See the Radiation Emissions Report (survey 2/4/2015) on Green Valley Academy PGCPS School that shows that some of the highest radiation readings were at the playground and near the cell tower.
The Green Valley Academy cell tower maximum radiation was at .040 % FCC limit which means the maximum radiation level was at .40 W/cm2.
This means, the Green Valley Academy cell tower is resulting in about 4 times the radiation allowed at Los Angeles Public Schools as they use a radiation limit at 10,000 times less than the FCC.
Some of the highest radiation readings were at the playground.
