I'm in Germany and I have a Geiger counter running 24/7. I just looked at the data for January and February and the only thing that I notice is a VERY slightly higher reading on February 4th with 0.1727 microSievert/hour. Average for January was 0.1674, lowest was 0.1631, highest was 0.1703. So February 4th was less than 6% higher than the lowest value from January.

The difference was so small that I had just attributed it to normal fluctuations when I first saw it. Whatever caused this, so far it looks like it was a very small event.

I could probably provide a CSV-file with the raw data if anyone is interested. My Geiger counter stores a value every 5 minutes.

Could it be related to the accident in France? The date fits.

Tab-delimited CSV with the raw-data:

The timestamps are in UTC+2. I keep the clock in the Geiger counter on daylight savings time. Too lazy to change it. :)

Out of total curiosity what does your setup look like? Do you have a mode # of what you use? Never read anything about this before. Thanks.

Not sure about Op's setup, but an easy one to get into is uRad[1]. Along with logging it'll share it around the globe for finding any kind of event like this. Though I'm not sure that they've got any kind of statistical analysis going on.

How expensive are those sensors?

Their indiegogo put it at $90 for a kit to solder, and $120 assembled. No idea what the cost is now since you've got to email them on their website to get one it appears

I have the GammaScout Alert: https://www.gamma-scout.com/EN/Home.php

It stores the data in its internal memory which I then transfer via its USB port to my computer once a week.
