The automated Riso TL/OSL reader system is used worldwide for luminescence dating, retrospective dosimetry environmental dosimetry and material characterization. In response to requests from many users we have re-designed the reader by incorporating a variety of new hardware and software features. New hardware features include a two-speed sample turntable, a new detachable beta irradiator with a Be window vacuum interface and the incorporation of an on-board minicomputer.,A completely new software concept was developed that allows the user unlimited control of the reader and has, at the same time, made the new generation Riso TL/OSL readers extremely flexible and user friendly. A description of the new system is given and measurement results are presented to demonstrate its capabilities. (C) 1997 Elsevier Science Ltd.
