900 MHz electromagnetische velden beinvloeden neuronen op non-thermische manier

Een onderzoek uit China toont aan dat electromagnetische straling met een frequentie van 900 MHz invloed heeft op de neuronen van ratten. De kans op toevalligheden is kleiner dan 1%. Tevens is gevonden dat een hogere intensiteit meer invloed heeft. De gevonden effecten moeten geclassificeerd worden als niet-thermische biologische effecten.

OBJECTIVE: To study the effect of 900MHz low intensity microwave electromagnetic fields (EMF) on AMPA GluR2 and the concentration of intracellular calcium in postnatal rat cerebral cortical neurons. METHODS: Neurons were exposed to low intensity 900MHz continuous microwaves EMF (SAR = 3.22W/kg, 2.23W/kg, 1.15W/kg) for 2 hours per day in 4 or 6 consecutive days and for 12 hours at a time (SAR = 3.22W/kg). Such exposures were carried out to have knowledge of the effect of microwave on protein of GluR2 and intracellular calcium ions. RESULTS: The results of immunochemistry and laser confocal scan showed that compared with sham, protein of GluR2 of exposed neurons were significantly down-regulated (P < 0.01), while intracellular calcium ions were significantly up-regulated (P < 0.01). CONCLUSION: The microwaves play a role of accumulation in the effect on exposed neurons, the trends in dose response relationship were found between the exposure intensity and the effects, effect of the microwave on exposed neurons should be classified as athermal effects of EMF.
