Abstract
A lower power consumption gas leak detector device includes an ionization chamber with a radioactive source and pointed electrode in close proximity thereto supported within the ionization chamber. The pointed electrode provides a region of high electric field with a lower applied voltage so that the gas leak detector provides a significantly larger current signal for a particular gas leak rate with the device operating in the high voltage avalanche region than if the device was operating in the saturated current region of the current versus applied voltage characteristics of the device.
