Abstract

Detector de ionización que comprende una estructura de cámara en la que se incluyen medios que definen una primera cámara, medios que definen una segunda cámara dotada de medios para recibir gases del exterior de la misma y medios limitadores comunes entre las cámaras, que incluyen un electrodo común; un electrodo asociado a la segunda cámara, otro electrodo dentro de la primera cámara, que define una tercera cámara dentro de la primera y está por lo menos parcialmente abierto para proporcionar una trayectoria de ionización entre la primera y tercera cámaras; medios que incluyen una fuente radiactiva dispuesta por lo menos en la segunda cámara para establecer una corriente de ionización en la estructura de cámara citada y medios acoplados por lo menos desde el electrodo común para detectar cambios en la corriente de ionización.
