Plutonium detected in soil at Fukushima nuke plant
TOKYO, March 29, Kyodo
Plutonium has been detected in soil at five locations at the crippled Fukushima Daiichi nuclear power plant, Tokyo Electric Power Co. said Monday.
The operator of the nuclear complex said that the plutonium is believed to have been discharged from nuclear fuel at the plant, which was damaged by the devastating March 11 earthquake and tsunami.
While noting that the concentration level does not pose a risk to human health, the utility firm said it will strengthen monitoring on the environment in and around the nuclear plant.
Meanwhile, high levels of radiation exceeding 1,000 millisieverts per hour have been detected in water in a trench outside the No. 2 reactor's building at the nuclear plant, with the contaminated water suspected to have come from the reactor's core, where fuel rods have partially melted, authorities said Monday.

Nuclear accident bad. Plutonium not bad?????
I keep getting this unnerved perception that nobody is trained any more on how to assess nuclear engineering operations, and quite frankly, it’s annoying, because I know they exist.
Btw- now 1000x higher at & around site.
This is exactly what happens when they won’t let anyone safely contain nuke waste deep underground in a secure facility and re-process it and they have to “store” it onsite.
Instead you have an accident at a nuke power plant and it makes it 100X worse than it could have been.
Most of the spewing from the Fukashima plants has been from spent fuel.
Yeh...Just like xrays were good for us....which is why the tech stays behind a lead wall AND we NOW have to wear a gym mat for simple mouth xrays. Is our mouth near our brain???
. . unless your in politics, . . . owwwwwww!
Don't worry, 24,000 years will be over before you know it.
I think you could find quite a few respectable scientists who would say that the only safe level of plutonium is zero. Beyond that, it’s all a matter of luck.
“Ann “Corponaziwhore” told us it’s good for us!”
That’s not what she said. If you’re gonna accept what the libs cherrypicked,,,, And she tweaks their noses with outrageous statements all the time! Usually said with a smirk on her face. Read her actual article, and the facts nd studies she sights;
I’m no big fan, but,,,,,,,
All you need to see on that is the PU238, 239 and 240
btw , notice the dates of that test. It is days old and they just now revealed the info.
Then, I need to see the same tables for Cesium-137 (we can ignore Iodine-131 due to its short halflife).
Two tables, please, for each of the 6 reactors. Some of the reactors, I'm told, did not use PU as a fuel, and obviously the values for PU for these will be zero.
Sheesh, such a response to an obvious (if cheap) gag...
How do you know that?
What a coincidence.
Who would have figured that they would have built a nuke plant on top of a plutonium deposit?
Things to NB:
1. The amount released into the environment during nuke weapons testing:
"Atmospheric testing of nuclear weapons, which ceased worldwide by 1980, generated most environmental plutonium. About 10,000 kg were released to the atmosphere during these tests. Average plutonium levels in surface soil from fallout range from about 0.01 to 0.1 picocurie per gram (pCi/g). "
10,000 kg is a lot of Plutonium already spread in the environment.
2. Above-ground weapons tests consisted of either popping off a nuke at ground level (eg, on a tower), or an air drop from a plane, usually retarded by a chute.
In either case, the resulting fallout was more widely distributed because the nuclides resulting from the explosion were pushed into the jet stream by the vertical thermal column resulting from the bomb.
3. The low specific activity of plutonium isotopes, coupled with the alpha emission as the typical activity, means that ingestion of Pu particles is the greatest danger to humans.
OK, so what's the health outcomes of Plutonium ingestion (which is the most severe form of exposure to Pu, since the longest-lived isotopes give off alpha radiation)?
Well, we have 37 Los Almos workers from the Manhattan Project who have been studied:
From Google Docs:
"Manhattan Project Plutonium Workers at Los Alamos," George L. Voelz.
Google the title in quotes, and you should find the doc. I tried to include a URL and ended up with the solid mess of text above, so I removed the URL.
What's the bottom line?
