Foreword
A volume covering many roles of radon in the environment is a welcome addition to the geochemical literature. Radon is the maverick element of the noble gas clan. While there are shared familial characteristics, radon is governed by its own rules. It retains no memory of its history beyond a few times the meager half-lives of its natural isotopes, of a few days for 222Rn and under a minute for the more fleeting 219 Rn and 220Rn. These have concentrations that are typically maintained by their parent Ra isotopes, whose concentrations are in turn subservient to those of their U and Th progenitors. Radon will sometimes set off from the support of parental secular equilibrium, but this unsupported break is always short-lived. A radon atom can be set free from a solid when brought into existence during the decay that produces it along with a 4He atom sibling, though these recoil from one another at birth, a violent process that projects them in opposite directions, sometimes right out of the solid. It is the subsequent travel that provides the opportunities for using Rn isotopes as a
