@sims "The study found cesium-137 at levels between about 590,000 and 2.19 million becquerels per cubic meter." from www.asahi.com although I don't have the original data - I think Ralph Unger may have just posted where the numbers werte pulled from

And the limit for consumption and planting is 500 bq/kg, that is my point I dunno! :-)
by Ralph Unger 4/10/2011 12:34:30 PM

@DonnerT, Wasn't this the reason why they conducted the experiment at Chernobyl that went so horrible wrong ? Afaik they were trying to see if the inertia of the turbines could keep the electrical generators running, until the diesels generators had time to kick in (SCRAM situation).

I say 1700 to 1 but even in this forum I have people questioning my numbers, as they should.
by Ralph Unger 4/10/2011 12:36:19 PM

That is about a 3 ft X 3ft X 3ft cube vs 1 kilogram of soil.
by Ralph Unger 4/10/2011 12:38:35 PM

Yeah, 1.7t / m3 sounds the right order of magnitude.. think there must be some kind of logic behind when they use Bq/m3 vs. Bq/kg though.. or is Bq/kg mainly for food? So it's something like if you grow rice on 5000 Bq/m3 soil, you get 500 Bq/kg rice?

*disclaimer* Numbers are just an example and may in no way reflect reality
by sims 4/10/2011 12:39:31 PM

Now I have look ed at the numbers and AI cannot say that is true. lol.
by Ralph Unger 4/10/2011 12:40:33 PM

I have to conclude, they are trying to confuse everyone

@DonnerT I've seen cut away pics of a submarine that had the battery capacity needed to provide backup power - huge banks.

If ya can't dazzle them with brilliance...
by Ralph Unger 4/10/2011 12:43:14 PM

quoting any of these numbers is a bit meaningless without stating how deep the contamination goes anyhow.. I'd be far more worried if they had a lot of Bq/m3 going 50cm deep than if it was a 1mm layer at the top.
by sims 4/10/2011 12:44:14 PM

@sims I was just thinking about whether they were doing surface scrapings versus core samples. If you're going to quote it per cubic meter, are you doing it because the contamination goes deep, or are you doing it to try and hide the fact that the contamination at the surface is incredibly scary-high?

mext have updated the readings you are discussing www.mext.go.jp
by elainekirk 4/10/2011 12:47:28 PM

www.mext.go.jp I dunno about this sampling , but some others mentions depth.

@WolfDK Don't know that much about Chernobyl. I've always wondered why they couldn't use the 7% to 10% thermal power remaining after SCRAM to run the turbines enough to maintain cooling circulation. Maybe the loop integrity was lost in the quake. The game was over when they lost generator backup. Since then it has been the show steer, the curious monkey and the corm cob. (30yrs not 39)

I am Sharkman in the TOD forum. Lots of good info to be had there. This is their current thread. www.theoildrum.com

@George Gibb But submarine nukes are much smaller and even then they have like only an hour or hour and half to get the reactions restarted.

Only going critical could do that in my book.
by Ralph Unger 4/10/2011 12:59:18 PM

@DonnerT I was thinking more along the lines of the diesel powered subs, it was something like 1/6 th of the inside volume was devoted to battery space.
by George Gibb 4/10/2011 1:00:08 PM

When researchers wanted to make ball lightning. They used nuke sub batteries. Those things got a lot of juice!

Gotta go now if I'm gonn make it to church on time.

Pray for the "jumpers" at Fukushima, I will.

A bit old, but still interesting in the face of a lack of new developments in Fukushima: www.ucsusa.org

@Ralph Unger I do that daily. The unsung heros!
by DonnerT 4/10/2011 1:06:51 PM

@Wold DK and anyone else interested....Chernobyl[Most Likely] went like this....They were conducting an expeiment to see if they lost offsite power and all BACK-UP's could they restart the reaction to produce power to run the cooling system, when they strated radio Xenon(Neutron Killer) built up and killed the reaction, the two operators paniced, the water drum operator pumped in more water to raise pressur to try and drive turbines, the rod operator lifted control rods at an alrming rate, beyond design specs, as the reactor kicked in again the pressure spiked and pushed all the water from the steam drum into the reactor causing a violent spike in reaction, SCRAM activated but in RBMK's it's like 15 second process, by the time the control rods started inserting the pressure was too high and they got stuck...too late lid blew and the rest is history! abstract by me from the documentry Seconds from Disaster(sorry for the big post!)

It's like the BP mistake, good men die because of bad decisions from corporate bosses.
by Ralph Unger 4/10/2011 1:08:16 PM

BP had it's safest year ever!Even including that small Gulf of Mexico thingie.
by Ralph Unger 4/10/2011 1:09:50 PM

It was Trasnocean, but the same bonus applied I am sure.

Have we seen these photos? These two combo photos released Saturday, April 9, 2011 by Tokyo Electric Power Co. via Kyodo News show before (top) and after (bottom) the March 11, 2011 tsunami triggered by a strong earthquake hitting the compound of the Fukushima Dai-ni nuclear power plant in Futaba town, Fukushima Prefecture, northeastern Japan.
