Strontium-90 is the material most commonly used to produce beta particles.
There is a very simple reason for this: beta particles are electrons.
During the process of radioactive decay, a beta particle will be released.
For example, a radioactive carbon-14 atom releases a beta particle to become nitrogen-14.
The beta particles would arrive at any moment, the protons, within hours, and they bore his death.
Beta particles are able to penetrate living matter to a certain extent and can change the structure of struck molecules.
Technetium-99 is used as a gamma ray-free source of beta particles.
In the process, it simultaneously emits two beta particles, or electrons.
Xe would be able to decay releasing only beta particles.
Beta particles can penetrate the skin but can be stopped by metal.
