Electromagnetic Field Overexposure Indicator

"There is a need for a personal radiofrequency radiation (RF) alarm that has the ability to detect high levels of electromagnetic field exposures, in both near and far-field situations, so that personnel can perform their duties without health hazards inenvironments mandated by DOD operations. This project will develop a small, inexpensive portable alarm to detect overexposures to RF electric and magnetic fields, up to extremely high intensities; at the latter, electronic devices could be inactivated.The approach is to use a passive device, based on the biosynthesized polymer diazoluminomelanin (DALM) suspended in an agar gel, for detecting, indicating with an alarm, and recording the exposure. The system would have a redundant active electroniccomponent, which would provide alternative audible and visual alarm features. The DALM and the DALM-gel technologies were invented or developed by Air Force Scientists; Beam Tech Corporation (BTC) has exclusive license to the biological and chemicalsynthesis of DALM. BTC will also test and evaluate to prototype system to determine operational limits of performance."
