研究目的(著者による)

To study the effects of radiofrequency irradiation applied alone or in combination with x-rays on genotoxicity in vitro in human lymphocytes. Combined exposures were used to examine whether radiofrequency irradiation might act epigenetically by reducing the fidelity of DNA repair of DNA damage caused by a well-characterized and established mutagen.

詳細情報

1-min x-rays exposure (1.0 Gy) was given immediately before or after the radiofrequency irradiation.
The experiments were performed in two different laboratories (in Italy and UK).

General information

Blood samples were exposed at two SAR values, alone or combined with a 1-min exposure to 1.0 Gy of 250 kVp X-rays given immediately before or after the RF exposure.

研究の主なアウトカム(著者による)

No effect of radiofrequency irradiation alone could be observed for any of the endpoints. In addition, radiofrequency exposure did not modify any measured effects of the x-radiation.
Within the experimental parameters of the study no genotoxic or epigenetic effects from the radiofrequency signal was found.
