“It just seems like coincidence is no longer a reason for all this illness”: four students at California’s Weston Elementary have been diagnosed with cancer in the last three years, and San Joaquin County parents are now convinced the cause is a cell phone tower located in its schoolyard. While the district’s tests have shown “the tower is safe and meets federal regulations,” many are fighting to get it removed. “I wouldn’t send my kids there at all, it absolutely is dangerous,” said Eric Windheim, an electromagnetic radiation specialist. “Children are still developing and their cells are still being divided. It’s the worst possible time in their life to be exposed.” He says it’s not just a cell tower, it also transmits wireless frequencies. “Instead of only going 300 yards like regular Wi-Fi, Y-Max can go 30 miles,” he said.
