摘要：

In the present paper a novel cosmic-ray experiment in the Institute of Physics, Belgrade is described. A couple of plastic scintillator detectors arc in continuous operation since December 2001, measuring cosmic muon flux at ground level and at shallow depth underground (25 m of water equivalent). Quasi-periodic variations of muon flux in the period 2002-2004 are studied, and strong correlation with the solar activity is found. Sporadically, sudden decreases in CR intensity are detected, mostly as consequences of coronal mass ejections propagating toward the Earth. A small anisotropy in cosmic rays is also detected.
