Fields of view for airborne gamma-ray detectors
Selected references for gamma-ray spectrometry
One of the characteristics of gamma radiation is that it is quite penetrating—gamma-rays from the radioactive decay of K, U and Th in the ground can penetrate through hundreds of metres of air before being completely absorbed in the atmosphere. This raises the question of what the “footprint” of an airborne gamma-ray measurement is. Or, put another way, what is the “field of view” of an airborne detector at a given height. To get an insight into this, we can calculate what percentage of the detected gamma radiation originates from within a circle of specified diameter beneath the detector.
