Researchers have found that trees exposed to radiofrequency radiation from phone masts begin to show visible signs of harm. When radiation levels rise above 50 microwatts per square meter, the side of the tree facing the mast often develops dying branches and leaves that lose their natural color. The effect is clear enough to be noticed without special equipment.
In a study published in Science of the Total Environment, scientists documented 60 trees showing signs of damage, while trees in areas with lower radiation exposure remained healthy. This sharp contrast highlights how location and exposure play a critical role in a tree’s survival. The stress caused by radiation does not simply remain localized but worsens with time.
As the exposure continues, the damage spreads outward from the affected side until the entire crown of the tree is compromised. The findings suggest that even relatively low levels of electromagnetic radiation can slowly but steadily harm natural ecosystems. Trees, which are essential for clean air, shade, and biodiversity, may be more vulnerable than once believed.
