To study if protracted prenatal exposure to microwave irradiation at a frequency of 6000 MHz and at a power density level of 35 mW/cm² would result in significant changes in postnatal psychophysiologic growth and development.
Litters were culled to F1 a offspring. Mothers were rebred 10 days after weaning. Further investigations were completed on F1 b offspring.

Sex differences within groups were found in four behavioral tests and in blood data. Exposed females exhibited decreased learning ability in the water T maze test but the males were unaffected. Exposed females exhibited decreased activity levels, and males showed increased activity levels, in the open field test.
Significant differences between groups were revealed for: F1 b term fetal weight; F1 a eye opening, postnatal growth to the fifth week, water T-maze and open field test results; and several organ/body weight ratios.
These findings indicate that exposure to 6000 MHz irradiation at this power density level may result in subtle long-term neurophysiologic alterations in the absence of morphologic alterations.
