“…In the last years, research groups have dedicated efforts to the development and use of coupling OF (optical fibers) to spectroscopic instrumentation for several types of applications [1]. In this work, the purpose is to use an OF cable in a radiation detection system to allow more flexibility in in situ analyzes using the EDXRF (energy dispersive X ray fluorescence) technique.…”

Abstract:In the last years, the production of optical fibers cables has made possible the development of a range of spectroscopic probes for in situ analysis performing beyond nondestructive tests, environmental monitoring, security investigation, application in radiotherapy for dose monitoring, verification and validation. In this work, a system using an optical fiber cable to electromagnetic signal transmission from a NaI(Tl) radiation detector is presented. The innovative device takes advantage mainly of the optical fibers large passband, small signal attenuation and immunity to electromagnetic interference to application for radiation detection systems. The main aim was to simplify the detection system making it to reach areas where the conventional device cannot access due to its lack of mobility and external dimensions. Some tests with this innovative system are presented and the results stimulate the continuity of the researches.
