Microwave/RF radiation has been implicated as a potential cause of increased autism in children through increased oxidative stress and the activation of voltage-gated calcium channels [1]. The Hollywood area of Northern Los Angeles has been identified as a persistent autism cluster in children by Columbia University researchers, with over 400% higher rates in Northern Los Angeles than other areas of California [2]. The Hollywood autism cluster area also has over 224 high gain microwave broadcast antennas, which is over 400% higher density of microwave radiation than other areas of California.  [3]
