Abstract:

The program undertaken under this contract was designed to investigate Raman and infrared spectrometric techniques as a method of detecting, quantifying and diagnosing molecular damage in biological compounds due to exposure to RF radio frequency radiation. The program emphasis was on the use of the Raman approach while only a preliminary evaluation of the infrared method was undertaken. It has been established that biological materials do undergo damage when exposed to RF radiation. It has further been concluded that molecular spectroscopy methods yield the data output necessary to generate RF radiation hazard parameters. The spectrometric approaches, however, have not been fully developed or refined. In the case of Raman spectroscopy fluorescence and sensitivity are problems. Infrared techniques appear satisfactory from preliminary data but the effect of the water-rich background matrices and the ability to do micro-damage assessment are not completely known.
