To investigate the influences of underground water on normal adults, serial measurements of blood pressure(BP), pulse rate(PR), electrocardiogram(EKG), transcranial doppler sonography(TCD), quantitative electroencephalogram(QEEG), visual evoked potential(VEP), and cognitive evoked potential by auditory stimulation(P300) were performed on thirty one normal healthy adults before and after exposure for one hour to the zone of harmful radiation in underground water.
The results were as follows ;
1) There were no significant differences in BP, PR, results of EKG, and QEEG in comparison of before and after exposure to the zone of harmful radiation in underground water.
2)There were no significant differences in mean blood flow velocity, resistance index, and pulsatility index by TCD in comparison of before and after exposure to the zone of harmful radiation in underground water
3) The VEP study revealed no significant change in P100 latency(p>005) but there was significant decrease in amplitude in comparison of before and after exposure to the zone of harmful radiation in underground water.
4) The P300 study revealed no significant change in P300 latency(P>0.05) but there was significant decrease in amplitude in comparison of before and after exposure to the zone of harmful radiation in underground water.
In conclusion, despite its unidentified underlying mechanism, radiationin underground water may influence inhibitory effects of perception by the brain and the heurophysiological pathway of vision.
