Pocket Photodiode Geiger Counter

Description

Pocket Photodiode Geiger Counter Kit
Experience Level: Intermediate
A DIY geiger counter that uses a PIN photodiode as a substitute for an expensive Geiger-Mueller tube. It detects alpha and beta radiation particles. The circuit is soldered onto a small protoboard and everything is placed in an aluminum enclosure. Copper tubing and a piece of aluminum foil is used to help filter out noise and RF interference.
