We got more [radiation] then that from an emitter in a high school physics classroom.
To be fair, that's a point source that you generally wouldn't hold in your bare hand for long, let alone rub all over your body for hours and hours on end, whereas (I'm assuming) that web-cammed counter (which was getting around 9000 hits[1] when I viewed it earlier) would be measuring the pervading levels in all around, whether from particles in the air[2] or that gentle gamma glow that really enhances the Hulk's complexion and "slows the seven signs of raging"[3].
OTOH, I suspect you might be able to get more than it was indicating by placing it on a granite worktop (doing some quick conversion between units in my head, but probably wrongly, because it's been a while since I looked at granite).
[1] web-type, not ionising particle type.
[2] Must go and look for a current wind-chart for Japan, as all the scary pictures of fall-out I've seen so far seem to suggest a general tendency towards airflow and nucleotides going east from that area (even at short distance, therefore not purely jet-stream height) and not towards any of the significant otherwise unharmed population centres of the country. But they are scary-type pictures made to scare the merkins off of the 'Merkins, so could be less than accurate.
