This article presents the design and development of a digital desktop gamma radiation monitoring system using Geiger–Muller tube detector and microcontroller. The radiation detector, battery, signal processing circuits, and the microcontroller board are housed inside a tabletop wooden model with an analog watch and a digital display of radiation dose rate. The alarm level has been set at 1 μSv/h and indicated through buzzer and LED. The system has been calibrated using 137Cs standard source and has a sensitivity of 0.7364 cps/μSv/h. This model can be displayed on any table/desk or kept near a doorway to continuously monitor background radiation level, without drawing public attention, to detect any movement or presence of radiation source.
