ELECTRICAL CHARGE IN RADON DAUGHTER DEPOSITION - A CRITICAL-REVIEW

The roles that electric charges play in the various deposition processes of radon daughter atoms has been a matter of conjecture for many years. In this review, several possible effects of charge are described. The sources of cluster ions in indoor air and their attachment to aerosol particles are then considered. Since the 'background' aerosol is central to the questions of deposition, its physical behaviour is discussed in the context of charge attachment and other properties. Data from experiments on decay product neutralisation during the first few seconds after birth, room air interactions from several different types of experiments, and deposition following inhalation are then reviewed. The interpretation of these experiments is given and directions for research needed better to identify critical issues are isolated.
