Any new info on "hot particles"?
The last time uncle Arnie used the phrase he mentioned "cesium, strontium, cobalt, and many, many, more"....
This has been really bugging the hell out of me. Are we getting all worked up about a molecule of Cs? Is radon a hot particle? How about I-131? Be-7?
Let's cut the crap. I want to see some data. I know science takes time, but I am beginning to think that there has been some sensationalism here.

You may find this interesting. Probably not his main research but it's something:

Thanks! So he has picked up
Thanks!
So he has picked up on cesium and uranium in air filters from Japan. No surprise there.
Has anyone here stateside tested a vehicle air filter?
And is anyone out there aware of any further research done on the supposedly hot air in the Northwest?
Hey, for anyone lurking on
Hey, for anyone lurking on this thread - this info on Japanese air filters is coming from Marco Kaltofen, the scientist from one of the early Fairewinds vids. If you go to the link, it shows that cesium, cobalt, uranium were all detected in the air filters.
At least this gives us some idea what a "hot particle" is - they are evidently NOT using this term to refer specifially to alpha-emitters (ie, Pu and U) but to basically the whole alphabet soup of radioactive garbage.
I am leaning towards the "hot particles" issue being one of semantics. For example, who here was thinking that if there cesium and such in the air that they would somehow not inhale said particles, albeit in very small quantities? But call it "hot particles" and all the sudden we are thinking that a person may have inhaled 5 specks of plutonium or americium every day in April - that's scary, right?
It also puts to bed the issue of whether or not BRAWM has detected these hot particles....hell yes they have. That's what they have been counting all along.
Mark, love to hear you chime in on this.
Some comments from Mark on this
Mark responded to another thread about how "hot particles" are diffferent.
You can see this (as well as other comments from Mark) in the following link:

From my understanding of what Mark is saying, they would certainly be able to detect the activity of hot particles that include cesium and the like. But, identifying them specifically as "hot particles" is not straight forward.
Got it. They are looking at
Got it. They are looking at activity, not at whether that activity is from a hundred indvidual molecules or one good sized chunk.
Has Marco Kaltofen defined "hot particle"?
And does anyone here have a grip on the physical properties, especially size, of the fallout?
Supposedly in Seattle his
Supposedly in Seattle his team detected half the levels detected in Tokyo? (10 Vs 5 "hot particles") If the activity detected in air filters from Tokyo is 0.2 micro-sievert/h, in Seattle it would be 0.1? Isn't that very close to background?
"Background" is 1 particle
"Background" is 1 particle every 2 days, so 5 "hot particles"/day is 10 times normal.
Yes, any further info/input
Yes, any further info/input would be appreciated re: hot particles in vehicle air filters/pollen filters over here on the West Coast of US and Canada. Also, are 'hot particles' still being detected now in June? Or were they only really an issue back in March/April?
Thanks!
just a friendly reminder
just a friendly reminder that much of the west coast was not affected as badly as some midwest and east coast areas (i.e., radiation detected in Mass milk and Florida got quite a dusting) due to the jetstream flow.
It's all about the jetstream, not necessarily proximity.
Wind and Rain
Wind and Rain are key players in radionuclide storms.
The wind delivers the nuclear fallout to your latitude and longitude, from ground level to approximately 50,000 feet. Some of the radionuclides will settle to earth as dust.
Rain forms and cleans the air and washes the radionuclides to earth. The surface concentration is increased dramatically as a result of this 'Black Rain'.
The deadly phenomenon of 'Black Rain' was first documented in several Japanese cities, following the nuclear bomb attacks on Hiroshima and Nagasaki. A number of 'Black Rains' were documented during atmospheric weapons tests. Boston and Boise provably received 'Black Rains' from Fukushima. No doubt there were many others, given the massive radioactive fallout from three (3) reactor fuel meltdowns. Reactor-3 is/was MOX fuel, a particularly nasty plutonium/uranium mixture.
