Web23 de out. de 2024 · The HV supply has only to source less than a mA. If an ionizing particle passes through the GM-tube, it will cause a brief discharge current, which in turn will give a brief pulse over the resistor. You'll need a radioactive source to test it. The higher the radioactivity the more pulses per minute you'll get (and the more unhealthy it is!). WebStep 1: General Description and Schematic. The working of this counter is very simple. A high voltage is generated and applied to a GM tube. When a radioactive particle hits the gas inside the GM tube it conducts a short time. The current that flows through it is amplified and counted with a microcontroller. how to say sandwich in french
