|Pulse width||83 µs|
|Repetition frequency||120 Hz|
|Chamber||The exposure facility has previously been described in detail [Harrison et al., 1985].|
|Setup||Three 25-cm² cell-culture flasks filled with medium were placed horizontally and cell-side down beneath a quarter-wave transformer covering the central 25 x 25 cm region of a large (60 x 60 x 12 cm) constant-temperature (37.2 ± 0.1°C) water bath with their cellular attachment plane approx. 3 cm below water level. Two flasks for sham exposure were placed inside a grounded copper-mesh enclosure located at the bottom, peripheral to the central region.|
|Sham exposure||A sham exposure was conducted.|
|Additional info||Cells were exposed to MW only, or they were pre- or post-irradiated with 1.5 Gy of 238-kVp X rays. Additional groups were sham exposed or exposed to X rays only. It is not really clear from the article whether or when the latter group was also sham exposed.|
A statistically significant enhancement of transformation response by TPA in cells exposed to 2.45 GHz microwaves is shown. Microwaves alone had no effect on cell transformation. Plating efficiency and cell survival were not affected by TPA or microwaves.
