AUTOMATION OF THE ACQUISITION AND PROCESSING OF DATA FROM THERMOLUMINESCENCE DOSIMETER READERS

Abstract

The thermolumlnescence dosimeter (TLD) readers used In the Laboratory of External Dosimetry of the Center of Protection and Hygiene from the Radiations are old-fashioned. The data obtained by this equipment must be manually written down In arder to subsequently, process them and these data do not remain registered In any memory for future analysis. This paper describes the desing and creation of a system that conneds these TLD readers to a personal computer. The system Includes a data acquisition card with several analogue input channels, counters, timers as well as digital inputs/outputs and software, In arder to control the acquisition and processing of the data.
