Abstract
A radioactive static eliminator gun has a cartridge (7) connected to a high pressure air supply (8). Within the cartridge (7) a radioactive source (6) which generates alpha particles is located coaxially along the central longituidinal axis. The alpha particles collide with the high pressure air stream passing through the cartridge thereby generating ions. With this arrangement the ion concentration is greatest at the core of the air stream which ensures that the greatest number of ions is delivered to the surface requiring static elimination. The radioactive static eliminator gun provides improved efficiency in removing static an is particularly suited to use in paint spraying of metal surfaces where the electrostatic forces at the surface of the metal may not be strong enough to attract ions in the air stream emerging from the gun.
