Or buy some bananas. You'll get a positron every once in a while from the occasional Potassium-40 decay.
- gus_massa 2y agoI had to look up. Most of the radioctive potassium 40 in bananas decay by electron emmision. A tiny part by positron emision 0.001%. So you will get a lot of noise in the radioacivity detector.
