Re: Tracking Radiation from Fukushima (none / 0)

BS, sheer propaganda. I see no need to refute it, since it makes no quantifiable statements.

How many atoms total? What units are health risks measured in, and what rank does this attain, compared to radon, cigarettes, car crashes, pollution from fossil fuel electricity, etc etc etc.

It all sounds so scary until you think about it like a serious scientist.

Re: Tracking Radiation from Fukushima (none / 0)

I would think that 6000 atoms per square meter is quantitative. Now more information is wellcome, but since it was not an article for general public consumption, there is no reason for the original article to deal with the rest of the data you ask, and I dont't expect gmoke to be in a position to give them.

Re: Tracking Radiation from Fukushima (none / 0)

To boot, the unquantified statements without explicit comparisons come up in a context that is the opposite than what ormondotvos appears to have sensed when speaking of propaganda and scaremongering: they say "at these levels, it is unlikely that this is going to cause measurable health consequences" and what was found "should be reduced by river and stream dilution" (not mentioning that local accumulation is also a possibility).

The key points of the story are: short-halflife Iodine-131 can be used as a marker for the spread of Fukushima fallout globally (it decays so fast that even Chernobyl or nuclear test Iodine-131 is undetectable, not to mention natural sources); and the fallout also included longer-halflife Iodine-129, which accumulated after the previous fallouts. But to me there is little that is new in this, other than the quantification for one given spot.

Re: Tracking Radiation from Fukushima (3.67 / 3)

Incidentally, I just read a related news.

Back in 2007, I wrote about the first major study by Germany's Federal Office for Radiation Protection establishing a statistically significant link between nuclear plant locations and child cancer rates. At the time, the study-makers were perplexed that a health effect arose at general radiation levels orders of magnitudes below where one would expect it.

Now there is a suggestion that the phenomenon might be related to transient events: the escape of radioactive isotopes (in particular Iodine-131, but also noble gases) in gaseous state during the refuelling of the reactors. But data for analysis is hard to come by: the linked taz article (in German) mentions a request to the controlling ministry for half-hourly radiation measurements at one plant, but they only got data with quartal(!) resolution.

In what way is that a reaction to anything I said, or a justification of anything you said?

Scary (none / 0)

I do not understand why mentioning the presence of radioactive compounds from Fukushima is ipso facto scary. Wasn't trying to scare anyone. Wasn't scared myself by the information. I find it interesting that these remnants of the latest nuclear accident are detectable in the Eastern USA and that scientists are studying them.

Sorry if I scared you. The sources are referenced in the piece if you want to check my interpretation.

The new gamma camera may be useful. Hope that doesn't scare you as well.

How do you define "our nature"? Lots of wiggle room there. In all probability, culture is already aligned with "our nature" as we were the ones who built it.

Re: Tracking Radiation from Fukushima (none / 0)

As more reactors fail, or if there's another disruption at Fukushima (say, an earthquake that causes a containment vessel failure), more monitoring will be needed. Up to now, probably not a big deal.

Not sure if this has been mentioned before, but the Skapa Flow, north of Scotland, was the site of a mass sinking of WW1 German ships. Most of them were salvaged, but there's still a business in recovering steel bits from them for the purpose of constructing scientific instruments where steel is required that does not have radioactivity from the atomic bomb era. All modern steel (and everything else) is radioactive.

6000 atoms doesn't sound like many to me...

Re: Tracking Radiation from Fukushima (none / 0)

Fascinating

Certain techniques and devices require very low radiation materials. Geiger counters, medical applications (Whole body counting and Lung counters) and physics applications (photonics) frequently require an extremely low radiation environment, called a Low background counting chamber. A low background counting chamber is a room built with extremely heavy radiation shielding made from low-background steel.
Naval vessels constructed prior to the Cold War are a primary source of low-background steel. Chief among these are reserve fleets and the German fleet scuttled at Scapa Flow.
World anthropogenic background radiation levels peaked at 0.15 mSv in 1963, the year that the Partial Nuclear Test Ban Treaty was enacted. Since then, anthropogenic background radiation has decreased exponentially to 0.005 mSv per year.

Re: Tracking Radiation from Fukushima (none / 1)

Bomb fission has an extermely hard (fast) neutron spectrum, so relatively few long lived isotopes are formed. Thus the steep dropoff. in another ca 350 years, almost all of the decay chains will have run to completion, and the only readily detectable isotope will be technetium.
The fact that we deploy soft spectrum fission in power generation is kind of daft - The very long term toxicity of nuclear waste is wholly a product of the fact that most reactors use thermalized neutrons.

Yet another argument for fast reactors, breeder or not, I suppose?

Re: Tracking Radiation from Fukushima (none / 0)

Except the western nuclear industry seems to operate with a scavenger mentality. They will fight to the death to keep their old reactors running until they break down, try to sell the exact same thing with additional ribbons but have mostly given up on long term development.
