||In order to test the generality of radiofrequency-radiation-induced change in alteration of (45)Ca(2+) efflux from avian and feline brain tissues, human neuroblastoma cells were exposed to electromagnetic radiation at 147 MHz, amplitude modulated (AM) at 16 Hz, at specific absorption rates (SAR) of 0.1, 0.05, 0.01, 0.005, 0.001, and 0.0005 W/kg. Significant (45)Ca(2+) efflux was obtained at SAR values of 0.05 and 0.005 W/kg. Enhanced efflux at 0.05 W/kg peaked at the 13-to-16 Hz and at the 57.5-to-60 Hz modulation ranges. A Chinese hamster-mouse hybrid neuroblastoma was also shown to exhibit enhanced radiation-induced (45)Ca(2+) efflux at an SAR of 0.05 W/kg, using 147 MHz, AM at 16 Hz. These results confirm that amplitude-modulated radiofrequency radiation can induce responses in cells of nervous tissue origin from widely different animal species including humans. The results are also consistent with the reports of similar findings in avian and feline brain tissue reported by others and indicate the general nature of the phenomenon. (Copyright (c) 1989 Alan R.
