Title: DALM Personal Radio Frequency Radiation Dosimetry System
Agency / Branch: DOD / USAF
Contract: N/A
Award Amount: $749,961.00


Beam Technology Corporation is prepared to develop an innovative personal Radio frequency Radiation Dosimeter based on concepts originally enunciated by Dr. Johnathan Kiel, The approach will use a technology that promises to be much more versatile than currently available methods of measurement, which often employ E-field probes and meters. The objective is to use a novel chemical, Diazoluminomelanin (DALM), as a sensitive material for detection of the radio frequency radiation (RFR) exposure. The DALM will be employed as a thin film in the detection part of the dosimeter, in a sealed container to be designed. During the Phase I Project, we will explore the use of a system which would have the DALM film exposed to a specified frequency of light during the period of RFR exposure and subsequently determine the extent of RFR exposure by measuring the slow fluorescence emitted by the film (in a reader to be designed) upon pulsed activation by light of the same or a similar wavelength. Since there is no published literature describing this technology, a second approach which will be explored is to activate the DALM film to emit light, also in proportion to the RFR exposure, using either an existing Quantitative Luminescent Imaging System (QLIS), or a modification thereof designed specifically for this dosimetry system. The DALM film would be designed to allow for reading on a daily basis (to determine exposures of moderate to high intensity only), or at 3-month intervals (for reading a combination of both. Potentially, the system could be designed to indicate that an RFR exposure which is currently occurring (above a to-be-determined intensity level).
