Study Type		In Vivo
Model		915 MHz (CW, AM-16 Hz, GSM), 1.2 GHz (CW, PW) exposure to rats and analysis of blood brain barrier permeability
Details		Sprague Dawley rats were exposed to 1.2 GHz (CW & PW- pulse repetition rate of 1000 pulses/sec, pulse width of 0.5 msec) microwaves for 30 minutes at power densities of up to 75 mW/cm2. No transfer of fluorisein dye or radiolabeled mannitol or seretonin was observed following exposure unless rats were made hyperthermic, indicating no non-thermal effects on blood brain permeability. In a related study and replication attempt of Salford and Persson, Fisher 344 rats were exposed to 915 MHz (CW, AM-16 Hz, GSM) RF at SARs of 0.002, 0.02, 0.2, 2, and 20 W/kg for 30 minutes/day for 3 days in a TEM cell and analyzed for changes in blood brain barrier permeability. Other animals were exposed to 217 MHz at 0.0025, 0.025, 0.25, and 2.5 W/kg. Analysis of stress hormone levels showed no significant stress effects of the restraint device used for exposure. The authors report no detectable albumin leakage in any exposed groups (although permeability did increase with non-RF temperature treatment)
