The system is equipped with a touch-screen operator panel, where the ELSE NUCLEAR software is installed. The software displays in real time the measurement, controls the system status, and allows to set the operative parameters (including the alarm thresholds), to manage the measurement steps. The system displays the specific and the total activity, or the count rate and integrated counts. The software is equipped with a calibration routine, to be used with a Marinelli calibration source (available as accessory). The system provides also a test program, separate from the main application, to be used for maintenance or periodical quality controls. (*): only if the pump is included, i.e. when it is not available in the sampling/hydraulic equipment which LEM shall be connected to.LEM system is composed of the following main parts:
The system provides also I/O contacts through dedicated connectors:
LEM
LIQUID EFFLUENT MONITORING SYSTEM
The LEM system allows to sample the liquid effluents and to perform a gross gamma measurement of the specific activity in Marinelli geometry.
