Abstract Observed biological
effects of pulsed microwave radiation are reviewed and the exposure standards
for microwave radiation are summarized. The review indicates that the
microwave auditory effect is the only well-established specific effect in
realistic exposure situations. The threshold for the effect depends on the
energy density per pulse and may be as low as 20 mJ/m2
for people with low hearing threshold. Energy density limits have been
included in the most recent exposure standards. A new battery-operated,
hand-held meter developed for measurements of pulse power densities around
scanning radar antennas is described, and a simple new model for the
calculation of power density in the main beam of radar antennas is presented.
In the near field measured values differed from the calculated values by 2-3
dB. Key Words: Radar, Microwave pulse, Microwave auditory effect, Power density. |
