Orofacial radiation detection device for detection of radionuclide contamination from inhalation

摘要

The present invention provides an orofacial radiation detection device for detection of radionuclide contamination from inhalation. The device includes a face mask including a support frame and an adjustable head strap connected to the support frame. Mounted on the frame are radiation detectors in selected locations so that when being worn by a person, the detectors are located in close proximity to the orofacial region of the person including their nose and mouth. The device includes an electronic controller connected to the detectors for controlling operation of the radiation detectors. The device includes a microcomputer mounted on the support frame and electrically connected to the electronic controller for processing signals from the detectors for allowing input from an operator, performing data analysis and detection algorithms, and outputting results. The detectors include beta and gamma detectors that, utilizing appropriate hardware processing and software algorithms, are able to determine if radionuclides are present in the orofacial area of a person suspected to have been exposed to airborne contamination.
