Apologies.

Mrs Currawong had an incident with the Sunday brunch bacon.

Did not think it merited a Notam...

This is how fake news are generated and spread, intentionally or not.

Now read the source, the Dutch agency - https://www.rivm.nl/en/news/radioact...orthern-Europe

Note: Some recent media reports claimed, possibly based on a mistranslation of our original report (in Dutch ), that the radionuclides originated from western Russia. The claim RIVM makes is that the radionuclides travelled from the direction of western Russia to Scandinavia, but that no specific country of origin can be pointed out at this moment.

There are quite some atomic plants in the area (Sweden, Finland, The Netherlands, Germany, UK) and also the prevailing air transfer is from West to East, so check twice before blaming anybody....

Much smaller footprint than that. In such cases attention turns to the usual culprits, unjustly or not......

More importantly, from analyzing the radionuclides they suggest it was likely released from a nuclear reactor.Iodine-131 was detected in Norway, while cesium-134, cesium-137, cobalt-60 and ruthenium-103 were detected in Sweden and Finland. The amount of radioactivity was very low and there was no impact on the environment or human health. No artificial radioactive substances have been found in The Netherlands. RIVM National Institute for Public Health and the Environment continuously monitors the presence of radioactivity in The Netherlands. Detecting very low levels of radioactivity (such as in this case) is only possible with advanced equipment. Such equipment is available at RIVM.
Possible cause and source
The detected radioactive substances are artificial. The combination of radionuclides may be explained by an anomaly in the fuel elements of a nuclear power plant. RIVM has performed calculations to find out the source of the radionuclides.

And
Note: Some recent media reports claimed, possibly based on a mistranslation of our original report (in Dutch ), that the radionuclides originated from western Russia. The claim RIVM makes is that the radionuclides travelled from the direction of western Russia to Scandinavia, but that no specific country of origin can be pointed out at this moment.

A similar situation occurred in 2017: radioactive ruthenium-106 was found in the air in several European countries. Because many more measurements were available then, RIVM was able to locate the source more accurately. The calculated source was in excellent agreement with an existing nuclear facility that was pointed out as the most probable source in multiple international investigations.

Two questions to A Van.
1. Despite the prevailing winds, in which way did the radioactivity travel around Europe after Chernobyl?
2. Who in the general area does not have a good reputation for coming clean about past releases, apart from the UK?

Looking at that map ... when you release something like a gas, doesn't it start out as a small stream and fan out to something larger?

...rather than a big blob that becomes something narrow?

1. Chernobyl was not a spike, but a continuous process lasting for a few days. First few hours the wind blew to the North, contaminating southern part of Belarus. Then it was changing affecting both north-west and north-east sectors (the latter impacted RF territory). But the main thing that matters is where the radioactive cloud starts raining. It may pass the neighboring region leaving it nearly clean, while making remote areas quite dirty. It happened exactly like this in 1986.

2. Reputation is quite a subjective thing, greatly affected by media. But in general it is Ukraine, no doubt. Especially after they started replacing Russian fuel by the units developed by Westinghouse. There were several quite dangerous incidents. Now some reports say that the situation improved but many experts are still concerned with risks.

Thinking just that myself..the narrow plume seems to be aligned with the Hartlepool, Heysham and Sellafield facilities. May just be co-incidence though, with only one monitoring station in the plume, it's surely difficult to be more precise.

Hi A_Van, could you expand a little on that, I don't quote understand your meaning. Are you saying the Westinghouse fuel caused the incidents?

...
Because nuclear fuel is different

The diagram isn’t a plot of the plume, it’s a plot of the area of highest probability of the source based on the prevailing winds in the previous 72 hours based on the location of the sensor (SEP63).

I did not say the fuel from W was bad. It simply did not suit particular reactors that were used in Ukrainian power plants.
Once (in 2012 in South Ukrainian power station) its use even led to deformation of fuel cassettes so that the reactor(s) had to be stopped, some units taken out, etc. It took quite some time and cost some USD 175M in total losses (for a relatively poor country it really matters). Also problems were reported in 2013, 2016, 2017.
