I didn't see Godzilla in that picture even after reading the caption.. twice. I thought "what does that woman have to do with Godzilla?"

Radioactive Ass, of course I used Bq.   It is the SI standard unit for radiation emissions.   It is the unit that every scientist and expert uses when talking about things like radioactive emissions.   It is the unit that is used in the scientific papers I linked to.   Yes, the numbers gets big.   Especially when you are talking about emissions from three nuclear reactors simultaneously melting down right next to each other in ways humans have never before seen.   The emissions ARE big.   If people want to be willfully ignorant about the units, that is their problem and not the scientific community.   Not everything can be dumbed down and pre-digested for the masses and still have any relevant meaning.

And thanks for sharing your uninformed 'back of the napkin' calculations.   If you look at the first paper I linked, written by scientists and published in a recognized scientific journal, it clearly states that airborne radioactive cesium emissions in the first week were roughly 50% of Chernobyl and the radioactive xenon emissions were twice that of Chernobyl.   And yes, air can be contaminated by gasses and small particles.  Thats why we have things like a pollen count, clean rooms.   This isn't a cherry picked paper, and you can easily find hundreds with similar measurements.   The disasters ARE comparable.   And those numbers don't include the massive amount (greater than atmosphereric, it seems) that is leaking into the ocean.

The big differences between the two, from a human health perspective is that Chernobyl deposited most of the contamination on land.   Fukushima mostly at sea.   Fukushima did manage to contaminate some land as much as Pripyat.   Scary part is, those parts of Japan weren't evacuated and are still active farms (way to go, guys).   Another difference is, we can avoid growing crops near Chernobyl but we can't stop the fish we eat from swimming near Fukushima.   That, and both fish and seaweed tend to bioaccumulate radioactive isotopes.   The health affects here in the US may not be very significant, but I wouldn't say that about the west coast of Japan where people eat sushi and nori.

Ringshadow: Now tell me how it's worse than Chernobyl, that's been sitting there decades after their god damn reactor had a steam-related excursion then caught on farking fire and the fire spread graphite-laden smoke (a carcinogen before it was radioactive) across half the globe.


Someone explained it to me as if you took all of what has been released so far from Fukishima and could somehow magically convert it all into Radium it would fit inside a 2 liter bottle with plenty of room to spare (assuming that about 30 trillion Bq's have been released so far). To put it another way, if you put two dimes in your hand that's about how much radium would have been released every week (by weight, by volume it would be even less than that). That is to say about 5 Curies per week on average.

It's just as disingenuous to describe it that way (2 dimes worth) as it is using 190 billion Bq's per week to make it sound as bad as possible.

Radioactive Ass:

...
I will bow out to someone who clearly understands this process more than I do. I only know it from the "What I have to do deal with these people and get their gear out" stance, being radiation protection and all.

Frankly, I really don't know the scope of the leak. I tend to be cynical about such things given that the reaction to 'contaminated water leak' tends to be extremely overblown by the media, and the fact that the measurement was given in becquerels, which is just an asshole measurement really only used for the ordering of radioactive sources in the industry (same with the curie). Either way, as near as the numbers got crunched in another thread, they seem to have had a tablespoon or two of cesium get loose.

Which don't get me wrong, that sucks because it's a bioaccumulating element as far as I know, but for god's sake. People collect antique radium bottles and fiestaware.

/very cynical of any news from Fukushima due to to the critical levels of BS that surround it

Ringshadow: Freeze dams in piping is pretty common as they make for less chance of a primary leak from failed valve seals, seats, glands, packing and gaskets, but for this they are talking about freezing the earth surrounding the site essentially making a giant tank made out of what's akin to permafrost. The technology has been used before to temporarily stabilize the ground while tunneling under at risk structures. For that they use huge portable refrigeration plants with the coils buried in the ground.

My first question would be what is the temperature of the water when it reaches the "Permafrost" and what would be done to overcome that. Secondly, to what depth are they going to make this wall as there is no way that I can think of to easily make the bottom of the "Tank" so they would have to at least get it down a few feet into a non permeable layer of ground such as clay or rock to form some sort of seal and lastly what are they going to do when the tank eventually overflows or the ground is so saturated with water that it places structures on the ground inside the "Tanks" at risk of foundation failure or liquefaction in the next earthquake. I'm assuming that they will be building sumps to pull contaminated water out of and treat it but that capacity has to be at least about 10% greater than what they are pumping into keep it cool now just to allow for rainfall.

Okay without getting into the fact that Tepco needs to be vigorously slapped back and forth until their next three generations have shaken baby syndrome..

This is ALMOST standard operating procedure. Freezing pipes for repairs where valves are not available to stop the water is done industry-wide, and not just in nuclear power. Pretty much any operation where you're moving a fark-ton of water and you need to do pipe maintenance or replacement and there's no valve convenient, you'll find freeze dams.

And oh my god are they a pain in the ass. Liquid nitrogen is the common method and dealing with that shiat requires a small fleet of people. When the bottles go on the elevator, no one can ride with them, so they have to have people on each floor blocking the elevator until the bottles get to their destination and are removed. The freeze seals have crews actively with the gear 24/7, which is a damn flying spagetti monster's worth of cabling across the area to wherever the lowest dose location is for these people to lurk.

And THEN all of that stuff has to come back out of the radiologically controlled area! So senior techs have to either shove it in a small article monitor but more often than not, this shiat has to be hand-frisked, hand wiped and the bottles WILL vent in your face if they get a chance to.

/saw that happen to a guy who was moving one of the bottles
//lucky for him he had his safety glasses on
///he had icicles in his mustache

Jeez, same here. Except I was thinking, "day-um she has some nice teeters".
