Telemetric and data acquisition system for environmental monitoring at the Paks Nuclear Power Station

The detectors of the telemetric system measure the following parameters: the gamma dose rates, the time integral of the 131I activity concentration, the water temperature and the meteorological data needed for dispersion calculations. In the 48 channels of the central acquisition system the data are stored in the form of pulses, with the exception of the wind direction which is characterized by the most frequent direction during the measuring period (one hour or 6 minutes). The results are recorded for further computer analysis. The characteristic features of the system and the possible uses of data obtained, both for normal operation and emergency, are presented.
