Time of investigation:
  • after exposure

Main outcome of study (acc. to author)

No direct cytogenetic effect was found. The combined exposure of the cells to the radiofrequency fields followed by their cultivation in the present of mitomycin C revealed a very weak effect when compared to cells exposed to mitomycin alone.
