Abstract : The experimental data reported represents a major accomplishment in that for the frequency used, 5500 MC/sec, it was demonstrated that lens opacification was directly related to average power density irrespective of whether the energy was in a continuous or pulsed mode of emission. By using a closed wave-guide system, it was possible to avoid all of the free-field variables of microwave radiation and to accurately determine the quantity of energy entering the eye. Comparison to a similar investigation at a different frequency (10, 050 MC/sec) revealed that the lenticular effects had practically the same time-power dose relationship. The findings demonstrate not only that various microwave emission factors can be segregated and controlled but also that exact time-power relationships for cataractogenesis can be determined by biological assay. Thus, with confidence in the replicability of the exposure methodology, it is planned to obtain additional data in accordance with the experimental protocol developed for this study. (Author)
