BBC is saying levels in Tokyo are now at 210, with 100 being the safe
level for infants (of course, unfiltered Tokyo tap water has not been
safe for infants for decades, without needing radioactivity...):

But the latest file at http://eq.wide.ad.jp/, which is 1pm today, is
showing 19 (5.3 yesterday). Quite different from 210 (I checked, the
units being quoted are the same). The BBC have not given the source for
their data, but has anyone seen a different data source?
