First experience in automation of TL measurements of personnel doses

The design and performances of the automated TLD system - Model 748 are described, that has been used in the Institute of Nuclear Physics (Krakov, Poland) since Jan. 1, 1976 for personnel dosimetry. The system comprises KD-75 - type dosimetry cards and an apparatus for meassuring radiation doses. In each card there are three LiF detectors capable od measuring β-, γ- and X - radiation doses. the model 748 is designed for the dose range of 1-1000 mrad. Accumulated data are presented on the accuracy, stability and reliability of measurements. The system is capable of processing up to 60 TL cards per hour, the identity of a person under control, the person's professional background, annual doses and doses got in a current year being put into a computer
