[ RadSafe ] Activity question

[BLHamrick at aol.com]

I also think that when it comes to setting low-level threshholds,  scientists 
recognize there is little difference between 10, 50, 70 or 100 Bq/g,  but you 
have to settle on some number eventually for regulatory purposes.

You are  making the assumption that bureaucrats used a scientific/technical
basis  for setting the level. My guess is that  it probably had to do  with
either a 1 nCi commodity like a lantern mantle or a detectability  issue.

I believe the original  question related to the
scientific/technical  basis
for the 70Bq level rather than the  administrative/bureaucratic
basis. Why
was 70bq selected-- as opposed to 10, 50, 100, or   63.749 Bq
???
