A kit to make the electron detector variant of the DIY Particle Detector project.
This open hardware project is a mobile low-cost detector for measuring ionising radiation like electrons from beta radiation (plus some gamma photons). It's an educational tool and citizen science device made for exploring natural and synthetic sources of radioactivity such as stones, airborne radon, potassium-rich salt or food and every-day objects (Uranium glass, old Radium watches etc.).
This project is developed by Oliver Keller at CERN, see full project details here.
This is a kit to make your own electron detector. A required metal enclosure (see the wiki) and a 9V battery are not included.
