CROME (Cern RadiatiOn Monitoring Electronics) is the new read-out electronics for radiation protection at CERN. It performs analog-to-digital conversion of the current signal generated by the radiation detectors (ionization chambers) installed in and outside CERN perimeter providing a continuous real-time measurement of ambient dose equivalent rates. It generates radiation alarms, interlock signals and provides long term permanent and reliable data logging. More info at the Wiki page
