Plain English Summary
Researchers exposed human immune cells to cell phone radiation (1.8 GHz) combined with a chemotherapy drug (doxorubicin) to see how radiation affects DNA repair. They found that while the radiation alone didn't damage DNA, it significantly interfered with the cells' ability to repair DNA damage caused by the chemotherapy drug. This suggests that cell phone radiation may impair the body's natural DNA repair mechanisms when cells are already stressed.
Why This Matters
This study reveals a concerning interaction between radiofrequency radiation and DNA repair that goes beyond simple damage assessment. The researchers used a SAR level of 2 W/kg, which is at the current regulatory limit for cell phones in many countries. What's particularly troubling is that the radiation didn't need to cause DNA damage directly to create problems - it interfered with the cells' natural repair processes when they were already challenged by a toxic substance. This finding suggests that EMF exposure may be most harmful when our bodies are already under stress from other sources like illness, medication, or environmental toxins. The implications extend beyond cancer treatment to everyday scenarios where our cells face various stressors while we're simultaneously exposed to wireless radiation from phones, WiFi, and other devices.
