RF RADIATION HAZARD DETECTION AND WARNING DEVICES: PHASES I AND II.

Recognition that physiological damage caused by microwave radiation is a function of the time of exposure as well as the level of power density required the development of an RF radiation integrator. Phase I of the program resulted in an integrating Microwave Radiation Hazard Detector which accumulates incident electromagnetic energy over a 30-second interval and reads out the total value on a counter. Phase II of the program resulted in a ruggedized, portable, battery-operated RF radiation integrator which accumulates incident electromagnetic energy over a 30-second interval and actuates first, second or third level visible and audible alarms when total energies exceed 0. 3, 0. 6, and 3. 0 joulessqcm, respectively. Both instruments utilize E-CELL integration techniques. The E-CELL is a new electrolytic component in which transfer of a platable material between electrodes is proportional to the incident energy. The program included studies and procurement of antennae which were circularly polarized and which approximated hemispherical coverage. Author
