Tracking Radiation from Fukushima

Scientists Track Radioactive Iodine in New Hampshire from Japan Nuclear Reactor Meltdown

Testing in New Hampshire's Mink Brook watershed during March through May 2011 resulted in calculating radioactive iodine deposition in the soil at a total amount around 6,000 atoms per square meter. Dartmouth research associate Joshua Landis commented that "at these levels, it is unlikely that this is going to cause measurable health consequences."  The amount in stream sediments was double the amount in soil but should be reduced by river and stream dilution.

This radioactive waste from Fukushima consists of iodine-131, "highly radioactive, acutely toxic" with a half-life of about 8 days, and iodine-29, less radioactive but with a half-life of 15.7 million years.  "Due to its long half-life and continued release from ongoing nuclear energy production, [iodine-129] is perpetually accumulating in the environment and poses a growing radiological risk," the authors of the Proceedings of the National Academy of Sciences report point out.  A nuclear reactor produces 3 parts iodine-131 to one part iodine-129.  "Once the iodine-131 decays, you lose your ability to track the migration of either isotope."

gmoke :: Tracking Radiation from Fukushima


The Japan Aerospace Exploration Agency (JAXA) has created a prototype "Super-wide Angle Compton Camera" capable of creating images of gamma ray-emitting radioactive particles. This equipment is based on the gamma ray-observing sensor technology to be added to the next X-ray observation satellite, ASTRO-H. It is expected to be able to create visual images of radioactive particles that have collected at high altitudes such as building roofs where it is difficult to conduct measurements with existing survey meters. Taking advantage of its wide vision (180-degree) capability as well as its ability to distinguish gamma rays from nuclides, it can create images of Cesium 137 (Cs-137) and Cesium 134 (Cs-134) that have widely dispersed on the ground and residential houses. (Attachment-1)

On February 11, 2012, JAXA, Japan Atomic Energy Agency (JAEA) and Tokyo Electric Power Company (TEPCO) conducted a field test of the dose measurement and imaging survey using the "Super-wide Angle Compton Camera" at Kusano area of Iitate village in Fukushima Prefecture. The results yielded the successful image capturing of the dispersed radio-cesium over a much broader area and to a higher degree of accuracy in comparison with existing gamma cameras. (Attachment-2)

We need a zero emissions society and culture, especially where such long-lived pollutants are concerned.

More radiation monitoring?
not yes
not no
neither yes nor no
both yes and no
don't understand the question?
none of the above

WOW - what a shitty post GMOKE ... you should write for the Daily Kos (0.00 / 0)
NOW here is what Gmoke DOESN't tell you about Iodine 131 and Iodine 129 ... IT IS ALL AROUND YOU AND HAS ALWAYS BEEN AROUND YOU!  We walk around barefoot on Iodine 131 and Iodine 129 in the summer time.  Doctors give people with a thyroid condition Iodine 131 to keep them alive.  In other words PEOPLE WITH A THYROID CONDITION EAT IODINE 131.  And IODINE 131's cousin ... Iodine 129 (the one with the big bad scary half-life of 15.7 million years (eeew scary # BTW Gmoke) is "less radioactive" than the Iodine 131 THAT PEOPLE EAT.    

Iodine 131 and Iodine 129 would have been found in New Hampshire even if Fukushima were never built.  In the 1950's and 1960's the worlds superpowers were firing off nukes on test grounds around the world ... this material has settled all over the world and people have been in contact with I-131 and I-129 FOR THE PAST 60 YEARS!

What would you think if Gmoke came in here screaming . . .

OMG GUYS! OMG! OMG! We found I-129 in the ground left over from the Nuke Testing of the 1950's and 1960's OMG! OMG! .... Would you shit your pants like Gmoke did?  Probably not.  

This is just another example of people that don't have a clue (Gmoke) who pretend to know what they are talking about yet under scrutiny fall apart after 5 minutes of googling.  => http://www.epa.gov/radiation/r...

Radiation Monitoring (5.00 / 1)
All I am suggesting is that we should monitor radioactive materials, especially long-lived radionuclides wherever they come from because they can accumulate in the environment and concentrate up the food chain.  If you don't want radiation monitoring because you think ALL radiation is good for you, OK. You have a right to your own opinion.

Personally, I think we need a strict zero emissions policy for everything we produce.  Zero emissions as a goal the way TQM and Six Sigma use zero defects and "3.4 defects per million opportunities" as a measure of quality.  I'd like to see dramatic growth in the quality of our society and culture based upon these ideas within ecological systems design leading to a restorative economy rather than one that makes, predominantly, garbage.

Radon, medical, and commercial use and waste are probably the ways most people are exposed to radionuclides (along with combustion by-products of fossil fuels).  Radiation monitoring systems would help us reduce those exposures as well.

Just passing on some interesting information I thought.  Never pretended to know what I'm talking about but did give my references and believe my words do not misrepresent the NH researchers (the gamma camera piece is verbatim from a press release by those notorious anti-nukers TEPCO or Tokyo Electric Power, the owners of the Fukushima nuclear power plants).  My shorts are unshat, thanks for your worries about my digestive system, and I ain't screaming.  From my perspective, you are.

prime target for a deleted post... (0.00 / 0)
but since gmoke responded so thoughtfully, I'll leave it as is. That said, consider this your second warning for violating our posting policy. Third time will be more of a goodbye.

Just stating the obvious . . . that Iodine 131 and Iodine 129 has been in New Hampshire (actually everywhere on the planet) since the 1950's (0.00 / 0)
If gmoke mentioned this fact he wouldn't get the same level of attention he would get if he hid that info.  

He basically took a 60+ year old problem and slapped the Fukushima name on it and tried to pass it off as reason to say this . . .

Personally, I think we need a strict zero emissions policy for everything we produce.

That is F-ing crazy talk, we don't have the technology or the capabilities for a zero emissions society.  It's just plain crazy to even consider with today's technology.

pssssst - hey gmoke ... there is mercury in CFL light bulbs ... (0.00 / 0)

Hey, Ram Rod Radio (0.00 / 0)
There are mercury switches, with probably a lot more mercury, in those kiddie sneakers with little lights that flash on and off when the kiddie takes a step.

I am in favor of a zero emissions standard for everything, a Six Sigma environmental culture, including mercury.

I sorta kinda doubt that you care all that much about heavy metal pollution or any kind of hazardous waste unless it helps you make a cheap rhetorical point.  Then again, I could be mistaken.

gmoke - this is sincere.. . (0.00 / 0)
You're right, I was making a cheap rhetorical point, and I hate it when people pull that move on me.  So I take it back.

I definitely made a crap argument above, and you're right to call me out on it.
