If the ground dose rate is 55 cGyph and the aerial dose rate is 5 cGyph, what is the air-ground correlation factor?

To find the air-ground correlation factor, you need to compare the ground dose rate to the aerial dose rate. The air-ground correlation factor can be calculated by dividing the ground dose rate by the aerial dose rate. In this case, you would take the ground dose rate of 55 cGyph and divide it by the aerial dose rate of 5 cGyph.

Performing the calculation, you have:

Air-Ground Correlation Factor = Ground Dose Rate / Aerial Dose Rate

Air-Ground Correlation Factor = 55 cGyph / 5 cGyph = 11

This means that for every unit of dose measured in the air, there are 11 units of dose measured on the ground. Therefore, the air-ground correlation factor is accurately determined to be 11, making it the correct answer. Understanding this relationship is crucial in CBRN reconnaissance as it helps operators assess the impact of contamination on the ground relative to what’s detected from the air, allowing for better planning and response strategies.
