Various radioactive objects can be examined using a Geiger counter. Paper, aluminum foil, aluminum plate, and lead plate can be used to block emissions from the objects. Place the source on the bench.

James said: Hey Max,your comment about DIY Geiger counters reminded me of a demonstration that I saw as a high school student… Back in the early '90s, Atomic Energy Canada hired a spokesman that ...

It uses a Geiger counter they brought with them as an enclosure, re-purposing the analog gauge to reflect the level of active radio signals in the area. You’ll find their demo clip embedded ...

[Henrik] really turned out a nice little Geiger counter board based on a cold war era Geiger tube. It works in much the same way as other projects along the same lines. It does run on batteries if ...

The method in its original form was somewhat tedious and troublesome, but the invention of the 'point' or Geiger counter made possible much more rapid counting, the counting of β- as well as of ...

The basic principle is that if a radioactive source is placed between two Geiger counters connected to a coincidence counter with resolving time τ, and if, in the course of successive ...
