Abstract: A real-time wireless video exposure monitoring system comprising an exposure monitor, located at a field site, which detects the level of an environmental contaminant and supplies corresponding data via a serial data port to a serial-to-wireless bridge for real-time wireless transmission of the data to a wireless Internet access point. The system includes a video camera at the field site and a wireless video connection for transmitting video images from the video camera in real time to the wireless Internet access point. A client computer, which may be at a central station at a distant location, is adapted to connect via the Internet to the wireless bridge and the wireless video connection so as to receive real-time contaminant level data and real-time video, the client computer configured to provide real-time data recording and analysis.

Abstract: A real-time video radiation exposure monitoring system comprising a Geiger-Müeller meter and a video camera linked to a computer programmed to display video images from the camera simultaneously with data from the Geiger-Müeller meter. A radio modem provides wireless data communications between the Geiger-Müeller and the computer. One aspect of the invention is a retrofit of a conventional Geiger-Müeller meter to include a microcontroller with internal A/D converter enabling the meter to output instantaneous measurements in RS-232 serial format.
