The Bioaccumulation of contamination in plankton, US Armed Forces, 1955

Quote (emphasis added) “Page 59. The problem of radioactive particles falling into the ocean raises the question of their availability to this portion of the biosphere. Plankton normally found in sea water are consumed in large quantities by fish.

These plankton concentrate mineral elements from the water, and it has been found that radioactivity may be concentrated (Page 60) in this manner by as much as a thousand fold. Thus, for example, one gram of plankton could contain a thousand times as much radioactivity as a gram of water adjacent to it. The radioactivity from these plankton which form a portion of fish diet tends to concentrate in the liver of the fish, and, if sufficiently high levels of contamination are encountered, could have a marked effect upon the ecology of an ocean area.

Concentration factors for Cs-137 in marine algae from Japanese coastal waters.

Concentration factors (CF: in wet algae/ in filtered seawater) for Cs-137 in Japanese coastal algae, were investigated during 1984-1990. Cs-137/Cs(stable) atom ratios were also examined to clarify the distribution equilibrium of Cs-137 in marine algae and sea water. The CFs in marine algae were within the range of 5.4 approximately 92, and the geometric mean of CF was 28 +/- 2 (standard error) in Japanese coastal species. The CFs in edible species were within the range of 5.4 approximately 67, and the geometric mean of CF was 26 +/- 4 (standard error). The values of Cs-137/Cs atom ratios in marine algae and sea water indicated that Cs-137 reached an equilibrium state in partition between algae and sea water. Therefore, the CF value obtained in the present study can be regarded as an equilibrated value. Our results showed that the CF for Cs-137 in Japanese coastal algae were consistent with the Japanese guideline CFs, but were smaller than the recommended value by IAEA.

Greenpeace today announced that its flagship, the Rainbow Warrior, has departed Taiwan for Japan to conduct contamination tests on seawater and marine life in the area surrounding the stricken Fukushima Daiichi nuclear plant.
“Japan relies heavily on the ocean to feed itself, and given the continual leaking of radioactive water into the marine environment – including TEPCO’s release of huge quantities of contaminated water (1) – it is critical that independent testing is undertaken, in order to assess the true extent of the contamination and the possible impacts on public health and the food web,” said Junichi Sato, Greenpeace Japan Executive Director.
“We have informed Japan’s government and are currently working through the appropriate channels to ensure we can add marine research to the radiation monitoring already carried by our land-based teams in the Fukushima area (2)”, said Sato. “Tens of thousands of people remain at risk from the radiation released by the Fukushima Daiichi nuclear plant – we wish to continue providing independent data and assessments that will help people in the Fukushima area make the right decisions to protect their lives and livelihoods”.

The Japanese government subsequently banned the Greenpeace mission.

    Outstanding information, but it could be a little bit more in depth.
    Not whining, but I hate going from blog to blog to blog simply to discover a
    couple of solutions; why can’t 1 site simply have them all for once! I’m
    sorry, I’m rambling and worn out…. I tend to get irritable and I’m taking it out on your site.

    My bad.

      When Devin is tired, she’s too lazy to download the entire text and read it all up. And then, she has to find all
      the modern stuff that attempts to deny the early stuff, figure out from that what is true and what is bullshit,
      (not that all the old stuff was true anyway (who knows, plankton probably concentrates fallout by zillion x rather than
      10,000 times) and then come to conclusion that seeing as governments do not accept that internal emitters are a hazard many
      times worse than external dosimetry indicates, and then decide whether to be pro or anti nuke, because its easier not
      to care anyway, but even when she’s tired she’s trying to figure it out.

      And that’s good Devin, not bad.
