Radioluminescence : A simple model for fluorescent layers - analysis and applications

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. Thus, introducing the step of converting the ionising radiation to light in a first step. Going forward in time, film has been replaced with photodetectors and there is now a variety of imaging x-ray systems, still based on phosphors and scintillators.PhD Gavin Poludniowski who skilfully brought pieces together and in the process of challenging the LAC-model, made it better than ever. I would also like to thank: My co-authors Medical Physicists Markus Hulthén and Erik Wåhlin who saved me, always in the last minute. My various head(s) at Karolinska University Hospital who finally got me to reach my long-awaited goal of putting my act together in research My co-workers at the department of Medical Physics who patiently listened to whatever academic challenge I was currently wrestling with. Particularly Angeliki, Jörgen and Shahla. I owe you.Last but by no means least; the remains of my family not backing one bit from their support even when theirs and my life was in a turmoil.

Exploring the work and competence of interactive researchers

“…The complex relationship between the researcher and the practitioner has been illustrated as an interaction between two systems (Ellström et al , 1999; Svensson et al , 2015). On the one hand, there is the research system that is driven by researchers’ typical activities, such as formulating research problems, designing empirical studies, collecting and analysing data, and developing conceptual frameworks and theories.…”
