  2. 1. Radiobiological effects of alpha-particles from Astatine-211: From DNA damage to cell death

    Author : Kristina Claesson; Göteborgs universitet; []
    Keywords : ;

    Abstract : ABSTRACT In recent years, the use of high linear energy transfer (LET) radiation for radiotherapeutic applications has gained increased interest. Astatine-211 (211At) is an -particle emitting radionuclide, promising for targeted radioimmunotherapy of isolated tumor cells and microscopic clusters. READ MORE

  4. 2. Advances in time–domain induced polarisation tomography : Data acquisition, processing and modelling

    Keywords : Tomography; Signal–to–noise ratio; Waveform; Duty–Cycle; induced polarisation; Electrical properties;

    Abstract : What would you find below your feet – how do you find out? Perhaps you could look at a geological map, drill, or dig? That could work, but sometimes the maps are not detailed enough, and digging everywhere to find out is impractical. Imagine if you could develop a method that allows you to see straight through the ground, as x–rays through the body! To some extent, such methods already exist; you can for example send electric current into the ground that tells you what lies beneath when it returns. READ MORE

    Abstract : A phosphor or scintillator is a material that will emit visible light when struck by ionising radiation. In the early days of diagnostic radiology, it was discovered that the radiation dose needed to get an image on a film, could be greatly reduced by inserting a fluorescent layer of a phosphor in direct contact with the film.
