続き2:それを補うため、どうしても目視確認が必要なんだ。だから重いタングステンベストを着た作業員が交代で構台に上がり遠隔操作のオペレーターと連絡を取り合いながら作業する。構台に上がった作業員は相当な被曝するんだ。ちょっとあの日の事をオイラなりに振り返ってみたいと思う。

Feb. 9, 2013 tweet by @Happy11311 translated by EXSKF:
In order to compliment the remote work, visual inspection is necessary. So, workers wearing heavy tungsten vests take turns to go up on the platform, and communicate with the remote control operators to carry out the work. Workers who go up on the platform are exposed to significant amount of radiation. [...]
Tweet translated by Fukushima Diary:
To support camera, we absolutely need visual observation. Human workers with heavy tungsten vest step up on assembly base by turns. They communicate with remote controlling operators. Those workers are severely exposed on the assembly base.

Tungsten is used to reflect neutrons. The use of Tungsten vests suggests ongoing criticality at unit 3.

tungsten is 1.8 times a dense a lead, therefore less bulky for the same radiation protection.
dense material is used to protect against gamma radiation. neutrons will just pass thru it. you need dense plastic or water to absorb neutrons

Tungsten carbide is not tungsten.
Just as sodium chloride is not sodium

Thanks for the info. Honest mistake. Though Tungsten carbide is not pure Tungsten, in my circles it is often referred to as simply Tungsten, So the connection I made when reading this headline was – Tungsten = neutron reflective. I will be more careful next time….

Sorry, i didn't mean for it to sound like a rebuke. I should have phrased it better. Someone needs to invent a "manners check" for the google toolbar.
These poor guys–dead men walking all– sure, they have a shield on their chest, what about their heads? I guess radiation doesn't affect brains.

" I guess radiation doesn't affect brains." Or testicles.

maybe they also have tungsten undies, and the brain? well, who needs one?
Report Comment
I guess they figure "radiation on the brain" isn't such a bad thing for people willing to work for a vcrap company for crap pay at a place rapidly becoming known as the worst workplace environment on Earth and no need for "shielding undies" since they're either cukoo-crazy and/or have "balls of steel" and TEPCO isn't concerned about radiological "neutering" that would reduce the gene pool of those who recruited and transported by industry-associated criminals and then picked up and delivered to wherever they transport their corpses to after they've been "liquidated"?!!~A person doesn't have to be near Fukushima or even have to be in Japan for a mega-nuke emergency many say was/is an ELE to have the event cause their mental health to deteriorate! It's not even necessarily just the radiation detected that could "short-circuit" the brain!~How about the issue/event exposing the industries,govt.'s and so-called "protective agencies" corruption and total lack of concern for the public after trusting them and assuming no expense had been spared to prevent ANY irreversible release events many assumed TPTB would "do the right thing" for the public instead of protecting disgusting,harmful companies/profits who are allowed to continue using technologies far too toxic and costly to justify even their existence much less building more of them!!(?) I wonder if the tungsten vests were anything more than the same "false comfort" the x-ray vests were on the roof…

….not that it matters though as both pure Tungsten and Tungsten carbide are used to reflect neutrons, and I would suggest that is one reason for its use at unit 3. It's a real mess in there.

The stories are all the same…only the dates, quantities and names change. The liquidators will be liquidated.

TEPCO has released photos of the fuel handling mast that fell into SFP3, as the crane was removing debris. http://enformable.com/2013/02/tepco-workers-find-fuel-handling-mast-atop-spent-fuel-storage-racks-in-fukushima-daiichi-unit-3/
The fuel handling mast is now lying lengthwise across spent fuel racks in the pool.
Report Comment
SFP3 has so much debris on top of the spent fuel racks that none of the handles can be seen in the new photos, that I can spot amid the rubble. In uranium fuel assemblies, the handles extend above the top of the fuel racks, as can be seen in this photo of SFP4.
http://www.ens-newswire.com/ens/may2011/2011-05-25-092.html
We have already seen that a great amount of damage to fuel assemblies and fuel racks occurred from falling debris at SFP4.
http://enformable.com/2011/11/video-of-reactor-4-spent-fuel-pool-shows-potential-damage-to-racks/
In the following photo of SFP4, a rack of MOX fuel in the center of the picture shows that MOX fuel assemblies extend even further above the protection of the fuel racks than uranium fuel assembly handles.

We can expect many of the spent fuel assemblies in SFP3 to be heavily damaged when the last of the debris have been removed from the pool. Before SFP3 fuel removal is complete, there may be piles of fuel pellets scattered all over the floor of the pool, sparking constant criticalities, and making those tungsten vests useless.

Simplyinfo.org reports the price of the vests: $8,000 US dollars. I doubt they have very many.
I seriously doubt these vests provide protection for human bodies. More psychological effects than anything else: "Look Hiroshito…this Ultraman vest makes smile as I frolic above the spewing MOX emissions!"
About as worthless as the clunky makeshift lead sandwich-signs used at Chernobyl.
Radiation doesn't need to strike a heart blow. And inhalation radiation poisoning is even harder to prevent. These workers are The Expendables.
