Radon storm

A radon storm is a day-long episode of increased atmospheric radon concentration due to moving air masses.^[1] In Antarctica and over the Southern Ocean, they often occur due to the arrival of continental air from South America^[2] and Africa^[3] and the concept was coined to describe sudden radon concentration increases there.^[4] Naturally, radon increases in concentration threefold in antarctic air in the summer months of December and January.^[4]
