Assembled DIY Geiger Counter Kit Module Nuclear Radiation Detector LCD Circuit Diagram Geiger counter, also known as Geiger-Müller (G-M) counter, detects ionizing radiation such as alpha particles, beta particles and gamma rays using the ionization effect produced in a Geiger-Tube. The Geiger-Tube (GMT or GT) is filled with an inert gas such as helium, neon, or argon at low pressure, to which a high voltage is applied. Geiger-Muller tube operation (Source: Wikipedia) The following circuit (originally published on Elektor July 2006 magazine) illustrates how a GM tube can be used with some basic electronics to make a radiation detector, often known as Geiger counter. The circuit uses two 555 timer ICs. The 555 timer then drives a small speaker directly, making a 'click' noise each time the Geiger tube detects radiation. Use an IC socket for the 555 timer chip, so you don't fry the chip when trying to solder it into the circuit, also it makes it easier to replace if you make a wrong connection and fry the chip.
The electronic circuit of a Geiger-Müller counter. MC34063 is a DC/DC converter used to produce required high voltage, one of it's advantage over a simple NE555 or similar generators in this circuit is that it can monitor the output voltage and adjusts parameters to make it stable (R3, R4, R5, C3).
DIY Portable Radiation Detector using Geiger Counter Module Circuit Diagram
Too make this Geiger counter work, there needs to be two parts of this circuit; the high voltage power supply, and the detector circuit. In the diagram above, the high voltage circuit consists of a 555 timer driving oscillator driving a transformer. The 555 timer generates a square wave that, through a resistor, turns on and off a MOSFET Before mounting the PCB inside the case, check to make sure the entire Geiger Counter circuit functions. Background radiation will cause the Geiger Counter to click about 12—22 times a minute depending on your location. When you are satisfied that the circuit is working properly we can mount the circuit inside the case.
