"background" is the concentration originating from the atmospheric nuclear
tests. It is in no way zero! I do not the situation in the USA, but in
Europe a careful environmental monitoring programme has to be performed in
the vicinity of a nuclear reactor site before the start of the NPP - just
in order to establish the already present environmental radionuclide
concentrations.

No, this is not possible because of the atmospheric nuclear tests.

The lower limit of detection has to be clearly declard as such in order to
be able to distinguish it from real numbers. By the way a result without
stating the error is unacceptable - many people use numbers to claim
radionuclide concentration increases, though the numbers are all within the
error.
