Exploring atmospheric radon with airborne gamma-ray spectroscopy [PDF]

, 2017
$^{222}$Rn is a noble radioactive gas produced along the $^{238}$U decay chain, which is present in the majority of soils and rocks. As $^{222}$Rn is the most relevant source of natural background radiation, understanding its distribution in the ...
