The inhalation of short-lived decay products of [220,222Rn]Radon accounts on the average for half of the effective dose equivalent from all natural sources of radiation. Sources of emanation/exhalation and subsequent mechanisms of indoor invasion of [220,222Rn]Radon are discussed. Both seasonality of [220,222Rn]Radon concentration (in- & outdoor) and the indoor ventilation rate are considered.
