Title: Radiation detector

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.

  • A radiation detector system used in aerial dosimetry in which an inorganic scintillation crystal detector and spectral filter are coupled to a photomultiplier tube and the requisite electronic circuits is described. The crystal detector is pointed toward an area to be monitored for x-ray or gamma ray and the resulting optical radiation therefrom is applied to the photomultiplier tube for converting to an electrical output therefrom which is monitored to indicate the radiation dosage.

  • The detector of the invention relates to the field of X or gamma photon detection. It is particularly adapted as a measuring chamber in conventional radiology and as a detector in scanography. It comprises at least one transformer for transforming X or gamma photons into light photons and at least one transformer for transforming light photons into electric signals representative of the energy of the incident X or gamma photons. The transformer for transforming X or gamma photons into light photons comprises a photoconducting layer and an electroluminescent layer between two electrodes which are brought to a biasing potential. Themore » transfer electrode may be formed by a schottky barrier. The transformer for transforming light photons into signals comprises a photosensitive layer, as a photovoltaic cell, on a substrate.« less
