Abstract

An apparatus combination useful in carrying out work within hazardous environments, especially radioactive environments. The combination includes (a) a plurality of portable input modules, each portable input module being capable of receiving video, audio and radiation dosimetry communications data and transmitting that data via a single portable input module data transmission cable, (b) a relay module for receiving the communications data from the plurality of portable input modules via each of the single portable input module'"'"'s data transmission cables and for transmitting that data via a single relay module data transmission cable, and (c) a communications output station for receiving the communications data from the relay module via the single relay module data transmission cable and for translating that data into user recognizable video, audio and radiation dosimeter data output forms. Use of the invention has been found to markedly reduce the costs associated with set-up, testing, operation and disassembly of data and communications receiving equipment necessary within hazardous work areas. Moreover, use of the invention has been found to markedly increase the ability of the work coordinator to conduct work within a hazardous area in a safe and efficient manner.
