During an emergency at a nuclear power plant, the on-shift staff could be hard-pressed to sample and analyze the containment atmosphere in a timely manner. Under these conditions, the reading of a high-level radiation monitor in the containment could be the basis for evaluating the radiological severity of the accident. The detection system requirements are relatively straightforward. The system must be able to identify the level of airborne radioiodine in the containment. Because it would be located inside the containment structure, the system must require little or no maintenance for long periods of time. Post-accident conditions could be quite severe; the containment radiation monitor must be able to operate in high exposure levels (up to 10/sup 7/ R/h), high temperatures (up to 200/sup 0/C), and extreme pressure and humidity conditions.
