radioactivity decay & penetration

Radioactive decay The radioactivity sensor is normally connected to a standard Geiger-Muller tube and can produce a radioactive decay curve in ‘real-time’. This is a very convincing display of radioactive decay. Protactinium, with its...

radioactive half-life

Radioactive materials decay, or lose their radioactivity, in a predictable way. If you have a fast decaying source, such as Protactinium with a half life of just 72 seconds, you can take a series...
