March 15, 2015: Since exactly four years ago on March 15, 2011, just four days after the triple meltdowns at Fukushimi Dai-ichi Japan began, EnviroReporter.com has produced more than 7,322 special tests and original reports including 2,819 measurements and analyses from nine affiliated Radiation Stations and 4,503 samples and radiation experiments from Radiation Station Santa Monica California. EnviroReporter.com has over 1,890,968 readers and 1,572,073 viewers along with the 21,130 people who have seen Radiation Station Glendale California‘s continuous online streaming. Over 190,172 viewers have watched 90 original videos on our YouTube channel and we’ve received tens of thousands of Facebook ‘likes’ for our site, investigations and Facebook channel. Thank you for your support as we celebrate these milestones on the Ides of March.

Southern Hemisphere February 2015 Background Radiation Report.

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

February 2015 Background Summary

Pretty much the same as last month. We see a drop in the month average background level for February 2015, and the rain water test shows manly Beryllium Be-7, and Lead Pb-210. The traces Iodine I-129 and Uranium U-235 showing up in the previous years rain water tests, are now below the reliable detection levels of the equipment here.

The good news is that background levels here have stabilized, at least at this location in the Southern Hemisphere. I still detect the occasional event. These detection events are generally not as large, or as frequent as previous years.

February 2015 monthly average background radiation level was 30% above the pre-Fukushima average.
February average for 2014 was 40% above the pre-Fukushima average.
February average for 2013 was 39% above the pre-Fukushima average.
February average for 2012 was 37% above the pre-Fukushima average.

Technical details:

(Note: The 4yr average referred to in the charts, is the 4yr pre-Fukushima
average.)

February 2015 Rain Water Test Report

Summary:

February rainfall was 426.6mm.

Beryllium Be-7 can be made by spallation in the upper atmosphere, during solar events, and takes around two weeks to reach the surface. Lead Pb-210 is a decay daughter of Radon Rn-222. Both these isotopes can also be released from a
Nuclear accident.

Rain Filter Test Chart (The chart is minus background.)

In this chart I have CPS on the Y axis to show activity, and have turned off Y log to show linear scaling. This is only a test chart of the polyester part of the rain water filter system design. The Polyester filter actually captured more than the carbon filter.

Do cyclones draw Fukushima radioactive air contamination through the equatorial barrier, into the Southern Hemisphere?

Caloundra (Queensland Australia) 22th February 2015 – The remnants of Tropical Cyclone Marcia came and went, the day average background here actually dropped then rose.

http://sccc.org.au/wp-content/uploads/2015/02/Caloundra-local-average-background-radiation-levels-February-2015.jpg

The dip in the day average occurred a day before the degraded Cyclone Marcia was closest to here. We had around 330 mm rain over a few days. This suggests whatever was in the air was being washed out.

Geiger counter testing of a car bonnet rain swab collected on the 20th, 630 cpm or ~1.0 uSv/hr. Not nearly as high as other rain event tests.

When placed in the scintillator there was very little Radon-222 present, again not nearly as high as previous rain swab tests. The rain swab is also not showing any significant Be-7 or Pb-210, as recent rain test have shown. Radon levels were low averaging around ~ 0.5 pCi/l over that period. As the tail of Cyclone Marcia left the area we had a wave of radiation pass through. Haven’t seen this type of radioactive cloud stand out event since late 2011, 2012, and 2013.

Here is the 24 hour chart.

(Caloundra is in Southern Queensland and Cairns is in Northern Queensland Australia.)

Report from a contact near Cairns in North Queensland, 20th February 2015

“I would like to report an unusual event yesterday. Yesterday 20. Feb 15 between 17:00 and 18:00 the alarm set at 0.400 uSv on my Gamma Scout kept sounding continuously. The daily average reading after midnight was 0.167 uSv, a value, that I have never had that high since I started using the instrument about a year ago. As per this morning, the readings still persist around the 0.150 to 0.160 uSv mark. There does not appear to have been any serious solar events. The weather here has been sunny, up to 33 C hot and humid.”

Category 4 cyclone Lam also hit the Northern Territory of Australia, as category 5 Tropical Cyclone Marcia hit Queensland Australia. For two cyclones to hit Australia at the same time is very unusual.
