FCC exposure limits (1996, based on thermal effects only) are significantly less conservative than ICNIRP 2020 or EU recommendations. WiFi router RF power is typically 100 mW-1W — orders of magnitude below FCC limits at normal distances. 5G millimeter wave has very short range and does not penetrate walls, but small cell proximity (utility poles) is closer to residences.","synthesis":{"derived_risk_level":"high","synthesis_confidence":0.703,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":1.4,"vulnerability_escalated":true,"escalation_reason":"Child exposure group","compounds_resolved":1,"compounds_total":1,"synthesis_date":"2026-05-09","synthesis_version":"1.2.0","methodology_note":"exposure_modifier and adjusted_magnitude are computed from ALETHEIA-calibrated heuristics (route × duration × frequency multipliers, clamped to [0.5, 1.4]).
