(4) The amounts of Pu isotopes released from the
FDNPP accident
Unlike the intensive studies on the estimation of total
amounts of fission products, such as 131I and 137Cs, very
few studies have addressed the estimation of total amounts
of Pu isotopes released from the FDNPP accident, due
partly to the lack of environmental monitoring data.
Zheng et al. made a rough estimation of the atmospheric
release of Pu isotopes based on the 137Cs/239+240Pu activity
ratio observed in forest litter samples in the 2030 km
zones relative to the total amount of 137Cs released
estimated by METI and Stohl et al., with an assumption
that 137Cs and Pu siotopes followed the same deposition
mechanism, and no significant variation of the
137Cs/239+240Pu activity ratio during the release and
deposition. As shown in Table 1, the total amounts of
released 239+240Pu and 241Pu were 1.0×10^9
2.4×10^9 Bq, and 1.1×10^11
2.6×10^11 Bq, respectively. These values are
very close to those estimated by METI, and about 4
orders of magnitude lower than those of the Chernobyl
accident.
It was found that although the inventories of Pu isotopes
in the reactors in the Fukushima DNPP were ca. 3.5 times
higher than those in the Chernobyl Unit 4 reactor, the
percentages of core inventory released for both 239+240Pu
(13×10^-5 %) and 241Pu (24×10^-5 %) were about 5 orders
of magnitude lower than those of the Chernobyl accident.
This estimation is in a good agreement with that of
Grambow and Poinssot. However, Schwantes et al.
reported an estimation that roughly 2×10^-3 % of the total
plutonium inventory from Units 1 and 3 was released into
the environment, which is two orders of magnitude higher
than those of Zheng et al. and Grambow and Poinssot.
More studies are required to improve the accuracy of
estimation of the release of Pu isotopes.

Thanks, Cleita. That's why I posted. Few who know are talking about Fukushima in public.

Great. And I gave you sources in #105 that showed where it was found 25 miles away from FNPP.

Right. But it's plutonium and found 25 times further from the plant than you reported in #103.
