Radon-222 and radium-226 occurrence in water: a review
Posted on 2016-11-24 - 12:51
A total of 2143 dissolved radon-222 and radium-226 activity concentrations measured together
in water samples was compiled from the literature. To date, the use of such a large database is the first
attempt to establish a relationship for the 226Ra–222Rn couple. Over the whole
dataset, radon and radium concentrations range over more than nine and six orders of magnitude, respectively.
Geometric means yield 9.82±0.73 Bq l-1 for radon and 54.6±2.7 mBq l-1 for
radium. Only a few waters are in 226Ra–222Rn radioactive equilibrium, with most of
them being far from equilibrium; the geometric mean of the radium concentration in water/radon concentration in
water (CRa/CRn) ratio is estimated to be 0.0056±0.0004. Significant differences in
radon and radium concentrations are observed between groundwaters and surface waters, on the one hand, and
between hot springs and cold springs, on the other. Within water types, typical ranges of radon and radium
concentrations can be associated with subgroups of waters. While the radium concentration characterizes the
geochemistry of the groundwater–rock interaction, the radon concentration, in most cases, is a signal of
non-mobile radium embedded in the encasing rocks. Thus, the 226Ra–222Rn couple can
be a useful tool for the characterization of water and for the identification of water source rocks, shedding
light on the various water–rock interaction processes taking place in the environment.
