Jim, Emil and others,

the 'm' must be milli not mega.
We perform biossay measurements on faces specimens with a detection limit of
1 mBq = 0,001 Bq for Am-241 and we count hours not days. For the same
nuclide we perform gamma-spectrometry on air-samples, detection limit is
about 20mBq/cubic-meter at a counting time 1-2 hours.
