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.

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.
ReplyDeleteThats 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
DeleteNow they are measuring 8 to 15.
Why would you even try to sell such an easily debunked lie as that, and I mean HERE.
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.
ReplyDeleteI 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.
DeleteSheesh
I high school student could follow that logic as a "proof"
