Abstract: Geiger Muller counter for detection of ionizing radiation was constructed mainly with GM tube and counting system to count tube output radiation signals. The counting system which is one of the important parts of the Geiger Muller counter and it was built with Arduino Uno microcontroller board. Arduino Uno board was used for input pulse signal detection and pulse counting processes by programming with Arduino C language. In this research SD card data logging shield was used to save the measured counts and relevant radiation dose with time stamp. The information of radiation dose (Sv), count per minute (CPM), gained from pulse detecting and counting system was displayed on LCD. One LED flashes and buzzer beeps whenever radiation signals were detected. In addition, GSM module sent SMS to mobile phone according to the program sketching in the Arduino board when Arduino based GM counter detect limited radiation dose rate. In this research firstly function generator (GWINSTEK AFG 3051) was used instead of GM Tube to feed input signal to pulse detecting and counting Arduino Uno board in order to confirm the program for the detection of input signal which is corresponding to the radiation event. Secondly GM counter high voltage (HV) power supply (400 - 506V) was developed for detection of ionizing radiation and counting system in order to count tube output signals. High DC voltage needed for LND-712 was built as high DC voltage bias supply to the anode of GM tube. Pulse counting system was developed to proceed the electric signals, which is generated by GM tube. The counting system detects the signal from the GM tube and the information of radiation dose (Sv), count per minute (CPM), gained from pulse detecting and counting system was displayed on LCD. Arduino, not only open source programmable device but also small the size and design, will give profit on the design and size of radiation detector for the purpose of portable institutional and field inspection of radiation survey meter.
