Main outcome of study (acc. to author)

In comparison to the control cell samples, the growth curve of the 864 MHz exposed cells showed a significant decrease after 2 h and 3 h exposure on day 3 after exposure. Likewise, cells exposed to 935 MHz microwaves for 3 h showed a significant growth decrease on day 3 after exposure.
The colony-forming ability and cell viability of cells exposed to 864 MHz and 935 MHz microwaves did not significantly differ from the controls. The applied radiofrequency/microwave fields showed a similar effect on cell culture growth, colony-forming ability and viability of V79 cells.
