Plain English Summary
Researchers exposed blood samples from six healthy men to radio frequency signals from CDMA mobile phones for one hour, then tested for DNA damage using a technique called the comet assay. They found that while RF exposure alone didn't cause significant DNA damage, it did enhance DNA breaks when combined with a chemical that interferes with DNA repair. This suggests that mobile phone radiation may cause DNA damage that cells can normally repair, but problems could arise when repair mechanisms are compromised.
Why This Matters
This study reveals a concerning pattern we see repeatedly in EMF research: RF radiation from mobile phones can cause DNA damage, even when that damage appears repairable under normal conditions. The researchers used aphidicolin (APC), a chemical that blocks DNA repair, to reveal damage that would otherwise be masked by the cell's natural repair processes. What this means for you is that your cells may be working overtime to repair RF-induced DNA damage from your phone use. While healthy cells can typically handle this repair burden, the concern is what happens when your cellular repair systems are compromised by age, illness, stress, or other environmental toxins. The science demonstrates that RF exposure isn't as benign as the wireless industry claims, even at the cellular level where damage may be occurring and getting repaired without your knowledge.
Exposure Information
Specific exposure levels were not quantified in this study. Duration: 1 and 2 hours
Study Details
The aim of present study is to assess DNA integrity on the effect of exposure to a radio frequency (RF) signal from Code Division Multiple Access (CDMA) mobile phones.
Whole blood samples from six healthy male individuals were exposed for RF signals from a CDMA mobile...
The RF signals and APC (0.2 microg/ml) alone or in synergism did not have any significant DNA damage...
From these results, it appears that the repair inhibitor APC enhances DNA breaks at 2 microg/ml concentration and that the damage is possibly repairable. Thus, it can be inferred that the in vitro exposure to RF signals induces reversible DNA damage in synergism with APC.
