This spike in radiation was detected on the 8th January 2012, on the Sunshine Coast, Australia. The wind direction was NNE at 22degrees. Geiger Counter Alarm starting going off at around 6.30 pm. Raised radiation levels lasted until around 9.45 pm.
The Gammascout Geiger Counter alert alarm was set to go off at 0.50 uSv/Hr, and to record data every 10 minutes. I was shocked to hear the Geiger alarm going off. Visual observations showed actual peaks reaching 0.80 uSv/Hr. Even though this chart of the downloaded 10 minute interval recorded data is not showing the true peaks that occurred, it is still dramatic.
If the maximum visual observed peak had been recorded, the peak on this chart would be over twice as high!
The beginning of the chart would be considered average background for our area. Background radiation levels here, with 4 years of recorded data to refer to, has averaged around 0.10 uSv/Hr. The background radiation level was peaking 8 times above average during this event!
Either some of the radioactive fall out from Fukushima has briefly reached us, or there is some seismic activity N/NE of our location in the Pacific Ocean which has released a spike in radon gas. Just a theory.
The dramatic drop in background reading just before the spike is also interesting. Anyone have any ideas?
I promised members that I would post any unusual radiation data, I just didn't expect to be doing this so soon.
Here is an article at The Sunshine Coast Daily, the local paper on this event, plus an interview on New Zealand radio station GreenplanetFM. Click the play button next to the speaker icon, to listen to the radio interview, that starts after a bit of an introduction on synchronicity.
I have since had a report from someone in New Zealand. He detected 0.33 uS/Hr. He had wiped down a small area of a wet car, and then tested the cloth. He indicated that this was above their normal background level. This was 2 days after my report.
I carried out a swab of a car windscreen after our first rain in weeks. I've been doing this every so often out of curiosity after seeing many videos on youtube showing results.Well, after 4-5 weeks of northerlies, and no serious rain (as well as stinking hot weather) a quick swab test of 0.4m^2 of windscreen yielded 0.33 microSieverts per hour ... outside background here averages 0.12 microSieverts per hour ...
Using the front foil, it appeared to be alphas and betas ...
What ever you were detecting blew this way, and precipitated in the rain.
I'm in Dunedin NZ. Almost 46 South

Here are four theories on what caused the spike in radiation.
My theory is that there was an event at Fukushima around late December 2011 - new years 2012 that released a large amount of radiation. The weather conditions where similar to those of March / April 2011. The (NILU), Norwegian Institute for Air Research had run simulations which predicted the creation of world wide radiation fallout clouds from the Fukushima nuclear disaster for March / April 2011. One of these simulations for March / April 2011 indicated that a radiation cloud would form off the east coast of Australia. This year the cloud formed again but blew inland, and didn't stay off the coast.
Here is the NILU map of the March /April 2011 radiation cloud off Australia's east coast.

Potrblog have gone to a lot of trouble, and put a detailed youtube video analysis of the Caloundra radiation spike event on the Internet. These people have done similar analyses of American radiation fallout events. This is their theory.

Here are new background radiation level charts that show raised radiation levels for January 25th, 27th and February 25th 2012.
This week starting January 23/01/2012, we have had over 300 mm of rain. Rain troughs have been coming from the Australian northern tropics constantly for days now. It would appear that our average daily background radiation is increasing since the spike event on the 8 January 2012, (see chart above).
I am now recording local background radiation every minute, so I am more likely to record those spikes. You will notice that the dark blue radiation average for 24 hours line in the new charts has crept up above 0.15 uSv/Hr to 0.18 uSv/Hr over the two days. Radiation spikes are now going above 0.3 uSv/Hr, plus background readings are much more volatile. Up until the 8th January 2012, I have not seen spikes go above 0.2 uSv/Hr at my location. These charts represents the highest average so far for the 4 years of data I have collected on local background radiation levels. Our average local background over four years has been around 0.10 uSv/Hr!
Another radioactive cloud passes over on the 25 February 2012, 24 hour chart - one minute sampling.
The highest recorded peak was 0.34 uSv/Hr at 7.33 am. More spikes of 0.30 uSv/Hr between 7am to 8am in the morning. Dark blue line in the 24 hour chart is the daily average, 0.146 uSv/Hr. This all happened at the end of a significant local rain event. Some local areas received 340 mm of rain in 24 hours.
I looked at the local weather radar at the time and the rain event came in off the ocean from the north north east. The same direction as the radiation cloud that I detected passing over the east coast of Australia on January 8th 2012.
Another radioactive cloud passes over on the 5th March 2012, 24 hour chart - one minute sampling.
The highest peak was a visual observation of 0.63 uSv/Hr after the Geiger alarm went of, lots more spikes of 0.30 uSv/Hr and above falling off in the late afternoon . Dark blue line in the 24 hour chart is the daily average, 0.185 uSv/Hr. This all happened during a significant local rain event.
I looked at the local weather radar at the time and the rain event came in off the Pacific Ocean in a strange spiral pattern from the north.
Radioactive cloud detections on the 20th and 21st of April
So far. all our radioactive cloud detections have occurred when the wind has come from the northern tropics. From my observations of the weather radar at the time, on the 20th and 21st, two air masses, a northerly and southerly, meet just north of Caloundra. The Geiger Counter alarm sounded on numerous occasions, indicating radiation levels went above 0.50 uSv/hr multiple times. These above 0.50 uSv/hr events where brief and were not recorded by the Geiger Counter data logger. My theory is that when the northerly pressure system pushed a little bit south, we got the radiation detections. When the northerly air mass was pushed north background went back to normal. The radioactive cloud detections are a result of the huge amounts of radiation released by the still active Fukushima Nuclear disaster, breaching the Northern and Southern hemisphere air circulation barrier.
Radioactive cloud detections on the 23rd of April
Here is the chart for the 23rd, peaks not as high as the 20th and 21st April, but the days overall average radiation level was higher.
