimetry in Nuclear Fuel Fabrication : Occupational Exposure to Uranium Aerosols

    Författare :Edvin Hansson; Mats Eriksson; Håkan Pettersson; Per Roos; Michael Sandborg; Bastian Breustedt; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Uranium; Aerosol; Internal; Dose; Nuclear;

    Sammanfattning : The production of nuclear fuel can be associated with occupational exposure to ionizing radiation from radioactive decay of uranium. Such exposure must be sufficiently low and radiation doses adequately determined. Radiation doses from internal exposure, i.e. LÄS MER

  3. 2. Internal dosimetry. Macroscopic, small-scale and microscopic perspectives

    Författare :Cecilia Hindorf; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiobiologi; Nukleärmedicin; radiobiology; Nuclear medicine; B-cell lymphoma; Radioimmunotherapy; Radionuclide therapy; Internal dosimetry; Radiopharmaceutical technology; Radiofarmaceutisk teknik;

    Sammanfattning : Internal dosimetry deals with the assessment of absorbed dose for radionuclides distributed inside the body. The absorbed dose is in its turn used for correlation with the biological effect caused by the irradiation. LÄS MER

  4. 3. Internal Dosimetry Development and Evaluation of Methods and Models

    Författare :Lena M Jönsson; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; crypt cells; intestine; radionuclide; scintillation camera; sestamibi; activity quantification; conjugate view method; Monte Carlo simulation; internal dosimetry; Nuclear medicine; radiobiology; Nukleärmedicin; radiobiologi; medicinsk instrumentering; radiologi;

    Sammanfattning : Radionuclide therapy requires patient-specific planning of the absorbed dose to target volumes, in most cases tumours, in order to achieve an expected biological effect, taking into account that the absorbed doses to normal organs and tissues should be kept as low as reasonably achievable. Therefore, the calculation of absorbed doses has to be as accurate as possible. LÄS MER

  5. 4. Quantification Methods for Clinical Studies in Nuclear Medicine - Applications in AMS, PET/CT and SPECT/CT

    Författare :Marie Sydoff; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear Medicine; AMS; PET CT; SPECT CT; dosimetry; internal dosimetry; quantification; activity quantification; volume delineation; radiation; biokinetics; pharmacokinetics; biodistribution;

    Sammanfattning : An essential part of the development of new radiopharmaceuticals for use in diagnostic nuclear medicine is the determination of its biokinetic properties. The uptake and turn-over of the radiopharmaceutical in the source organs is of great interest since this could determine whether the radiopharmaceutical would be suitable for clinical use or not.

  7. 5. Realistic tissue dosimetry models using Monte Carlo simulations. Applications for radionuclide therapies

    Författare :Erik Larsson; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; internal dosimetry; radionuclide therapy; Monte Carlo; small scale dosimetry;

    Sammanfattning : Radionuclide therapy (RNT) is a generic term for treatment modalities that use a radionuclide labeled to a target-specific molecule. This so-called radiopharmaceutical accumulates in the target, where the ionizing radiation damages the cells. At sufficient levels of radiation, the cells cannot repair themselves. LÄS MER
