December 2014 Rain Water Test Report

 

Summary:

Lead Pb-210 and Beryllium Be-7, plus significant amounts of of Radon-222 and Radon-220 decay daughters were detected in the rain water and Rain swab tests. The trace amounts of Iodine-129 and  Uranium-235 are now below the detectible levels of the equipment here. The rain fall for the month was 92.4 mm.

In this chart I have CPS on the Y axis to show activity, and have turned off Y log to show linear scaling. It is on a scale at less than one decay detection every 1000+ seconds, near the bottom of the chart. This is only a test chart of the polyester part of the rain water filter system design.

December Rain Swab Test Chart:

Here is a 8th December 2014 rain swab off the bonnet of a car. The activity was ~ 1,600 CPM using the Theremino SBT-10 Pancake Geiger counter kit. The rain swab was immediately placed it in the scintillator test chamber. Lots of Radon-222 decay daughter activity Pb-210, Pb-214 and Bi-214 were detected. Look to the top of the chart to see the isotope peak, identification markers.

The grey line at the bottom of the page is test chamber background.

November 2014 Rain Water Test Report

Summary:

Lead Pb-210 and Beryllium Be-7, plus significant amounts of of Radon-222 and Radon-220 decay daughters were detected in the rain water and Rain swab tests. The rain fall for the month was very low at 5.2 mm.

It is on a scale at less than one decay detection every 1000+ seconds, near the bottom of the chart. This is only a test chart of the polyester part of the rain water filter system design. Tested both the charcoal and polyester components and there was not much difference in the isotope signatures captured. There was a slight difference in amounts detected in each filter type.

October 2014 Rain Water Test Report


Summary:

Traces of Lead Pb-210 and Beryllium Be-7 were detected in the rain water. This is surprising since the rain fall was only 30mm in October.

The Be-7 peak should be at 477 Kev. The  Be-7peak in this test chart with calibration is slightly to the left of the ideal at around 470 Kev. This suggests the presence of another unidentified isotope.  At these trace levels their peaks are too close for this equipment to separate the peaks enough to identify the other isotope. A second test was done a couple days later. Whatever was present had decayed away, and the Be-7 peak was where it should be in the chart.

So far we have not been able to qualify what the possible isotope maybe.

September 2014 Rain Water Report


Summary:

Significant traces of Lead Pb-210 and Beryllium Be-7 were detected in the rain water. Again this is surprising, considering the local background levels and rain fall were low for September. September 2014 had 63.2 mm of rain. There were a number of significant solar storms and CMEs which hit the Earth's upper atmosphere in September.

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.   My view is that because of the upper atmosphere damage, and a weaker magnetosphere, smaller solar events are now having a greater impact on the Earth's upper atmosphere. This is a possible explanation for the increased Beryllium-7 detections in rain water washouts here.

August 2014 Rain Water Test Report

 

Summary:

Significant traces of Lead Pb-210 and Beryllium Be-7 were detected in the rain water. This is surprising considering the local background levels were so low for August. August 2014 had 209.6 mm of rain compared to July’s rain fall of 14.5 mm, so a lot more rain flowed through the filter this month. 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.  Because of the upper atmosphere damage, and a weaker magnetosphere, smaller solar events now have a greater impact on the Earth’s upper atmosphere. This is a possible explanation for the increased Beryllium-7 rain water detection here in August.

July 2014 Rain Water Test Report

Summary:

Even thought the roof rainwater water collection area that passed through the polyester filter has been nearly doubled this month, there were only been very small traces of I-129, Pb-210 and Be-7 detected. July rain fall was also low at 14.5 mm.

May 2014 rain water test report

 

Summary:

May 2014 had 145.6 mm of rain. The test chart shows the presence of mainly Pb-210 and Beryllium Be-7. Less I-129 this month, plus possible traces of Uranium U-235? In this chart I have CPS on the Y axis, to show activity, and have turned off Y log to show linear scaling.

