Hygienic standardization of electromagnetic fields of radar systems

Radars operating in the frequency band above 300 MHz may represent a danger for the population. The applicability of the energy principle of standardization to regulation of electromagnetic fields in populated points is analyzed. Equations are derived for hygienic standardization of exposure to electromagnetic fields based on medical and biological research and the corresponding values of energy flux density created by weather systems. The equations confirm the correctness of the principle of differentiating electronic devices according to classes on the basis of the fields which they radiate. The energy approach to standardization in the millimeter decimeter waveband is generally incorrect, but can be useful in establishing the variation of maximum permissible level as a function of time for individual types of radars.
