A time-dependent map of radon-222 flux density at the Australian land surface (July 1979-June 2010)

Brief description

Radon-222, or radon is a radioactive noble gas which is exhaled by soil and rock to the atmosphere. Although commonly assumed to be constant, the land-surface flux of radon varies in space and time. This is a time-dependent map of radon-222 flux density at the Australian land surface with a spatial resolution of 0.05 degrees and temporal resolution of one month. This is a research-quality data set which is derived from a variety of measurements and model output, as there are too few radon flux measurements to generate a map directly from these. As a result, uncertainties are larger and poorly characterised when compared with maps of other quantities which can be obtained directly from measurements. Potential users are encouraged to contact the primary investigator both for guidance in applying this data set and to stay informed about upcoming revisions. The authors can also provide data for different time periods and in different formats.
