Research on environmental EMF sources - cell towers, 5G small cells, power lines, and smart meters.
## Outdoor / Infrastructure EMF Sources When you step outside your home, you enter an environment where electromagnetic fields come from sources beyond your direct control. Cell towers broadcasting 24/7, power lines carrying electricity to neighborhoods, smart meters collecting usage data, and increasingly, 5G small cells mounted on streetlights and utility poles. These infrastructure sources share a common characteristic: they're part of the built environment around us, installed and operated by utilities and telecommunications companies to serve entire communities.

Scientists exposed purified DNA to microwave radiation between 2.00 to 8.75 GHz at non-thermal power levels and found it caused both single and double strand breaks in the genetic material. The damage required the presence of small amounts of copper and increased with both microwave power and exposure duration. This demonstrates that microwave radiation can directly damage DNA even without heating effects.
