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: Dosimeters with wireless communications capability, upon actuation, communicate with a cell phone or other data capture and relay device (DCRD) with an application that allows communication with the dosimeters. The cell phone or other DCRD is a single device or part of an ad hoc network. The cell phone or other DCRD, once it receives raw data from a dosimeter, relays the data to a central station using mobile telephone or Wi-Fi or other communications networks. The data is processed at the central station, and available over the internet or cell phone.

Abstract: Disclosed is a radiation detector, comprising a chamber or cavity that produces charge carriers when radiation is incident thereon. The chamber is defined in part by a deformable plate along one side of the chamber or cavity; and a rigid plate spaced and electrically insulated from the deformable plate. A charging voltage source is present for applying a voltage to the deformable plate; such that wherein the deformable plate is attracted toward the rigid plate by electrostatic forces when charged by the charging voltage source, and moves away from the rigid plate when charge carriers produced in the chamber or cavity by incident radiation reduce the electrostatic forces between the deformable and rigid plates.

Abstract: A mechanism for supporting a charge collecting electrode in the chamber of an ion detector includes an insulator that is mounted in the chamber and is attached to the electrode. A first magnet is used to establish a magnetic field in the chamber, and a second magnet is attached to the electrode. The magnet on the electrode then interacts with the magnetic field to stabilize the electrode in the chamber between the insulator and the first magnet.

Abstract: A photodetector comprising a photoemissive surface capable of liberating photoelectrons. Photoelectrons are detected by a MOSFET having a floating gate, which is suitably charged before measurement in such a way that photoelectrons can cause a change in charge of the floating gate. The detected change indicates the amount of light received by the detector.

Abstract: A method for detecting ionizing radiation by allowing the radiation to affect the surface of the floating gate of a MOSFET transistor through an air or gas space. For this purpose, an uncovered area is formed on the surface of the floating gate of the MOSFET transistor forming the detector. The MOSFET transistor is used so that a charge is formed on its floating gate, the charge changing as a result of the ionizing radiation the transistor is exposed to. The radiation dose is determined by the change which takes place in the charge on the gate.
