Public schools have a WiFi router in the center of each classroom, usually fixed to the ceiling, and it is on 24/7. The teacher and the 20-28 students (avg.) per day assigned to each classroom are within 4-18 feet of this WiFi router for 6-7 hours each day (approx.) Please consider the health and behavioral affects this may have on those assigned to a classroom. Additionally, smart boards for teaching and learning. Guidelines on proximity and duration to protect the teacher and student populations is requested. Each student is assigned a computer and each teacher has 1-2 computers, which are on or charging in the classroom all day. What is the cumulative affect and total exposure to the potentially harmful EMFs that all of these devices in sum total emit to each person? What should the daily limit for each student/teacher/worker/human be? Shouldn't a sum total daily limit for human consumption include close proximity to above ground electric transmission towers? Estimation: approx. 3.8 million public school teachers, 49 million students, and millions of other citizens who are working in public schools. Request to examine physical health affects, daily limits, ways to mitigate, and behavioral and mental health affects.
