Abstract:
Abstract Radon (222Rn) is a widely used tracer in groundwater and surface water studies. In some
applications of radon, samples need to be collected from deep submerged areas or discharge points such as caves
or springs, locations typically accessed by scuba diving. However, there are no established sampling methods
for collecting water by scuba diving for Rn analysis. We assessed four underwater sample collection methods:
(a) injection into a catheter bag followed by transfer to a bottle after the dive, (b) air purging and then filling of a
bottle by allowing gas to escape, (c) air purging followed by gas escape, and then overfilling of water with a
syringe, and (d) collection with a syringe followed by transfer to a bottle. The samples were collected from the
anchialine caves of the Yucatan Peninsula which are the longest underwater cave systems. The samples were
analyzed using the same Rn‐in‐air analyzer and protocols. Statistical comparison of sampling at the same
location with different methods showed no significant differences in Rn activity. No collection method is
superior in terms of measurement quality; operational simplicity is thus preferred. Statistically significant
differences in activity were observed between fresh and saline samples from the same cave, with higher
activities in the fresh samples, regardless of sampling method. The saline groundwater therefore has a lower
residence time, suggesting vigorous landwards flow. Our assessment shows that in situ sampling of discrete
water samples for Rn tracing by divers is a useful and powerful approach allowing the study of otherwise
impossible sites.
