The report provides reference data and calculation methods for evaluating environmental radiofrequency exposure levels from various emitters.

Plain English Summary

Summary written for general audiences

The document illustrates methods for calculating power density and other values associated with environmental radiation from radiofrequency emitters. The report notes that biological effects research precludes specific conclusions about hazardous levels, though general exposure guidelines have been established.

Why This Matters

It provides the fundamental relationship between electric field strength and power density for plane waves in free space. Calculation examples demonstrate the method for a UHF TV station with a 700-foot tower and a radar facility with a 4-foot parabolic dish.