"Data on 26 workers exposed to plutonium-239 in 1944 to 1945 and observed for a period of more than 50 years have consistently shown that the mortality rates for all causes of deaths and for all cancers are not elevated compared with either U.S. white males or unexposed Los Alamos male workers with comparable hire dates. This ﬁnding differs from some popular misperceptions that large health risks occur after any exposure to plutonium. The median effective dose to these men is 1.3 Sv (mean dose = 2.1 Sv). The incidence of speciﬁc cancers, especially lung cancer (4) and osteogenic sarcoma (1), is interesting, but additional data are needed to draw conclusions about the relationship between plutonium doses comparable to those in this study and the induction of excess cancers."
Now, look at the median effective dose to those men: 1.3 Sv. Not "milli," not "micro." Full-on Sieverts of exposure over their lifetimes since Los Almos. That comes from Pu lodged in their tissues from inhalation, ingestion, deposits into the flesh from cuts/wounds, etc.
As I keep telling people: Go do your own homework. There is plenty of data out there. I've read it, and that's why I'm not running in circles, screaming and shouting. The data show that, at the *very* least, that the widely-perceived lethality of radionuclides isn't as high or certain as the popular press would like to portray.
But some of you want to panic about something, so I guess that this is as good as any reason to panic. Go ahead, get it out of your system.
<P>aragraphs are our friends...
Is it really all that complicated to begin each <p>aragraph with an html <p>aragraph tag?
No, but then I’m lazy when posting. I’ve put up a formatted version which works.
Fair enough. I'm lazy when it comes to reading others' posts. Large blocks of text are hard to read, so when I see them, I simply skip on down the page.
Yes, I understand. It was formatted with para’s in the plain text, but some character sequence caused the default posting sw to just jam it together into a solid block.
I don’t ordinarily task people with solid lumps of text.
“This is exactly what happens when they wont let anyone safely contain nuke waste deep underground in a secure facility and re-process it and they have to store it onsite.

You can’t permanently store used fuel rods until they’ve quit producing heat from residual reaction. As best I can tell, this takes several years of temporary storage in cooling pools.
2.) My Japanese is a little less than rudimentary, but it appears that the dates and times are when the samples were taken. If so, the turnaround of a week to do the analysis is not unreasonable.
What is your opinion?
Actually, that's not true.
U-235, which is the "enriched" in "enriched uranium," will split promptly when hit by a neutron, and thus add a bit of heat to the reactor's core.
U-238, on the other hand, which makes up over 90% of the uranium in ordinary nuclear fuel, turns into plutonium when it's hit by a neutron of the proper energy.
This newly-created plutonium can then subsequently be split by another neutron, adding another bit of heat to the nuclear reactor's core. In fact the fission of new plutonium contributes a significant amount of heat to the total produced by the core by the time the fuel is swapped out.
So in other words, every nuclear reactor that's been running for any amount of time has a considerable amount of plutonium in its core, which is created and then "burned up" as the fuel ages.
The trouble is that radiation is so easy to detect. If we could see, smell, and taste all the toxic and alarming contaminants in our water and food, we'd probably all starve to death.
Radiation is everywhere, all the time, and always has been.
When it comes to radiation, folks out there are starting to sound like the "homeopathic medicine" adherents, who try to pass off a bottle of water with a few molecules (if any) of "active" ingredients in it as a "remedy."
As I pointed out on another thread last week, the “fallout” or whatever contamination from Fukushima doesn’t concern me in the least. Really.
But that doesn’t mean that I ignore all risks from radiation. Our house has a radon venting system under the concrete pad. It runs all the time. And, after examining the lung cancer stats on non-smokers who live in houses in states with elevated levels of radon in the soil, it is clear to me that absent a nuke weapon being popped off within two miles of me, the radon risk outweighs all other radioactivity risks in my life.
This has not only NOT been done, these subtopics in the discussion have been uniformly either ignored or distorted by the sensationalist cretins in the alleged "media".
My opinion? My opinion is that anyone who lacks both a degree in nuclear physics or nuclear chemistry and a US Navy certification in nuclear operation should be barred -- by law -- from "journalising" on the subject. Most of the (very few) qualified commentators I've seen/read in the past two weeks are VERY clear in their explanations and VERY deliberate in their comparisons and evaluations.
