Abstract: We have designed and developed a compact, wireless-networked radiation sensor array. The sensor system provides high sensitivity gamma photon detection and remote warning for a broad range of radioactive materials. This sensor identifies the presence of a 1μCi Cs137 source at a distance of 1.5 m. The networked array of sensors presently operates as a facility sensor tracking the movement of radioactive laboratory check-sources. Our goal has been to apply this architecture for field-security applications by incorporating low-power design with compact packaging. The performance of this radiation measurement network is demonstrated for both detection and location of radioactive material.
