This confidential FCC document reveals internal testing that found multiple cell phones exceeded official SAR (radiation absorption) limits when tested at 2mm separation distance. The testing appears to have been conducted on portable handsets to evaluate compliance with federal safety standards. This suggests the FCC was aware that phones could exceed their own safety limits under certain testing conditions.
