Full Event Report for the 17th November

In the last 24 hours, local background levels have risen to 49% above the 4 year average of 0.10 uSv/hr. It is suggested that during these elevated background radiation events, if it rains,  you keep children and pets out of the rain, plus re-divert rain tank inflows.

 

See November day chart.

To keep up to date on local background radiation levels, regularly look at day chart, at the monitoring site.

Testing is showing a significant amount of Radon washout during the rain events that coincide with elevated background.

 

Report from the Nimbin monitoring station in the last 24 hours.

"Took a swab from the windscreen half an hour ago after many showers, and measured more than 650cpm(SBT10) throughout the first 10 mins."

 

See  rain swab test chart showing significant Radon decay daughter isotopes captured from the edge of a storm, here at Caloundra on the evening of the 17th.

This swab will be further tested to see if any long life isotopes are present.
