Control radon activity results from laboratory experiments to optimize the sparging chamber configuration for Radon-222 analysis
Abstract:
These data were collected in order to optimize a new method for degassing dissolved radon-222 from water. The general premise is the use of a sparging chamber (‘Bell’) that is deployed underwater and uses bubbles to degas the radon. This dataset includes the control (Exchanger) results. See also the control dataset (https://www.bco-dmo.org/dataset/827014). See methodology outlined in Peterson et al., 2013 (Journal of Radioanalytical and Nuclear Chemistry). The sparging chamber is connected to a commercially-available radon-in-air monitor (RAD7; Durridge Co.) via a closed air loop. Air exiting the RAD7 circulates to the bottom of the sparging chamber where it enters via aquarium bubblers. The bubbles rise through the sparging chamber and accumulate in a headspace, from which air is pumped through desiccant back to the RAD7.
Our control to which we compare the sparging chamber is the commercially-available RAD-Aqua (Durridge Co.) which sprays a water sample into a chamber rather than using bubbles. Otherwise, the setups are similar.
Data contained herein are various laboratory testing configurations to optimize dimensions of the sparging chamber, number and type of bubblers, and any benefits from adding an additional sprayer capability to the top of the sparging chamber. All configurations tested are accompanied by a number of replicates.
