This short animation of Northern and Southern Hemisphere air circulation, shows why we can get detections so far south.


Caloundra November 2017 - The elevated background level increases at the end of November 2017 chart have also coincided with a significant increase in Radon detection in the local atmosphere.

The elevated Radon detections over the last couple of months seems to have been a precursor to the outbreak of a very large earthquake swarm in the Pacific off Eastern Australia.

A magnitude 7.0 earthquake at 86km ENE of Tadine, New Caledonia occurred on the 19th November. Zoom in and out on the USGS earthquake map link here to appreciate just how large this swam of earthquakes was, for the month of November.

The recent Radon increases would have been a contributing factor to the November elevated background levels, but not the only factor. (Local live Radon monitoring chart.)
