How is polonium-210 used in anti-static products? Why is its presence in commercial products (eg. anti-static hair brushes) a concern?

Answer 1

Gamma rays emitted by Po-210 ionize air. Ionized air is a better conductor of electricity than normal air. The increased conductivity of ionized air helps discharge static charge into the ground.
