Doesn't that say Bq per cubic metre?

No, it says Bq per cm2

cm2 of what? cm2 isn't a useful measure AFAICS.- Hide quoted text -

cm2 is a perfectly useful measure of area, but as Tim has pointed out
that was a typo for cm3, which is a useful, if odd, measure of
volume. They had been reporting values per litre but obviously wanted
to take the numbers down an order of magnitude so used cm3 instead.

That looks like three orders of magnitude to me.
