Quickly identify radioactive materials with a pocket-sized ion chamber. Built from standard parts for easy manufacture and low cost. by Carlos Garcia Saura: Radioactivity is invisible and can be harmful to life. The goal of this project is to provide a simple device that could prevent...

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)...

Robert Gawron has been working on a semiconductor radioactivity detector project: Currently I’m trying to make a working version of a radioactivity detector that uses semiconductor as a sensor. It’s a different approach than Geiger-Muller detectors, more complicated, but also...
