Abstract
Alpha particle detecting devices are disclosed that have a chamber that can hold a fluid in a tensioned metastable state. The chamber is tuned with a suitable fluid and tension such that alpha emitting materials such as radon and one or more of its decay products can be detected. The devices can be portable and can be placed in areas, such as rooms in dwellings or laboratories and used to measure radon in these areas, in situ and in real time. The disclosed detectors can detect radon at and below 4 pCi/L in air; also, at and below 4,000 pCi/L or 300 pCi/L in water.
Claims19
A radon detecting device comprising a chamber holding a fluid in a tensioned metastable state wherein the chamber contains the fluid alpha particle detection tension so that cavitation events occur in the fluid when alpha particles are present, wherein a radon contaminated material is placed in contact with the fluid.
