Plain English Summary
Researchers exposed human brain and lung cells to radiofrequency radiation at 2.14 GHz (similar to cell tower frequencies) for up to 48 hours to see if it would trigger cell death or DNA damage responses. They tested exposure levels from 0.08 to 0.8 watts per kilogram - with the lowest level matching international safety limits for public exposure. The study found no evidence that this RF radiation caused cells to die, damaged DNA, or activated stress response pathways even at levels 10 times higher than safety guidelines.
Study Details
A large-scale in vitro study focusing on low-level radiofrequency (RF) fields from mobile radio base stations employing the International Mobile Telecommunication 2000 (IMT-2000) cellular system was conducted to test the hypothesis that modulated RF fields induce apoptosis or other cellular stress response that activate p53 or the p53-signaling pathway.
First, we evaluated the response of human cells to microwave exposure at a specific absorption rate ...
Under the RF field exposure conditions described above, no significant differences in the percentage...
Our results confirm that exposure to low-level RF signals up to 800 mW/kg does not induce p53-dependent apoptosis, DNA damage, or other stress response in human cells.
