An environmental monitoring system for a hazardous work area, such as a nuclear power plant, which monitors the radiation exposure of personnel working in the nuclear power plant and overlays a visual representation of the exposure data onto a video display of the location the personnel are working in. The apparatus includes a video source, such as a plurality of PTZ cameras, for providing video image signals of the work area. In the preferred embodiment, individual radiation exposure sensors provide signals representative of the radiation received by each worker in the work area. A computer, outside of the work area, is connected to the sensors for converting the sensor signals to a visual video representation of the sensor measurements. A gen/lock overlay unit is connected to the computer for combining the video image signals and the visual video representation of the sensor measurements wherein the visual video representations are overlaid onto the video images of the work area. In the preferred embodiment, a remote relay unit first receives the video image signals and the sensor signals adjacent to the work area and relays the video image signals and the sensor signals to the computer and the gen/lock overlay unit outside the work area through a fiber optic cable.</PTEXT>
