|Distance between exposed object and exposure source||5 cm|
|Setup||Blood samples were placed in a cooled box at 17 ± 1 °C at 5 cm from the antenna of an analogue car phone.|
|Additional info||The following kinds of exposure were investigated: MW or MMC or X-ray exposure alone, MW exposure followed by MMC, and MW exposure followed by X-rays. MW and X-ray (5 doses) exposures preceded cell cultivation. MMC (2 doses) was present during all 72 h of cell cultivation. Control samples were kept in the same conditions of temperature and humidity as the exposed ones. X-ray exposed blood samples were irradiated at room temperature with doses of 5, 10, 20, 30 or 100 cGy at a dose rate of 1 Gy/min.|
In the present investigation it was not possible to demonstrate any effect of 455.7 MHz electromagnetic fields on the genetic material of white blood cells in vitro. The data do not support the hypothesis that radiofrequency fields act synergistically with chemical (in this case Mitomycin C) or physical (e.g. X-rays) mutagens.