Well why don’t you ask why Tepco hasn’t release all of that ...
Yes, it is now in the trenches
NEI: UPDATE AS OF 1:30 P.M. EDT, MONDAY, MARCH 28:
Tokyo Electric Power Co. has detected isolated, low concentrations of plutonium in the soil at the Fukushima Daiichi nuclear power station. The density of plutonium is equivalent to the fallout that reached Japan from nuclear weapons testing during the Cold War, the company said.
TEPCO conducted analysis of plutonium contained in the soil collected on March 21 and 22 at five locations at the Fukushima Daiichi plant. Plutonium 238, 239 and 240 were detected, however just two of the samples may be the direct result of the recent incident, considering the ratio of the plutonium isotopes.
“The density detected in the plutonium is equivalent to the density in the soil under normal environmental conditions and therefore poses no major impact on human health,” TEPCO said. The company said it plans to strengthen environmental monitoring inside the station and surrounding areas.
And in the physics forum here is what one poster said
At sampling spots 1 and 5 the ratio of Pu-238 to total Pu activity is of the order of 1..2, which means the Pu originates from fuel with burnups > 10 MWd/kgU, i.e. reactor fuel. So, even though the absolute value of the Pu activity is not significantly higher than that resulting from the atmospheric nuclear testing, its composition implies that some fuel damages have occurred in such a way that small amounts of fuel have been dispersed to the vicinity of the plant.
man found dead
did radiation kill him or did he die from something else and is now too “hot” to remove
5 kilometers from the plant
A research team has detected an increased level of radiation in seaweed and rainwater samples gathered in B.C., and attribute the rise to the crippled Fukushima nuclear complex in Japan.
Nuclear physicist Kris Starosta of Simon Fraser University said As of now, the levels were seeing are not harmful to humans. [W]e have not reached levels of elevated risk [of cancer].
Thanks for that video link. Wonder if those trenches got filled by the Tsunami ? At any rate, it doesn’t matter how thick the concrete is around a nuclear reactor. A chain is unfortunately only as strong as its weakest link.
Officials Alter Removal Plan For Plutonium The Material At Fort Dix Spilled From A Nuclear Warhead In 1960.Since 1960. In 1960 a missile containing a plutonium warhead caught fire. A Fire! Melting! Soil! Air! Plutonium! Less than 50 miles from Manhattan!
Panicked yet? People dying all over? FIFTY ONE YEARS AGO WE HAD A PLUTONIUM INCIDENT -- where's all the dead? Where's a single dead person?
Thanks for the sanity.
The revelation raises more questions about the scandal-tainted past of the Tokyo Electric Power Company (Tepco) and the governments perceived soft regulation of the industry.
The operator of the Fukushima No. 1 plant submitted a report to the countrys nuclear watchdog 10 days before the quake hit on March 11, admitting it had failed to inspect 33 pieces of equipment in its six reactors.
A power board distributing electricity to a reactors temperature control valves was not examined for 11 years, and inspectors faked records, pretending to make thorough inspections when in fact they were only cursory, Tepco said.
It also said that inspections, which are voluntary, did not cover other devices related to cooling systems, including water pump motors and diesel generators.
Plutonium not a problem and everything is A-OK,..is that your story?
Those in Japan surely know by now that TEPCO can’t be trusted. Just a very short time before the earthquake hit they admitted they hadn’t done safety checks on equipment. It is documented they have lied about the safety of their equipment.
Those people in Japan darn well better be worried about what kind and how much Plutonium they might be subjected to when they inhale.
Deadly exposure: Plutonium-related cancers plague children of the Manhattan Project
I have to say I’m extremely suspicious of newbies spewing disingenuous hyperbole.
Hi, how are you? I will be glad when we get some really warm weather that will stick around for more than a day.
Yes! There are idiots posting this anti-Anne stuff. Read her column, and anyone can see that she’s right on the money. And I’m not that big a fan of hers,,,, but I’d like to get my hands on her!
