An alpha detector (10) for application in areas of high velocity gas flows, such as smokestacks and air vents. An odd-numbered plurality of spaced apart signal collectors (13) are placed inside an enclosure, which would include smokestacks and air vents, in sufficient numbers to substantially span said enclosure so that gas ions generated within the gas flow are electrostatically captured by the signal collector means. Electrometer means (17) and a voltage source (16) are connected to the signal collectors to generate an electrical field between adjacent signal collectors, and to indicate a current produced through collection of the gas ions by the signal collectors.
