Colourbox Circuit Diagram Build Your Own Easy Radiation Detector Using a Geiger Counter Module Introduction Radiation detectors are essential instruments for identifying high-energy […] 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 circuit diagram is shown in Figure 6. The parts needed are shown in Figure 7 and parts lists broken down by subassembly are given at each step. You will be assembling the circuit on a printed circuit board (PCB), the top of which is shown in Figure 8. In the subsequent steps, components involved in the active step will be shown in full
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. The key principal of Geiger counter operation is the Geiger tube, and how it sets up a high voltage on one electrode. This high voltage is like a steep mountain slope covered in deep snow, and all it takes is a tiny bit of radiation energy (akin to a skier going down the slope) to set off an avalanche.
Making a Geiger counter with 555 timer IC 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 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). 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.
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. This DIY nuclear radiation detector can measure and detect alpha, beta, and gamma radiation.
