Mobil Alfaspektrometri (Mobile Alpha-Ray Spectrometry).

摘要

The aim of this work was to investigate the possibilities of alpha-ray spectrometry in situ. This started from a theoretical study about the circumstances that measurements of alpha emitters rely on. Then, a prototype was built on a basis of a silicone surface barrier detector and portable electronic equipment. This equipment was used for experiments on five different samples with different nuclide mixtures. Each sample was measured during two different conditions, in vacuum and in normal air pressure. The report describes the prototype and the results of the experiments made.
