“…However, this condition was reversible usually within 30 minutes. Other published studies on the effects of EMP on vertebrates include SKIDMORE and BAUM'S (1974), BAUM et al's (1976) and BAUMS (1979) cellular work on rats and dogs. None of these studies found significant differences between EMP-exposed and control individuals.…”

Six estuarine fish species common to Chesapeake Bay in Maryland and Virginia, USA were exposed to electromagnetic ulses (EMP) of 100-kv/m airfield strength at a risetime of ca. 10 nanoseconds per pulse. EMPwas derive1from a 2-stage Mam generator. Results infer that acute mortality will not occur in fishes swimming near the surface at distances > 50 m from a U.S. Navy electromagnetic pulse radiation environmental simulator for ships (EMPRESS 11) being field tested off the USA coastline.

“…Earlier studies of exposure to electromagnetic pulses showed no effects on fertility or on anatomical abnormalities in progeny (rodents: Baum et al [1976]), and no effects on litter size or abnormalities in newborn pups (dogs: Baum [1979]). The results obtained from the UWB-exposed rats con®rm that male embryos/fetuses exposed to an UWB electromagnetic ®eld from days 3±18 of gestation are capable of fertile matings at sexual maturity.…”

Several investigators have reported teratologic effects of electromagnetic field exposure. The majority of these studies have been performed at levels of exposure that could produce substantial heating of the animals. New and unique sources of ultra-wideband (UWB) electromagnetic fields are currently being developed and tested that are capable of generating nonthermalizing, high-peak-power, microwave (MW) pulses with nanosecond (ns) pulse widths, picosecond (ps) rise times, and an UWB of frequencies. Our study was performed to determine if teratological changes occur in rat pups as a result of (i) daily UWB exposures during gestation days 3-18, or (ii) as a result of both prenatal and postnatal (10 days) exposures. Dams were exposed either to (i) UWB irradiation from a Kentech system that emitted a 55 kV/m-peak E field, 300 ps rise time, and a 1.8 ns pulse width, average whole-body specific absorption rate 45 mW/kg; (ii) sham irradiation; or (iii) a positive control, lead (Pb) acetate solution (2000 microg/ml) continuously available in the drinking water. Offspring were examined for ontogeny (litter size, sex-ratios, weights, coat appearance, tooth-eruption, eye-opening, air-righting, and ultrasonic stress vocalizations). Male pups were tested on various performance measures (locomotor, water-maze learning, and fertilization capabilities). The pups postnatally exposed were examined for hippocampal morphology and operant behavior. Behavioral, functional, and morphological effects of UWB exposure were unremarkable with these exceptions: (i) The UWB-exposed pups emitted significantly more stress vocalizations than the sham-exposed pups; (ii) the medial-to-lateral length of the hippocampus was significantly longer in the UWB-exposed pups than in the sham-exposed animals; (iii) male offspring exposed in utero to UWB mated significantly less frequently than sham-exposed males, but when they did mate there was no difference in fertilization and offspring numbers from the sham group. There does not appear to be a unifying physiological or behavioral relationship among the significant differences observed, and our findings could be due to the expected spurious results derived when a large number of statistical comparisons are made. Significant effects found between our positive-controls and other groups on numerous measures indicates that the techniques used were sensitive enough to detect teratological effects.

“…Increased and decreased lymphocyte and total leukocyte counts in EMP exposed rats were also found but less frequently than changes in platelet or erythrocyte count. When the EMP exposure was continued to 94 weeks to a total of 2.5 x 10' pulses (note: 1.86 x io« pulses by calculation), hematological changes were no longer evident [Baum et al 1976]. In addition, bone marrow ceUularity was not different between groups [Skidmore and Baum 1974].…”

“…In addition, bone marrow ceUularity was not different between groups [Skidmore and Baum 1974]. Because of these inconsistencies among hematological and hemopoietic endpoints and the absence of effect at the end of the 94 week exposure, it was concluded that EMP effect was not hazardous to rodents [Skidmore andBaum 1974, Baum et al 1976}. In a later publication, Baum (1979] did not find any effects on hematotogfol and hemapoiesis endpoints in four male and five female beagle dogs exposed to the 447 kV/m EMP pulses for 8 hr/day, for a total 45 days and 5.8 x 10 s pulses (note: 6.48 x if/ pu]ses by calculation).…”
