    Abstract: A direct ion storage (DIS) radiation detector or dosimeter has a design that is easy and low cost to manufacture using semiconductor processing techniques. The detectors include internal communications interfaces so they are easy to read. Different interfaces, including wired, e.g. USB ports, and wireless interfaces, may be used, so that the dosimeters may be read over the internet. The detectors can thus be deployed or used in a variety of detection systems and screening methods, including periodic or single time screening of people, objects, or containers at a location by means of affixed dosimeters; screening of objects, containers or people at a series of locations by means of affixed dosimeters, and surveillance of an area by monitoring moving dosimeters affixed to people or vehicles.

    Abstract: The detector system includes three substantially similar detectors (10, 10') each of which includes an ionization chamber having a pedestal therein mounting a charged electret. Two chambers are completely sealed except for an equalization aperture. However, gamma rays produce ionization that neutralizes portions of the electret charge in these sealed chambers. The third detector has filtered inlet opening (42), which permit entry of radon gas, and responds to gamma rays and radon gas. By keeping the three units together until the test starts, one of the sealed containers can have the charge on its electret measured at the beginning of the test in order to provide a baseline measurement. At the end of the test, the charges on the other two electrets are measured and by appropriate calculations, an accurate measure of radon concentration at the test site can be obtained.
