  1. 6. Light scattering and absorption in tissue - models and measurements

    Författare :Annika M K Enejder; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tissue optical properties; Light absorption; Fluorescence spectroscopy; Atomic and molecular physics; NIR spectroscopy; Fysicumarkivet A:1997:Enejder; Light scattering; Atom- och molekylärfysik;

    Sammanfattning : In this work a number of theoretical models, describing light propagation in matter, have been applied to and developed for the examination of tissue. The aim was to model the light scattering and absorption in tissue in order to improve the understanding of underlying mechanisms of laser-based diagnostics and treatment modalities utilised for cancer and cardiovascular diseases.

  3. 7. Radiation exposure of human populations in villages in Russia and Belarus affected by fallout from the Chernobyl reactor

    Författare :Christian Bernhardsson; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chernobyl; caesium; effective dose; OSL; NaCl; TL; LiF; radiation protection survey instruments; deposition variability; long-term series;

    Sammanfattning : A quarter of a century has elapsed since the catastrophe at the nuclear power plant in Chernobyl. The radioactive fallout affected all the European countries and most severely the three countries of Belarus, Russia and Ukraine. LÄS MER

  4. 8. Noise exposure, hearing protection and hearing loss. A long-term study at an automobile sheet-metal pressing plant

    Författare :Pawel Brühl; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; audiology; Otorhinolaryngology; noise zone; dosimetry; human; industry; Hearing conservation programme; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

    Sammanfattning : The design and implementation of a hearing conservation programme in a heavy industry with high noise levels is described. Action was taken on several points, including noise measurements, noise reduction, education on hearing protector use, and audiometric monitoring. LÄS MER

  5. 9. Household salt as an emergency radiation dosemeter for retrospective dose assessments using optically stimulated luminescence

    Författare :Maria Christiansson; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Optically stimulated luminescence OSL ; household salt; NaCl; retrospective dosimetry; accident dosimetry;

    Sammanfattning : In the event of a radiation accident, it is crucial to make rapid estimates of the absorbed dose received by both emergency workers, so-called first responders, and members of the public. Today, only personnel in rescue teams responding to nuclear emergencies have access to individual dosemeters. LÄS MER

  7. 10. Superparamagnetic iron oxide nanoparticles (SPIONs) as a multimodality imaging probe for sentinel nodes : Design and Preclinical Evaluation

    Författare :Renata Madru; Lund Medicinsk strålningsfysik; []
    Nyckelord :iron oxide; nanoparticles; SPIONs; PET-MRI; SPECT-MRI; SPECT-MRI- optical imaging; sentinel lymph node; SNL;

    Sammanfattning : Breast cancer and malignant melanoma disseminate through the lymphatic system and the first metastases arise in one or two regional, sentinel lymph nodes (SLNs) draining the primary tumour site. Therefore, identification and characterization of the SLNs is of major importance for cancer staging and for choice of therapy in patients. LÄS MER
