The frequencies emitted by the cell towers was between 900MHz and 1800MHz. The RF exposure level for the exposed group was in the range of 2.80–7.52 mW/m2, well under the FCC limit of 10,000 mW/m2.  The RF exposure level for the control group was 0.014–0.065 mW/m2, which is at least 100 times lower than the exposure level in the exposed group.
