This list was prepared by DOE utilizing the results of a multi-million dollar program of studies by a broad array of expert organizations. Again the “microwaves” issue is placed at the top. What are the microwave power densities that cause such concern? These are listed in Table 3. We see that there is a relatively slow drop of power density with radial travel from the rectenna boundary. Although the rectenna diameter is only 10 km, the area with power density above 0.01 mW/cm2 is 25 km in diameter. This level (.01 mW/cm2) is a factor of 500 below current U.S. (ANSIC905.1-1982) safety limits; and just about the level of safety limits reportedly applied in public areas of the USSR. Thus microwave levels outside the rectenna to which the general public may be exposed are far below safety limits. Yet because of some mystique attached to “microwaves” possibility of microwave exposure is considered a prime obstacle in
