==== - High-voltage transmission lines (typically 345 kV to 765 kV, like Oncor's Bell County East line) emit low-frequency electromagnetic fields. ====
* Most health agencies (e.g., WHO, CDC) do not confirm causality between EMF exposure and cancer, but they acknowledge a potential association with childhood leukemia at chronic exposure above 0.3–0.4 µT (3–4 mG).

➤ At 150 feet, you could still be exposed to 10–20 mG, which is higher than ambient levels.

🧠 Interpretation: While not legally unsafe, many researchers and health-conscious planners recommend a minimum of 300–500 feet from major transmission lines for long-term residential exposure, especially for families with young children.
