Leukocytes from four young healthy donors were intermittently exposed to radiofrequency for 24 h, and then irradiated with X-rays at doses of 0.25, 0.5, 1.0 and 2.0 Gy. DNA damage was detected at 0, 15, 45, 90, 150 and 240 min after exposure to X-rays.
|Exposure duration||5 min on - 10 min off, for 24 hr|

The data showed that the DNA repair speeds of human leukocytes after X-ray exposure exhibited individual differences among the four donors. Additionally, the intermittent exposures of 1.8 GHz radiofrequency for 24 h did not directly induce a DNA damage or exhibit synergistic effects with X-rays on human leukocytes.
