EMF at the pad surface is significant but drops to background within 10-20 cm. Generates more heat than wired charging (30-40% energy lost as heat). Foreign metal objects (coins, keys, paperclips) on pad heat dangerously — Foreign Object Detection (FOD) mandated in Qi v1.3. Nightstand placement puts pad near sleeping head — EMF concern is theoretical at Qi power levels.","synthesis":{"derived_risk_level":"moderate","synthesis_confidence":0.703,"synthesis_method":"compound_composition","context_used":"human_adult","context_source":"product_users","exposure_modifier":1.15,"vulnerability_escalated":false,"escalation_reason":null,"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]).
