Ultrawideband radiation and pentylenetetrazol-induced convulsions in rats.

View Original AbstractUWB radiation showed no effect on drug-induced seizures in rats, but incomplete exposure details limit safety conclusions.
Plain English Summary
Researchers exposed rats to ultrawideband (UWB) electromagnetic pulses while inducing seizures with a drug called pentylenetetrazol to test whether these high-power, ultrashort electromagnetic pulses could cause brain tissue damage. They found no effect of UWB exposure on seizure activity compared to unexposed animals. This suggests that UWB radiation at the levels tested does not produce the kind of electromagnetic transients that would damage brain tissue.
Study Details
New non-ionizing pulsed systems using ultrawideband (UWB) require safety assessment before they can be used by either military or civilian communities. The development of directed energy weaponry intended for use against electronically vulnerable targets, as well as ground-probing radar systems, have used fast-rise-time high-peak-power electromagnetic pulses characteristic of UWB emitters. It has been postulated that these ultrashort pulses might produce electromagnetic transients resulting in tissue damage.
Several challenges to this notion have been posed, however. One report found that rats exposed to UW...
The data from the current study show no effect of UWB exposure on PTZ-induced seizure activity, thereby not supporting the tissue damage concerns, at least for the exposure parameters used here.
