About the report

This report describes the results of continuous measurements of airborne radon concentration at the rehabilitated Nabarlek uranium mine in the Alligator Rivers Region, obtained over a period of three years. It is part of a project (the Radon-network) being undertaken by researchers of eriss’ Environmental Radioactivity Section over the last few years (Martin et al in press). It also forms part of the Environmental Radioactivity’s program to assess the radiological status of the Nabarlek uranium mine (see for example Martin et al 2002; Bollhöfer et al 2003; Hancock et al submitted; Martin et al in prep). The equipment for the radon measurements, its setup, calibration and operation are described in detail in reports by Whittlestone et al. (1994) and Tims (2001).
