Introduction

A Geiger counter is an instrument used for detecting and measuring ionizing radiation. Also known as a Geiger–Mueller counter (or Geiger–Müller counter), it is widely used in applications such as radiation dosimetry, radiological protection, experimental physics, and the nuclear industry.

Geiger counters are used to detect radioactive emissions, most commonly beta particles and gamma rays. The counter consists of a tube filled with an inert gas that becomes conductive of electricity when it is impacted by a high-energy particle.

Étape 1 - Soldering the geiger counter

This is a timelapse of the assembly process of the geiger counter

Étape 2 - Using the geiger counter with an arduino

Connect the P3 Pin GND, 5V, VIN to arduino GND, 5V, Digital 2 respectively.

Then in the arduino software open the file: spi_rad_logger.ino which you could find here

https://drive.google.com/open?id=1BBhsOjpKFHZ5vheR6OtunmriIw6JLzbc

Be sure to change the Serial.print(cpm) command to Serial.println(cpm) in the void loop(){} for better readability.

Download the program and open the serial port window by clicking on the scope on the upper right corner.

Then we’ll get the radiation value displayed in CPM, counter per minutes which could be

converted to uSv/h with the index 151(151CPM=1uSv/h for M4011 GM Tube).
