It seems to stand the test of reason that the radionuclides
deposited
from Fukushima were not deposited upon land, they were deposited
into the
Pacific Sea upon moving seawater along with wreckage which was
drawn out to
sea from the Tsunami. This was in addition to direct injections of
highly
radioactive water that was dumped from Fukushima directly into the
sea.
All of that contaminated wreckage along with the vast amounts
of
radioactive seawater have been and are heading directly to
the
US West Coast. Every wind current and Pacific Sea current
indicates
that is true.
While the radionuclides move here, they are constantly being fed
into
the natural water cycle.
Your following quote illustrates why this is important and ongoing:
"(1) The amount of fallout in the soil will depend strongly on how much rain the area received in late March and early April, when the air concentrations were at their highest. Said in another way, "wet deposition" (rain) is much more important than "dry deposition" (particles settling out of the air)."
Given these radionuclides are now mixed into the water cycle,
'Wet
Deposition' is still happening- there is just 'little to no
monitoring' going on. The monitoring that is happening is
fairly
insufficient as we need full Gamma, Beta as well as Alpha
testing
to get a full picture. We also need additional ranges of
testing.
'Lichens' (at high altitudes for example), possess unique
filtering
ability which could be useful:
The manner in which the EPA went about testing (air canister/air
filter
testing) for Plutonium was about the best way to test for
Plutonium, if the
goal was 'not' to detect Plutonium. Other methods of testing, such
as Soil
samples from under raingutter downspouts as well as lichens at
higher
altitudes are likely to easily reveal radionuclides with decay
rates as far
reaching as Plutonium.
