Southern Hemisphere June 2016 Local Background Level Report, (7% above average)
Stations Location Map,
What the chart colour codes indicate in the charts.
At this location in the winter months air flows tend to come from the Southern Ocean, rather than from the tropical North. When this happens local background levels tend to drop significantly, so compared to the summer months, winter local background levels approach pre-Fukushima levels. There was a small background level spike on the 19th of June. This occurred as a significant rain event passed over the area.

Southern Hemisphere May 2016 Rain Water Testing Results
This short animation of Northern, and Southern Hemisphere air circulation, shows why we can get detections so far south.

May 2016 down pipe rain water filter test report
There was 123 mm of rainfall in May, at this location.
Small amounts of Pb-210 and Be-7 where detected, plus a very small detection of a possible 77 X-ray from Lead Pb-212, which is the decay daughter of Radon-220. Beryllium Be-7 can be created naturally in trace amounts by spallation in the upper atmosphere by cosmic rays. Lead Pb-210 is the decay daughter of naturally occurring Radon-222 decay. Both Be-7 and Pb-210 can also be released from nuclear power plants, and nuclear accidents. The detection of the Pb-212 77 keV X-ray probably indicates the presents of a small trace of volcanic ash in the air.
