Jiji: 5 billion becquerels of beta radiation in 10 liters of decontaminated water — Includes strontium and cesium

Published: January 10th, 2012 at 2:39 pm ET


10L of water leakage “500,000Bq/cm3″, Fukushima Diary, Jan. 10, 2012:

  • Water leaking from the tank to storage abandoned salty water after purifying system of highly contaminated water
  • It was 10 L[iters] to leak
  • It’s supposed to contained a portion of radionuclides such as Cesium or Strontium, which is 500,000 Bq/cm3

Conversion: 500,000 Bq/cm3 = 500,000 Bq/ml = 500,000,000 Bq/liter = 5,000,000,000 Bq in 10 liters of water

The water it leaks from the waste brine tank, looseness of = volt/bolt – the Fukushima 1st nuclear plant, Jiji, January 10, 2012:

Tokyo Electric Power Company announced that on the 10th, from the waste brine storage tank after the high density contaminated water processing, the water approximately 10 liters which include the radioactive substance leaked. […]

Other than the minute radioactive cesium, the radioactive substance which produces beta ray of strontium 90 and the like per 1 cubic centimeters 500,000 Becquerel was included in the water which leaked.

    Unbelievable how much Bq there can be in one cubic centimeter.
    This equals Bq in 10l.
    But who believes it was exactly 10liters…

  • Radio Radio

    and remember you shouldn’t anything with more than 500Bq in one kg.
    Government official Yasuhiro Sonoda, try drink this water!

      hi radio
      if you look at the video closely the bottle was swapped for one smaller and with no sticker on. he didnt actually drink that water!

    and how is this termed DE contaminated ffs

    I really wonder how they calculate leakage considering that water evaporates. Maybe people have already covered that in here and I could find it if I spent more time up in the tabs at the top of the blog.

    Oh, they probably left off a bunch of zeros as usual… Probably 10,000 Liters or more …

  • How do they ‘decontaminate’ this water anyway? It sounds like they just take out a couple of things, possibly concentrate other toxins into smaller water volume and then call it done.

    What are they left with?

    How much radiation is left over total, per container?

    I am sure they have all of this information, but as usual, they are not releasing any of it.

    I notice that at FUKU they are building HUGE numbers of HUGE water storage vessels. What are they for?

    Then they have all of these smaller square plastic looking ones inside of a basin. What are they for?

      Reverse Osmosis type systems–they tryed several..think only one worked–kind of. Other two or three types didnt work.What they end up with all efforts..concentrated Highly radioactive “brine” and filters also highly contaminated. The brine or concerate is a killer..the filters as well. By the way, the vents for the stacks.also have filters..but likely are not used as we see a lot of plumes which you could not see if filtered to keep 98% of radiation from air. So HUGE water storage..and dangerous. Oh..couple workers got sick there..didnt they?? Heart or cardio event? Some young some old? Does anyone have a plan about what to do to keep radiation out of air and sea? Right now..looks like the little Dutch boy standing with a finger in the hole in the dyke-does anyone have a clue what to do next?

        Are you sure it is just Reverse Osmosis (RO)? RO should only be a pre-treatment for removing ionic radionuclides. Ion Exchange first in dual beds, then followed by mixed bed polishers would remove most from the water. A problem with ion exchange is that the resin will become radioactive. However, the volume will be greatly reduced and the radioactive material greatly concentrated.

        My guess is that because of the huge expense of properly disposing of radioactive resin is that they are choosing to just dilute it into the sea for financial reasons.

        Most of the non-noble radionuclide ions can be removed from the resin by adding acid and caustic washes depending on the resin. The washes will be smaller in volume (small percentage) and the radionuclides recovered through several methods with increasing costly safety precautions necessary.

        The water also needs to have many stages of treatment because as the noble radionuclides decay, they will produce other radionuclides. Some radionuclides such as the isotopes of oxygen do not last long and just a few days of storage is adaquate for transition of a significant portion.

        One pass of RO may just be window dressing.

    RW Via @sciam Scientists say Fukushima helped advance Doomsday Clock to “five minutes before midnight” http://t.co/zpgL4HHY
    5 minutes ago

    I disagree with the wording.
    The Nuclear Industry helped advance the Doomsday Clock to 2 minutes before Midnight.

    hey brainiacs

    100.000cm3=100.000 x 500.000=

    who call it longer “water”?
    thats a fckng liquid atombomb!!!

  • nuckelchen nuckelchen

    ups i’m wrong!
    but its egal,
    its trotzdem liquid atombombium
