View Original AbstractDaily cell phone frequency exposure tripled genetic damage markers in rat bone marrow, suggesting RF radiation may harm blood-forming cells.
Plain English Summary
Researchers exposed rats to 910-MHz radiofrequency radiation (similar to cell phone frequencies) for 2 hours daily over 30 days and examined their bone marrow for genetic damage. They found a nearly threefold increase in micronuclei, which are markers of DNA damage and chromosome breaks, in the exposed animals compared to controls. This suggests that prolonged RF exposure at cell phone frequencies may cause genetic damage in blood-forming cells.
Why This Matters
This study adds to the growing body of evidence that radiofrequency radiation can cause genetic damage at the cellular level. The 910-MHz frequency tested falls squarely within the range used by mobile phones and wireless devices, making these findings directly relevant to human exposure. What makes this research particularly significant is that it examined bone marrow, where blood cells are produced. Genetic damage in these cells could potentially affect the entire circulatory and immune systems. The researchers found that male rats showed greater sensitivity than females, which aligns with other studies suggesting sex-based differences in EMF susceptibility. While the specific power levels weren't reported, the consistent daily exposure pattern mirrors how we actually use wireless devices. The science demonstrates that RF radiation isn't as biologically inert as regulatory agencies assume.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 910-MHz Duration: 2 h over a period of 30 consecutive days
Study Details
Aiming to investigate the possibility of electromagnetic fields (EMF) developed by nonionizing radiation to be a noxious agent capable of inducing genotoxicity to humans, in the current study we have investigated the effect of 910-MHz EMF in rat bone marrow.
Rats were exposed daily for 2 h over a period of 30 consecutive days. Studying bone marrow smears fr...

The results indicate that 910-MHz EMF could be considered as a noxious agent capable of producing genotoxic effects.
