Qaqortoq (Greenland BACK ONLINE after Half Year Data Gap. Complete Gamma Record (EURDEP, Spring 2011-2016) & More

June 6, 2016


  • A fresh look at a very significant spike at Qaqortoq in August 2015 lead to a bit of a “walk in radiation monitoring land”…
  • There’s additional signs the jet stream was/is loaded with radioCesium and more…

Starting out with Qaqortoq, Sara, Southern Greenland. Click images for more detail:





-> the y-axis is changed from 160 nSv/hr to 240 nSv/hr, to be able to show the increased values




At the end of June 2014, the data processing is obviously changed, bringing the baseline back down, and narrowing the variability:






On August 25, 2015, there is a MASSIVE SPIKE (+27 µSv/hr), followed by disturbances:


Details of the spike:


A month and a half after the spike, the monitor is disappeared.  No data to be seen from early december 2015 till last week, early June 2016:


Clearly the widespread data gaps and spikes in Europe at the end of August 2015 had their origin most likely far west of Europe, beyond Greenland…

A look at the wind patterns on August 25, 2015, 12:00 UTC, 250 hPa:


I started out with adding arrows to the image below.  Then, to see if I would end up or pass over other specific nuclear sites, I turned te globe and turned arrows to the above screenshot.


–> As you can see, the southern side of the jet stream passed over Northern Japan, but not directly over Fukushima.   Directly upwind of the spiking monitor, one arrives much further north.  If you keep going, you’ll also pass over Western Europe (including France, Belgium & The Netherlands), merging more with that (grey arrow) core of the jet stream.

An extremely time-consuming process-of-elimination (of radiation monitors elsewhere) could help pin-point the source of this extreme radiation spike.

A peek at the week of that spike:


I’ll start in Greenland:  The data gap is shared by the two other monitors, but the spike is not visible in any way on the two more northern monitors (1 week data):


That French monitor on the Canadian Atlantic coast showed nothing:


On Spitzbergen, a Norwegian island in the Arctic sea shows a striking data gap right that week:


At that time, there was still one monitor left in Iceland.  It showed a clear uptick within a fallout-pattern-like disturbance period, with an earlier data gap.  Here shown together with a monitor in Luxembourg:


That spike in Europe is off-the-charts (well, I changed the y-axis so it’s ON the chart, non-validated like most its data, but… a MILLI-Sievert glitch dot?).  That’s extreme.

It was part of an apparent disturbance, with also data gaps in the months before and after:


If this connected somehow to the August 2015 radiological weirdness in Greenland, then there’s a possibility that it fits “my hypothesis about glitch dots”, which is that when hot volatile fallout moves very high up, it doesn’t affect ground monitors much, unless a hot particle directly hits such a monitor. The data then appears like an isolated dot, seeming like an instrument error, a glitch, so to speak.  Hence I call these “glitch dots”, but I consider them a possible clue to a higher-altitude manmade radioactive cloud.  

Because of its extremeness and it appearing part of a disturbance, I’m going to run another nullschool wind query for 250 hPa, for 49.6N, 6.0E on 1800 UTC Aug 22, 2015, and see where thát higher-up air might have come from:,81.42,512/loc=6.000,49.600


F1 = Fukushima (top left)

The usual result: the northern jet stream seems involved in the delivery of major fallout. 

You can see that shortly after that insanely high glitch dot, the jet stream slows down.  A look at two monitors in Southern Norway shows further evidence of that I might be on the right track:

showing a gradual increase that week, there’s a data gap that appears to be hiding a spike on Aug. 23-24 @ Oslo, Norway‘s Gamma record:


The monitor right next to it, @ Åsterås, Norway has radioisotope-specific data.  Here showing Be-7, for a clue of higher-up air coming down, and Cesium-137, usually a major component of a fallout cloud:


–> Cesium-137 spikes over 400% out of its normal (2015, nuclear era) variability, coinciding with a significant Berrylium-7 uptick.  You can see also that Be-7 is already rising the sample period before the Cs-137 spike, while Cs-137 doesn’t show much change yet.   The data gap nearby comes at the tail end of this Cs-137/Be-7 spike.

So, it seems the cause of the upticks and data gaps: 1) has a significant manmade component to it (yea, sorry excuse-producers, but volcanoes do not spew Cesium-137), and 2) is being delivered from higher up.  This is NOT “just surface dust blowing around”.  Just surface dust would neither be accompanied with such a major uptick in Be-7, which is naturally made by cosmogenesis in the upper atmosphere (or artificially as part of nuclear waste in a reactor), nor would it affect monitors on the same days thousands of miles apart.  That REQUIRES the jet stream to explain it.

Now I want to check a windmap and trace the downwind path and see how close I’d get to data-gapped Spitzbergen and mega-spiking Southern Greenland (less than 48 hours later.)

If you start on Aug 17 and move forward in time in 3-hour leaps, you see how one sample period includes a variety of conditions:,76.62,512/loc=10.267,59.133, including some that fit and some that don’t.

Elsewhere in Europe, there’s many more monitors that offer potential clues too. 

I start out with two Lithuanian monitors, but it turns out that those spikes have a typical pattern corresponding with a monitor calibration.  The minor upticks before occurred AFTER the spike in Greenland.  If there’s a connection then that COULD hint hint of the origin being more likely upwind of Greenland, with detections in Europe following.   A look at the other abnormalities could bring more certainty about that…



Latvia never disappoints:


-> 3 months @ Salaspils, Latvia shows possible fallout patterns both before and after August 25th, 2015:


This leaves increased room for a source in Europe, which would decend and hit ground monitors there and elsewhere on its later rounds around the hemisphere.

Continuing with week data in search of more potential clues:

Ampsin 3, not so far from Tihange / Huy, Belgium shows a significant uptick the day before:

NotFarFromTihangeIn a 3 month period, you see it is relatively unusual, and possibly part of fallout whiffs reaching ground level for weeks that summer 2015.  Hard to tell which of these are just radon progeny rainouts and which have an artificial part to ’em…


-> So, if I take that as “partially fallout”, then this would hint towards Europe’s upticks preceding the Greenland spike.

This next one shows 3 months from a monitor in North-Central France, with a 1 week insert.  Its data shows a “glitch dot” (isolated high value) of a whopping +720 µSv/hr on Aug. 25, same time as the Greenland Spike, following shortly after a data gap:


–> That’s striking, to have “glitch dots” on the same day in very different places (Greenland & France).  So if these are related, the higher-up fallout cloud could have been HUGE that summer 2015.

To be continued…

This blog post is just part of a set of “pieces of the puzzle” in my “data thriller series” about a MAJOR radiological emergency “mystery”.  

    I can only wish that it is somehow helpful

to bring a peaceful end to the misguided nuclear era.
