Which body organ is the most likely to be damaged from the heating effects of RF radiation?
- A Liver
- B Hands
- C Eyes

Radio frequency energy can heat body tissues, and the eyes are especially vulnerable because they lack blood vessels to carry away that heat, potentially causing cataracts. The full explanation — and one for every question — is in Pro.
