Orofacial radiation detection device for detection of radionuclide contamination from inhalation
First Claim
1. An orofacial radiation detection device for detection of radionuclide contamination from inhalation, comprising:
- a) a housing shell and a support frame, said support frame being contoured to cover an orofacial region of a person, said housing shell and said support frame being configured to be secured together defining an enclosure therebetween;
b) radiation detection means mounted in said enclosure so that when being worn by a person, said radiation detection means is located in close proximity to an orofacial region of the person;
c) electronic control means connected to said radiation detection means for controlling operation of the radiation detection means; and
d) computer processing means electrically connected to said electronic control means for processing signals from said radiation detection means.

Abstract
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.
