View Original AbstractThis study found no immediate cellular damage response to cell phone-level microwave radiation, but examined only one biomarker over 48 hours.
Plain English Summary
Researchers exposed human cells to 837 MHz microwave radiation (the frequency used by early cell phones) for 2 hours at power levels ranging from 0.9 to 9.0 W/kg. They measured levels of TP53, a critical protein that normally increases when cells are damaged and helps prevent cancer formation. The study found no changes in TP53 levels up to 48 hours after exposure, suggesting these microwave frequencies did not trigger the cellular damage response.
Study Details
To evaluate the safety of cellular telephones, TP53 responses in human fibroblast cells were studied after exposure to 837 MHz microwaves.
Cells were exposed in a temperature-controlled transverse electromagnetic (TEM) chamber to a specifi...
No morphological alterations were observed in microwave-treated cells compared to sham-treated cells...
We conclude that TP53 protein expression levels in cultured human fibroblast cells do not change significantly during a 48-h period after exposure to 837 MHz continuous microwaves for 2 h at SAR levels of 0.9 or 9.0 W/kg.
