Could this possibly be the result of damage to a Ukrainian nuclear power plant during Russian's recent incursions?

There are no nuclear power plants in areas of Ukraine that are affected by the conflict. The closest one is the Zaporizhia Nuclear Power Plant, but it's located in a stable area with no current military activity. Other three are further to the west and equally unaffected.

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 attribu…

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.

Can someone describe the significance/insignificance/context of this?

The ISRN appears to be a French government agency. They are claiming to have detected non-natural levels of radioactive iodine across Europe. The implication is that someone, somewhere had a nuclear accident and did not report it.

There was a recent incident in late Jan - explosion at nuclear power plant Flamanville in France: https://www.wsj.com/articles/explosion-at-edf-nuclear-power-...

> The detection of this radionuclide is proof of a rather recent release.

Three questions

After rain?

Could be Iodine being generated directly in place from other compounds or being seeded by suspended dust in clouds?

Could be this "Ukranian war" related?
