Probably not actually - Pu has an extremely long half-life (tens of thousands of years), which means it emits very low levels of radiation. You'd need something with a very short half-life, like Po, to get dangerous doses from a few specs.
Well Polonium is certainly really bad.
Not all isotopes of Pu are so long lived. Yeah one is tens of thousands but others are thousands and another is only decades. Although I guess the reactor would use the long half-life one. But that doesn't mean that that isotope is low in radiation, it's still pretty high as things go. And alpha radiation can be 100-1000x more damaging. The long half life means it takes ages to go away.
I could swear I've read that Plutonium was considered one of the most dangerous to be exposed to. (EDIT: apparently the hot particle lodged in lung theory appears to be false since the particles have proven to be more mobile than originally thought and the risk vastly less than originally thought. High doses inhaled are significant risk though due to collection in liver and bones (even just 20mg would be VERY bad in even relatively short time, so it depends what you mean by specs). So it's very dangerous and yet in most scenarios it's not like you'd ever get exposed to more than tremendously small amounts though, vanishing specs, since most release scenarios give super low concentration exposures.)
Of course in this particular case the concentration would be super low into the air even right in Japan in closer areas they expect people to inhale less than .0001mg and it's not the particle that got blown all over and dispersed more by the steam explosions, those may do the greater harm there, since the general plutonium release across Japan appears to be barely greater than whatever background dust already there, so the degree of specs in this case would be nothing, but in the general case of talking about specs it depends what you mean by specs, a spec can be a lot, lot bigger than .0001 mg worth, it's a vague term.
Interesting after one year camera grip will become white? What exactly they might do to for repair? Spray with black paint, use black tape or replace to new case/grip?

Nope. You could call it "self-insured" at most, because it is simply written off as an expense. It is paid out of cash reserves.
Big companies do not buy insurance for ordinary business expenses. Canon will take back the 60,000 or so affected cameras and still make an overall profit on the T4i line of cameras, which will probably sell several million copies.
Canon sells about 17 million DSLRs a year. 60,000 are a drop in the bucket, less than half of one percent.
I mentioned radiation because the Russian customs were checking and stopped some Japanese cars from entering the country.
I don’t believe the public was ever told about the real radiation levels from Fukushima.
As to T4i I don’t see it as dangerous. The Zinc White paint is still manufactured and used daily by many painters.

the tamron 28-75 starts turning hints of white after a few years
Canon U.S.A., Inc. has received one report (out of 68,000!) of a consumer who developed a minor rash after contact with a surface where the camera had been
I don't get it - a single person got a minor rash by being in contact not even with the camera but with a surface where the camera had been

So imagine how much worse it could have been if that person had actually come in contact with the camera. Contact dermatitis can be more serious than just a minor rash.
I suspect that Canon subcontracts with multiple sources for the grips, and one of the suppliers wasn't following the guidelines. Melamine in baby formula? Cadmium in jewelry? Lead in dishware? It's becoming all to common these days, and one country leads the way in these incidents.

That's because we get all our stuff made in the same country, not because that country is somehow morally more corrupt than any other. Statistically it leads the way in everything manufacturing related, including building really good stuff too....

I totally disagree. The Chinese in general (and of course there are exceptions) do not have the same regard for intellectual property rights, consumer safety, and workers' protection as most other industrialized nations.

But my camera has been on god knows how many surfaces in my house. Should I burn the house now?

Be careful where you point your finger - none of us live in countries with a spotless record on this.
As for intellectual property rights, well P2P traffic is ~13% of all traffic in North America and around 30% in Europe. I think we have to be honest and admit that most of that is movies and TV programmes. So there goes our moral high ground on that. Consumer safety and workers' protection in every western country only occurred following decades of abuse post-industrial revolution (and are still not eradicated). Relatively speaking China is actually well ahead of the curve on this.
Then we can move onto the systematic mis-selling of mortgages to people who clearly couldn't afford to repay. Five years on i'm not seeing anyone go to jail for this in the name of "consumer protection". The fiddling of inter-bank lending rates. The dumping of toxic waste off the east african coast by mafia-run "waste disposal companies". Trafficking and exploitation of immigrants throughout the western world. The list could run for pages.
Certain facets of human nature transcend cultures, creeds and religions. Greed is the big one, and we're all every bit as guilty as any other culture. It is willful ignorance to think otherwise.
Make sure you enter the full camera's SN on canon website. Initially, it was reported that the affected cameras are those with the sixth digit = 1. However, it's been changed recently. For example, even that my camera has 1 for the sixth digit, the site reports "Not affected".
Phew, I was worried that I can't legally cell my house.

Yes, but then you still must hold Canon responsible as they are subcontracting this out. It is there responsibility to ensure all standards are followed. Too easy to blame someone else. Buck stops with Canon on this...period.

"It is illegal to resell or attempt to resell a recalled consumer product." So does this mean that if anyone doesn't send it in for the recall fix, then sells it on the B&S, etc., that they're breaking the law? Sounds like it...
The CPSIA law, passed by GW Bush in Aug. 2008, was intended more for children 12 and under, mostly baby gear containing lead paint or other dangerous substances or product deficiencies. The Canon Ti4 recall is no different than an automobile recall. They fix the problem, you keep the paperwork to show it was fixed. Guessing what chemicals could have caused an irritation is just speculative. Canon will survive.

I thought of radiation when I saw this too...and it is a very valid concern for any product coming from Japan. From food to cars to cameras. The Fukushima disaster is far from over, with ongoing releases of massive amounts of radiation in to the ocean and atmosphere. With the potential for it to become dramatically worse if the spent fuel pool #4 collapses.
The chart posted by Monito...although I imagine well intentioned. Is very misleading. Normal background radiation does not contain radioactive isotopes like plutonium (a large amount of which was released by Fukushima). If you ingest one of these particles, that is where the trouble lies. These "internal emitters" are what cause all the mutations, cancers and diseases.
Right now they are reporting deformities and mutations of insects in Japan. (It's worth remembering that insects by and large are more resistant to radiation than humans).

There is only one reason why the Russians customs were stopping the cars from Japan and I can assure you the radiation concern was not the one. Jacking up the entry bribes tenfold would be a correct answer
or replace to new case/grip?
