  • METHOD AND APPARATUS FOR DETECTING ALPHA PARTICLES IN A SAMPLE CONTAINING SAMPLE MEDIA AND WATER
    Publication number: 20230349827
    Abstract: A method of detecting alpha particles may include providing a layer of a scintillating slurry comprising a granular scintillating material in water onto a measurement surface of a sample; positioning the sample having the scintillating slurry within a detection chamber of detection apparatus; detecting photons produced by the granular scintillating material in the scintillating slurry when the granular scintillating material is excited by ionizing alpha radiation emitted by alpha particles within the sample using a photon detector and generating a corresponding output signal; and removing the sample and the scintillating slurry from the detection chamber.

  • Directional radiation detection apparatus and method using inverse collimation
    Patent number: 9261605
    Abstract: The present invention provides a radiation detector for detecting both the intensity and direction of one or more sources of radiation comprising a radiation sensor, an inverse collimator that shields the sensor from at least a portion of the incident radiation originating from the direction in which the inverse collimator is pointed and a means for pointing the inverse collimator in different directions.
