High Radioactivity over the Urals
Is this anything to be concerned about. I have a flight in a few days across Russia....
Russia finds 1,000-times normal level of radioactive isotope after nuclear accident claims.
Russia's meteorological service said on Tuesday it had measured pollution of a radioactive isotope at nearly 1,000 times normal levels in the Ural mountains, the first official Russian data supporting reports that an accident had taken place.
The data appears to support a report by the French nuclear safety institute IRSN, which said on Nov. 9 a cloud of radioactive pollution over Europe had indicated that an accident had taken place at a nuclear facility either in Russia or Kazakhstan in the last week of September.
Neither Russia nor Kazakhstan has acknowledged any accident.
Russian state weather service Roshydromet said in a statement it had found "extremely high pollution" of ruthenium 106 in samples from two meteorological stations in the southern Ural mountains region in late September and early October.
At the Agrayash weather station the levels were 986 times those of the previous month, while at the Novogorny station they were 440 times higher. The weather service did not rule out that the radioactive isotope could be absorbed into the atmosphere and reach Europe.
The Agrayash weather station is located about 30 km (20 miles) from Mayak, a huge plant that reprocesses nuclear fuel and produces radioactive material for industrial and research purposes, owned by Russian state nuclear company Rosatom. Mayak accounts for half of Russian exports of radioactive isotopes.
In a statement, Mayak denied that its plant was the source of increased level of ruthenium 106. Rosatom was also quoted by Russia's RIA news agency as saying there were no accidents at any of its facilities which could increase the level of ruthenium 106 in the atmosphere.
Greenpeace said in a statement on Tuesday that it would ask Russia's prosecutors' office to investigate whether there had been an accident in the area.
"It also demands a check into whether the atmospheric radionuclide monitoring system is sufficiently prepared for possible accidents, and whether public health around a possible release of Ruthenium 106 was sufficiently protected," the environmental pressure group said in a statement.
France's IRSN ruled out the possibility of an accident in a nuclear reactor, saying the material it detected was more likely to have been released from a nuclear fuel treatment site or center for radioactive medicine.
The pollution would not be sufficient to cause an impact on human health or the environment in Europe, the French institute said.
The Institute of Nuclear Physics in Kazakhstan, which neighbors the southern Urals, has said there were no accidents at its scientific research reactor and no ruthenium 106 at its two disused testing areas in western Kazakhstan.

Ruthenium 106
Apparently a result of a mishap at a nuclear waste reprocessing facility - but no official announcement. Ruthenium 106 apparently has a half life of 15 days and would only have been of concern close to the source.
Should pose no risk to your flight.

Follows on from a spike in Iodine-131 back in Feb (Mysterious radiation spreading across Europe after authorities keep it secret | The Independent) and Ruthenium-106 in Sept (https://phys.org/news/2017-10-spike-...ty-europe.html).

Levels of it high in the air are very low, so don't worry about the flight.
Problem is radiation is a much a "trigger" word
True, and with that mind we should be aware that mammothskier makes a valid point...
It certainly should "bother" you, or at least be of interest to you if you live in certain parts of the world...(..e.g. Anyone else here ever lived in an area with granite bedrock, perhaps in a house constructed on granite.?)
As a professional pilot you should be aware of the risks of radiation.
Ground-level radiation isn't what should bother you.

106Ru half life is 373.59 days, not 15, but it emits beta particles (electrons) that don't travel further that a few centimeters, so you need to have it on your body to be dangerous.

Looks like an incident at Marjak.

The nature of these beta emitters means that even a single particle breathed in COULD cause health risks.
Can we do anything about it / Is there cause to worry? - Probably not, its already spread, and we found out much later than the accident (that Russia are not even officially acknowledging).

Can you recommend any (online) reading that might dispel the myths about radiation and particles?
My knowledge jumped from Dan Dare's ray-guns to the radiation teaching issued by the Air Training Corps in the late 1950s (when we were all going to die) . . .

You could start with Wikipedia https://en.wikipedia.org/wiki/Radiation
The fact is though we all live with radiation every day, especially pilots and CC. For example my yearly allowed dose in my work environment is 50uSv, which is less one trans-Atlantic flight at 80uSv.
https://www.gov.uk/government/public...se-comparisons
Most people are unlikely to get any Gamma dose (except in hospital under controlled conditions) but the nasty stuff are the beta and alpha emitters, these would be produced in nuclear tests, accidents such as Chernobyl and the one we are discussing. Very small fragments of active material can be ejected and travel a very long way as aerosols.
Have a read about Downwinders https://en.wikipedia.org/wiki/Downwinders
But there are a lot of factors:
- What elements/half-life - If short not much risk, its decayed before reaching anyone
- How far will it spread? wind, weather, remote location..
The health risk, the risk of a cancer depends on: how much is inhaled/eaten, the level of activation, how much it has already decayed and how long it stays in the body.
My point was its not impossible that one could encounter some of this material via flying through it. But the fact is it had already passed over Europe albeit in small quantities before we ever found out. And ref above we have many sources of radiation in our everyday lives, you just cant avoid it, so at least in my opinion its not worth worrying about.
(The exception to that is Radon, always worth finding out if you live in a susceptible area and taking precautions, because you can do something about it)

The mystery is possibly solved!
It turns out Putin has testfired a atomic powered cruise-missile last year.
He was just on TV yesterday bragging about this and a few other ingenious gadgets his Boffins has concocted!
I never thought I was going to miss Leonid Bresjnev and the cold war,,,
MAD at least gave some predictability and stability.
Now its just Madness.
Good luck to us all!
