Two uses of 106 eye melanoma treatment and satellite power. Could it be from a sat breaking up in atmosphere?
Very doubtful. That would have been reported.
Makes sense
An attempted launch of a satellite that exploded on the launch pad, maybe?

Two articles follow up on this incident. One from The Sun and one from Russia Today.

I am presenting both to give both sides of the reporting.
VLAD NEWS Scientists puzzled as Europe is mysteriously showered in radioactive particles…and they think it came from Russia

German scientists say there has been a slight increase in the amount of particles of the isotope Ruthenium-106 in Germany, Italy, Austria, Switzerland and France
https://www.thesun.co.uk/news/4659356/s ... om-russia/
Germany’s Office for Radiation Protection reported increased radioactivity in parts of central and western Europe over the past week. The heightened levels were detected at several trace measuring stations in Europe, and at six locations in Germany.

The particles are ruthenium-106, an isotope used in radiotherapy for eye tumors, and at times in radioisotope thermoelectric generators (RTGs) which provide power to satellites. An increase of ruthenium-106 has been detected in the air in Austria, France, Germany, Italy and Switzerland.

UPDATE:

The French Nuclear Safety Authority has now published their result of the investigation:

Image
For the most plausible zone of release, the quantity of Ruthenium 106 released estimated by IRSN simulations is very important, between 100 and 300 teraBecquerels. The release, accidental with regard to the quantity released, would have occurred during the last week of September 2017.

Because of the quantities released, the consequences of an accident of this magnitude in France would have required to implement locally measures of protection of the populations on a radius of the order of a few kilometres around the location of the release.

So would this have been a possible Nuclear test or a Nuclear failure? Such as chernobyl?

Almost certainly a nuclear accident of some sort, not a weapons test. No one can conduct an underground nuclear weapon detonation anywhere on the planet without seismographs picking up on it immediately.

Maybe..
Following Putin’s speech, numerous US experts told media that they were aware Russia’s attempts to build something like what he described in his speech: A nuclear missile powered by an onboard nuclear reactor. The United States tried – and failed – to deliver something similar in the late 1950s.

The experts went on to tell ABC television that Russia has, in fact, been dabbling in something like this, but that Moscow’s version has been crashing over and over in the Arctic.

They didn’t supply a timeline for the crashes. But Bøhmer suggested that two incidents of iodine 131 pollution measured over Northern and Central Europe between January and March of 2017, and again in January and February this year, might have some connection to those possible wrecks.

The levels of iodine – which has a half life of only eight days – were picked up in both cases by measuring stations in Finland and Norway, which, of course, both abut the Arctic.  In the earlier event the releases were confirmed by Poland, Germany, the Czech Republic, and France as well.

In the event of some sort of nuclear test, says Bøhmer, particularly in a country where nuclear safety wasn’t much of a concern – and both the Russia and the US have a dark history here – iodine could, as it has during nuclear tests in the past,  show up in the atmosphere, along with a host of others isotopes on top, such as strontium and cesium.

Neither of these last two isotopes, which have a half lives measured in decades, showed up in the detected releases of iodine. But Bøhmer suggests that the Chernobyl disaster in 1986, which released massive amounts of both isotopes into the environment, could serve to mask their detection in the recent batch of readings.

On both occasions – and unlike the recent detection of radioactive ruthenium, in which Russia’s nuclear reprocessing facility Mayak remains a prime suspect – there were no culprits who could be traced to the not unhealthy but certainly suspicious blooms in iodine 131.
