Development of a beta-probe based on scintillation fibers and silicon photomultipliers

Beta radiation (electrons and positrons) coming from radiotracers of interest in nuclear medicine have generally a short range of a few mm in tissues. Beta-probes are appropriate for the detection of surface radiation which can be used in clinical and preclinical applications. We have developed a be...

Summary:Beta radiation (electrons and positrons) coming from radiotracers of interest in nuclear medicine have generally a short range of a few mm in tissues. Beta-probes are appropriate for the detection of surface radiation which can be used in clinical and preclinical applications. We have developed a beta-probe based on scintillation fibers and silicon photomultipliers. Scintillation fibers with different size, geometry and cladding configuration were compared in terms of beta particle detection efficiency and light collection. Silicon photomultipliers of different sizes and sensitivities were tested with an in-house developed readout electronics.
