Abstract:
Measurements of radon-222 (222Rn) concentration were collected using a 1500 L dual-flow loop radon detector, designed and built by the Australian Nuclear Science and Technology Organisation (ANSTO; Lucas Heights, NSW, Australia) (Chambers et al., 2011; Whittlestone and Zahorowski, 1998). Sampling occurred at 65-75 L min^-1. Calibration occurred during the campaign from a Pylon (Ottawa, ON, Canada) source. Measurements were taken at Cataract Scout Park, Appin, N.S.W. (34°14'42.29"S 150°49'24.97"E) from an inlet 3.94 m above ground level as part of the Characterizing Organics and Aerosol Loading over Australia (COALA-2020) campaign. The campaign ran from mid-January to mid-March, 2020. Reported measurements are at 30-minute time resolution. Concentrations have not been corrected for the response time of the detector but can be on the request of users. See Griffiths et al. (2016) for details.
