  The Belgrade underground laboratory consists of two interconnected spaces, a
ground level laboratory and a shallow underground one, at 25 m.w.e.. The
laboratory hosts a low-background gamma spectroscopy system and cosmic-ray muon
detectors. With recently adopted digital data acquisition system it is possible
to study simultaneously independent operation of two detector systems, as well
as processes induced by cosmic-ray muons in germanium spectrometers.
Characteristics and potentials of present experimental setup, together with
some preliminary results for the flux of fast neutrons and stopped muons are
reported.
