[ RadSafe ] Fwd: [New post] The spread of particles with plutonium and cesium, from Fukushima nuclear fuel

Sat May 21 11:49:15 CDT 2016

Sorry Mattias and Roger,
Sorry, you are completely wrong. Those were beyond doubt hot particles. We 
saw on radioautographs of our routine airfilters only a few days after the 
Chernobyl accident very prominent black spots, some very "large", most tiny. 
We were not the first to find them and not the only ones. We didn't have the 
equipment and not any seconds of time during that superhectic situation to 
analyse them for the radionuclides causing them, but some others did, for 
instance Rolf Falk at the Swedish Radiation Protection Institut (SSI) who 
showed them to me when I was on a personal visit in Stockholm. Those hot 
particles were of different composition, including fuel particles but not 
exclusively plutonium, depending on the phase of release, and obviously on 
the temperature. Since both Sweden and Austria are quite far away from 
Chernobyl (Tjernobyl) I would not be surprised to find hot particles shortly 
after the accident somewhere far away from Fukushima. There is a difference 
to Chernobyl: The latter was burning thanks to the graphit for about two 
weeks, resulting in much higher emissions. BTW there was some time a hype 
about hot particles but it decayed rather soon. I suppose that Rolf might be 
retired , but if you have contact give him "mina vänliga hälsningar"!

Regarding the Wikipedia paper: I would not sign all of it, but compared to 
what is written in Austrian papers it is an "excellent scientific paper". 
Not to talk about the propaganda spread by various groups like "mothers 
against nuclear power" or disgusting most of all a highly commercial and 
criminal group who thinks it is their right to break any national or 
international law, to commit crimes by putting people at deadly risks, to 
attempts causing heavily damage to other persons equipment distributing 
paranoia - all under the banner of "environmental protection". They urge you 
by stopping you almost brutally on the street to donate money to subscribe 
to dubious journals.

Sorry I got carried away - I do not like to be called a massmurderer who is 
bribed by the nuclear industry......

Best regards from a now sunny and warm Vienna!

Franz

"Everything I’m finding here is millions and billions of very, very
small particles that are spread pretty much everywhere."

Could it be...atoms? :-)

The Wikipedia page on radiation effects from Fukushima puts these
numbers into perspective, see the section "Plutonium isotopes"
https://en.wikipedia.org/wiki/Radiation_effects_from_the_Fukushima_Daiichi_nuclear_disaster

Does any of the experts here have any comments on what is written on the
Wikipedia page, any errors or things worth adding?
