It is a plain old 4G tower. I bet these same parents have WiFi and use BlueTooth... for goodness sake, this is a grieving parent grasping at straws. I feel for them, I would be very upset if my kids came down with cancer... but I would be demanding tests of the air and water in and around the school; What building materials are being used? What is in the water? These are things that are far more likely to cause cancer. As an asside; I use to work in a school district, and the community got up in arms when a new cell tower went up in view of the school. Students, faculty, parents were all sorts of suspicious of the new tower for about a year before they cooled off. But my favorite thing to do was to take them to the other side of the building, and show them the 5 year old cell tower that was literally within 600 feet from the school grounds. The new tower was about a mile and a half away.... *sigh* people. Still, lets not give an irrational grieving parent a microphone. This is not productive.
