The displayed reports are shortened to 15 CAMs each to save on space. In each report, the CAM identified as RI0583L is the CAM displayed in the above figures. Even in the sample shown in Figure 2 is not easy to be sure that the change is significant without verifying by calculation. The third set of data shows very little change over the night. On this night, most CAMs cannot be said to have responded to radon.
Asterisks indicate unavailability of the system.
Conclusion PIMS data has been shown to be a valuable resource in evaluating CAM performance. A statistical analysis of the nightly readings has shown that, during any given week, there will probably be at least one occurrence of significant radon readings.
