The inclusion of training aids in environment monitoring systems

A training program has been developed based upon the Dounreay Environmental Monitoring System (DEMS). The program is written in C on a Harwell Modular computer. The program simulates an accident somewhere within the facility, selected at random and models the spread of contaminants through it in real time. The model considers the dispersion of contaminant in the source room and the distribution of contaminant between rooms. Air contamination levels and radiation doses are calculated at each of the monitoring positions and are displayed on a VDU in the same format as the DEMS display. (author)
