Radioactive Cesium Accumulation in Pacific Organisms Now Going Main Stream

A Marine Food Web Bioaccumulation model for Cesium 137 in the Pacific Northwest
The model outcomes showed that 137Cs can be expected to bioaccumulate gradually over time in the food web as demonstrated through the use of the slope of the trophic magnification factor (TMF) for 137Cs, which was significantly higher than one (TMF > 1.0; p < 0.0001), ranging from 5.0 at 365 days of simulation to 30 at 10,950 days. From 1 year to 30 years of simulation, the 137Cs activities predicted in the male killer whale were 6.0 to 182 times 137Cs activities in its major prey (Chinook salmon, Oncorhynchus tshawytscha). Bioaccumulation of 137Cs was characterized by slow uptake and elimination rates in upper trophic level organisms and dominance of dietary consumption in the uptake of 137CS. This modeling work showed that in addition to the ocean dilution of 137Cs, a magnification of this radionuclide takes place in the marine food web over time.


  1. Bioaccumulation of Fukushima Cs137 is far less than Bioaccumulation of Cs137 from U238 in oceans that undergo nat spontaneous fission. Excel spreadsheet calc will show this. Chop choo.

    1. Thats stupid, 1 1 Bq/M3 CS137 that was in the ocean before was from open air nuke testing. The amount of natural CS137 is much lower than that

      Now they are measuring 8 to 15.

      Why would you even try to sell such an easily debunked lie as that, and I mean HERE.

  2. Easily debunked? Do the spreadsheet then get back to me. Cs137 levels from Fukushima shown no adverse impact. Any thing else is prevarication. End of story.

    1. I already gave you the debunk, CS137 was not in ocean in any significant quantities, and what was there before, around 1 Bq/M3 was from fallout.


      I high school student could follow that logic as a "proof"
