Abstract
Un aparato para la detección de radón para la prospección de mineral de uranio, que comprende en combinación un alojamiento protector no perforado que definen un, volumen encerrado y que tiene una abertura, adaptándose dicho alojamiento para enterramiento en la tierra con dicha abertura dispuesta en su lado inferior, un cuerpo no protegido de material de detección de partículas alfa dispuesto dentro de dicho alojamiento y asegurado al mismo para exposición directa a los gases del suelo que entran en dicho volumen encerrado a través de dicha abertura y, una membrana permeoselectiva no porosa que cierra dicha abertura por la cual deben entrar los gases del suelo que dejan el suelo y que entran en dicho alojamiento, atraviesan el espesor y que dejan dicha membrana, estando sustancialmente libre dicha membrana de contenido que emite tanto 220Rn como 222Rn.
