In this study, the effect of the lead (Pb) shielding on the rate of cosmic rays generally charged particles coming through the atmosphere were studied. The measurements were all done indoors by using a prototype detector consisting of a 20 × 20 × 1.4 cm 3 KURARAY organic scintillator read by 3 mm 2 SensL silicon photomultiplier. The measurements were carried out by using lead plates of different thickness in order to shield the charged particles and investigate Rossi transition curve by using

The Cosmic ray fluxes over the building (sea level firstly simulated by using the CRY software and then the attenuation effect of the construction elements on the measured cosmic ray rate was carried out by using GEANT4 simulation program and this effect was taken into account in the given results.
