Frequent Questions

How does gamma gross count rate relate to exposure rate?

There is no direct relation between gamma gross count rate and exposure rate.  These two measurements are made by separate detectors with different purposes and configurations. The exposure rate data indicate the amount of radiation in the vicinity of the monitor over a period of time (typically hours). In comparison, gamma gross count rates are measurements made by a detector that analyzes radiation emitted from particulate collected on air filter.
