Tokaimura doses -- a retry of an earlier posting
Apparently the RADSAFE listserver has quality control aspirations. It seems to
ignore every other message I attempt to post.
Trying again:

Jim Dukelow comments:
This may be a "stupid lawsuit", although the fermented soybean maker is trying
to recover continuing losses arising from public reaction to their location 10
km from Tokaimura. The public reaction may not be rational, but it is
apparently real.
Regarding "no significant contamination", I was of the same opinion myself.
However, the 17 August 2000 issue of Nature has a Brief Communication "Neutron
dose estimates from 5-yen coins" by Masuchika Kohno and Yoshinobu Koizumu of the
Department of
Nuclear Engineering at Kyoto University.
They collected 5-yen coins (with 37% zinc content) from various
locations around the Tokaimura facility and measured the Zn-65 resulting
from neutron irradiation of the coins. Inferred neutron doses to the
coins were calculated using the transport codes DOT and MORSE and
converted to ambient dose equivalents (mSv) of 220mSv at 100 meters, 6
mSv at 350 meters, and 1.8 mSv at 550m.
Now, I'm not so sure that doses and contamination were trivial.
Best regards.
