In a nuclear accident situation there is a need for a long range stand-off monitoring system, since severe environmental contamination with radioactive nuclides can make in-situ methods hazard prone. In this paper, the design and simulation of phased arrays using log periodic dipole antennas for potential application in the detection of radiolytic components in water, created out of the exposure of the ubiquitous water molecule to gamma radiation is presented. Various configurations like linear and planar array designs were studied. The proposed array designs could be mounted on an unmanned air vehicle, balloon or a satellite to monitor large-scale nuclear incidents. The antenna response and array response were studied in terms of characteristics like system equivalent flux density, sensitivity, gain and polarization. From such studies, a suitability evaluation for the design to detect radiolytic components is performed. © 2016 IEEE.
