Radiation survey meter with integrated GPS

A portable radiation survey meter has been designed, developed for in-situ radioactivity measurements in field areas to accomplish gamma ray surveys for geological, geochemical, and environmental mapping. The instrument measures radioactivity along with latitude, longitude, and ambient temperature. Additional significant features are variable audible alarm indications above threshold limit, in-built memory storage of the complete data, subsequent data retrieval through USB drive/PC and PC based software for data compilation. Automatic shutdown of the instrument in ideal state conserves the battery power. The acquired data along with the geographical coordinates can be integrated with geological mapping tools for data interpretation. (author)
