Protective Measures for Microwave Radiation Hazards: 750 to 30,000 Mc

Continuous exposure to a field intensity of 0.001 watt per square centimeter appears to cause no harmful effects to either animals or men. It is neither difficult nor expensive to make and use monitoring instruments to find out whether or not fields in excess of 0.001 watt per square cm exist in an area. It is well to remember that microwaves may be greatly intensified by reflections from objects which do not reflect light well. Consequently, it is necessary to use instruments sensitive to the microwaves in inspecting an area and to move them about the whole area to find out whether or not it is safe.
