Robert Gawron tipped us with his latest build. He writes: Today I will show a very simple ionization chamber that can detect radioactivity. I was able to detect with it ionizing radiation from a smoke detector (Am241 isotope). It’s also immune to electromagnetic interference (EMI) due to a good shielding. Radioactivity detection using very simple […]

€15 IoT Geiger Counter using ESP8266

https://www.electronics-lab.com/e15-iot-geiger-counter-using-esp8266/

Geiger counters are devices 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. The Geiger–Müller tube or G–M tube is the sensing element of the Geiger counter instrument […]
