研究目的(著者による)

To study cytogenetic effects in peripheral blood lymphocytes from 49 subjects who were professionally exposed to mobile phone electromagnetic fields (radio field engineers and other subjects working for two of the Belgian mobile phone operators).

詳細情報

Subjects' blood cells were also exposed to mutagen mitomycin C in order to investigate possible combined effects of radiofrequency irradiation and the chemical.
The data were compared to those obtained in 25 unexposed control subjects.

研究の主なアウトカム(著者による)

The comet assay, sister chromatid exchange and chromosome aberration tests revealed no evidence of radiofrequency-induced genetic effects.
No cooperative action was found between the electromagnetic field exposure of blood cells and the mutagen using either the comet assay or sister chromatid exchange test.
