Abstract
IT is well known that the dust particles contained in moist air streaming with considerable velocity through a small hole towards a plane surface are deposited on it. This effect is currently used to determine the content of dust in the air by means of dust-counters. We thought it would be interesting to investigate in the same way the behaviour of atoms of radon and its disintegration products contained in air.
