  1. 1. Modelling Energy Dependence of Liquid Ionisation Chambers Using Fluence Pencil Kernels

    University essay from Radiofysik

    Author : Josef Lundman; [2012]
    Keywords : LIC; liquid ionisation chamber; response model;

    Abstract : The high demand on accuracy in radiotherapy is to a large extent ensured through measurements of dose to water. The liquid ionisation chamber (LIC) is a type of detector that has several desirable properties for such measurements, e.g. a small active volume and minimal directional dependent response.

  3. 2. The Late Glacial History of the Magellan Strait in southern Patagonia, Chile : Testing the Applicability of KF-IRSL Dating

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Robin Blomdin; [2012]
    Keywords : ;

    Abstract : The timing of the ice margin retreat of the Late Glacial Patagonian ice sheet (PIS) in southern Patagonia has been the object of discussion for many years. In order to resolve questions about the complex response of the PIS to past climate change; geological interpretation and modelling data needs evaluation against absolute chronology. READ MORE

  4. 3. Diode Response Correction in Large Photon Fields

    University essay from Medicinsk strålningsfysik (tills m KI)

    Author : Robert Vorbau; [2010]
    Keywords : silicon diode; energy dependence; diode response; dosimetry; relative dosimetry; dosimeter; radiotherapy; radiation detector;

    Abstract : The energy dependent response of silicon diodes in photon beams is a known problem. A new approach to solve this problem is by correcting the response, a response model was suggested by Yin et al. (2002, 2004), and later refined by Eklund and Ahnesjö (2009). READ MORE

  5. 4. Silicon Diode Dose Response Correction in Small Photon Fields

    University essay from Medicinsk strålningsfysik (tills m KI)

    Author : Artur Omar; [2010]
    Keywords : Radiotherapy; Silicon diode; Dosimetry; Dose response correction; Small field; Strålterapi; Kiseldiod; Dosimetri; Dos-respons korrektion; Små fält;

    Abstract : Silicon diodes compared to other types of dosimeters have several attractive properties, such as an excellent spatial resolution, a high sensitivity, and clinically practical to use. These properties make silicon diodes a preferred dosimeter for relative dosimetry for several types of measurements in small field dosimetry, e.g. READ MORE

  6. 5. Evaluation of materials for ESR-dosimetry: Salts of formic and lactic acid as an example.

    University essay from Medicinsk strålningsfysik (tills m KI)

    Author : Jerker Edén Strindberg; [2008]
    Keywords : ESR-dosimetry; Isotopes; SAR; 2-methylalanine;

    Abstract : The technique of ESR-dosimetry and strategies for investigation of new materials as in regard to their applicability as ESR-dosimeters for radiotherapy has been reviewed. As an example six salts of formic and lactic acid has been evaluated. READ MORE
