Abstract
In a glow discharge starter, a layer of lanthanum is present on one of the conductors and the gas filling is a Penning mixture. The glow discharge starter does not contain radioactive material. The delay time between the application of a voltage between the conductors and establishing a glow discharge remains short during the whole life of the glow discharge starter, even when the starter was kept in a room with a low light level for a prolonged time.