April 2014 rain water test report

 

Summary:

This filter had a lot of green algae growing in it by the time I tested it. The chart is minus background, and is using CPS for the y axis. Testing time was 24 hours. As you can see, there are clear peak markers for Beryllium Be-7, and a combination peak of Iodine I-129 and Lead Pb-210.

 

There was more Be-7, I-129 and Pb-210 detected in April’s test compared to March 2014. Interestingly, March had more rain, 204mm compared to April’s 171 mm. This suggests there was a lot more Be-7, Pb-210 and I-129 in the atmosphere here in April, compared to March 2014.

March 2014 rain water test report


Summary:

It was a fairly wet month with 204mm of rain, so a fair bit of rain water flowed through the filter. The main isotopes detected were Iodine I-129, Lead Pb-210, and Beryllium Be-7, with possible traces of Uranium U-235?. There was more rain in March 204mm, but less detectable traces of isotopes than February. In February we had 37mm rain. This is chart using a new background, recorded on the 21st March 2014.

February 2014 rain water test

 

Summary:

It was a dry month with only 37mm of rain, so not much rain water flowed through the roof down pipe filter. Traces of Beryllium Be-7, Iodine I-129, Lead Pb-210, and Uranium U-235? were detected. The main Isotopes Be-7, I-129, and Pb-210, detected, seem to be in significant amounts, taking into account the amount of rainfall we had here for February.

 

Be-7 can be created naturally by spallation, from solar wind and upper atmosphere interaction. The Sun has been very quite at recently. There was some significant solar activity towards the end of February, but it takes around two weeks for any Be-7 created by this process to reach the lower atmosphere.

 

A theory proposed by a contact:

“One could speculate the increased production from solar variation, however, it is most likely from Boron neutron synthesis.”

 

The theory is that lots of Boron has been used to control the meltdowns at the Fukushima Nuclear Disaster. Neutron bombardment of the Boron from the molten Coriums is creating lots of Be-7, which is being released into the atmosphere.

Caloundra January 2014 Rain Water Test Results - It was a relatively dry January, so not much water flowed through the polyester rain water filter.The rain water filter test main peaks are for trace amounts of Iodine I-129, lead Pb-210 and Beryllium Be-7. There is a natural Beryllium Be-7 and Lead Pb-210 cycle here in the Southern Hemisphere. More Beryllium Be-7 and Lead Pb-210, is detected in rain washouts during summer, than in winter.

Is it all natural, or is some from Fukushima, that is the question?


I am suggesting that the peak at around 80 keV is test chamber Lead fluorescence, caused by the Be-7 Beta radiation released from Be-7.



Caloundra 6th January 2014 – A rain swab was taken off the bonnet of a car,  on the 6th January 2014.  It was tested for 7 hours using a Theremino Geiger counter kit, using a Russian SBT-10 pancake probe. Initial peak was around 5 uSv/hr 3,000 cpm.  The rain swab was placed in a zipped lock plastic bag, so this was only a Beta / Gamma test. This is the second hottest rain washout detected here so far. The Geiger counter decay chart of the rain swab showed classic Radon-222 decay daughter decay.

Here is the scintillator test chart preliminary assessment, of that rain swab. Experimental MCA Theremino V6.2 software was used for this test. It can get a bit noisy near background. This experimental software is pushing the limits of what can be detected with the equipment here. Peak markers are at the top of the chart for reference.

The rain swab Geiger counter and scintillator tests showed that the rain event on the 6th January was mainly Radon-222, and Radon-220 washout. You can see some of the peaks for Radon-222 and Radon-220 decay daughters still present in the test chart. The main peaks are for Radon-220 daughters at, Pb-212 X-ray (77 kev), Lead Pb-212 (238 keV) and Tl-208 (583 keV). There are possible traces of Iodine I-129 (40 keV)?, Lead Pb-210 (47keV), U-235 at (185 keV)?, and Beryllium Be-7 (477 keV). The peak between the Be-7 and 511 peak markers is probably a sum peak of the two. Here is an alternative detailed analysis of this rain swab scintillator test.
