Cell phone radiation at 847.74 MHz showed no direct DNA damage in blood cells at high exposure levels over 24 hours.

Plain English Summary

Summary written for general audiences

Researchers exposed human blood cells to cell phone radiation at 847.74 MHz for 24 hours to see if it would damage DNA or cause chromosome breaks. They found no significant genetic damage compared to unexposed cells, even at high exposure levels (4.9-5.5 W/kg SAR). This suggests that this particular frequency and exposure duration may not directly harm cellular DNA.

Study Details

The aim of this study is to investigate Chromosome damage and micronucleus formation in human blood lymphocytes exposed in vitro to radiofrequency radiation at a cellular telephone frequency (847.74 MHz, CDMA).

Peripheral blood samples collected from four healthy nonsmoking human volunteers were diluted with t...

The data indicated no significant differences between RF-radiation-exposed and sham-exposed lymphocy...

Thus there was no evidence for induction of chromosome aberrations and micronuclei in human blood lymphocytes exposed in vitro for 24 h to 847.74 MHz RF radiation (CDMA) at SARs of 4.9 or 5.5 W/kg.

Quick Questions About This Study

No, a 2001 study found no chromosome damage in human blood lymphocytes exposed to 847.74 MHz CDMA radiation for 24 hours. Even at high exposure levels (4.9-5.5 W/kg SAR), researchers detected no significant genetic damage compared to unexposed cells.
Research shows 24-hour exposure to 847.74 MHz CDMA radiation does not damage DNA in human blood cells. The study found no significant differences in chromosome aberrations or micronuclei formation between exposed and unexposed lymphocytes at SAR levels up to 5.5 W/kg.
Based on laboratory testing, 847.74 MHz radiation appears safe for human lymphocytes at the levels tested. Researchers found no evidence of chromosome damage or micronuclei formation in blood cells exposed for 24 hours at SAR levels of 4.9-5.5 W/kg.
Scientists tested CDMA radiation at SAR levels of 4.9 and 5.5 W/kg in human blood lymphocytes. These high exposure levels, maintained for 24 hours at 847.74 MHz, produced no significant chromosome damage or genetic abnormalities compared to control cells.
No, human blood lymphocytes exposed to 847.74 MHz CDMA radiation for 24 hours showed no increase in micronuclei formation. The 2001 study found no significant differences in cellular damage markers between RF-exposed and unexposed cells at tested SAR levels.
