At our station we allow individuals to decay if we believe it is radon but our levels are not high enough to get > 100 ncpm just to alarm the IPM monitors. Most times within 10-15 minutes folks have decayed enough to pass the monitors. We have also used isotopic analysis to validate or whole body counts, but always require decay and monitor release

We often struggle with many monitor alarms due to radon which makes it harder to drill down on legitimate contamination events. Have any utilities had success reducing these events? How did you achieve this? Have there been any noticeable changes in these events with different types of worker coveralls?
