Abstract:

The goal of this project is to reconcile the guidelines for human exposure at the frequency interface 300 GHz between millimeter waves and infrared lasers and to derive means for this reconciliation in terms of existing and proposed scientific data requirements. To this end, a two-day workshop was convened at Brooks Air Force Base on 21-22 January 1997 at which experts in the technology and biological effects of exposure to both millimeter wave frequencies and infrared laser optics presented papers on the state of the art in their respective disciplines. Several informal discussions and a final panel discussion illuminated the key questions requiring answers and proposed research that would help define these answers. A significant step toward future refinement of the exposure guidelines was the establishment of a six-person ad hoc committee, under the Chairmanship of Dr. Kenneth R. Foster, to serve as a liaison between radio frequency and infrared laser standards-setting organizations. This committee would determine research and modeling needs that would provide the basis, in terms of both field strength and averaging time, for a reconciled exposure guideline for humans at 300 GHz.
