WebiSmarts System

Web-based area and stack monitoring system with DPU-3 monitors

Primary function
Web software that receives online data from DPU-3 area monitors and shows them on colour-coded maps
Functions
One year of history per point; isotope identification of effluent; over 20 maps; real-time background subtraction; dose and dose rate at the same time
System components
Web software, DPU-3 monitors (four detectors each) and a stack monitor; maps, points and history are stored on a server and accessed with a browser
