Abstract:

The three elements of the research were designed to examine possible biological and medical effects of exposure to the near-field of Loran-C transmitters that operates in a pulse modulated mode at a carrier frequency of 100 KHz. Neurochemical studies tested the effects of single and repeated in vivo exposure to a simulated Loran-C type waveform on the rat brain biogenic amine and opiate receptor systems. We found AM-PM differences in the levels of amines but no field-related effect was detected. Number and affinity of opiate receptors were also not affected by exposure to the combined electric 3 kVm rms and magnetic 48 uT rms components of this Loran-C Type waveform. Behavioral studies compared the rats known ability to detect low intensity 60 Hz electric fields 10 KVm with potential detection of Loran-like fields. The data showed that rats trained in an operant conditioning task did not reliably detect the 100 KHz at any field strength used 0 to 9 kVm. Biochemical studies measured ornithine decarboxylase ODC activity in tissue culture cells to monitor membrane signal transduction. Exposure to the Loran-C type waveform at 10mVcm field strength did not modify basal ODC activity in primary bone cells from mouse calvaria.
