Survey meter is a device for radiation exposure and dose rate measurements which is mainly used in radiation protection. The main purpose of this work is to present testing results of a designed surveymeter by comparing with a calibrated Peranuk surveymeter. The designed surveymeter consists of a NaI(Tl) scintillation detector as gamma radiation sensor with an ATMega328P processor as signal processing system and a 3.5-inch LCD as a data display. From the testing results, a count rate (cps) to dose rate (Sv/h) conversion factor of 0.0254 was obtained with dose rate reading deviations range from 0.03% to 6.26%.
