This study was designed to examine whether the exposure to 800 MHz electromagnetic field affects the number of chromosomes in human peripheral blood lymphocytes in vitro.
The human peripheral blood lymphocytes were obtained from 14 healthy male donors (23 to 39 years old). After exposure for 72 hours at two different specific absorption rates (2.9 and 4.1 W/kg) the chromosomes 1, 10, 11, and 17 were further investigated. Additionally, the effects of the temperature on the number of these chromosomes were determined in four samples incubated at 33.5, 37, 38.5, 40 °C.

Increased levels of aneuploidy depending on the chromosome studied as well as on the level of exposure were found. In chromosomes 1 and 10, there was increased aneuploidy at the higher specific absorption rate of 4.1 W/kg, while for chromosomes 11 and 17, the increases were observed only for the lower specific absorption rate of 2.9 W/kg.
No statistically significant effect of temperature on the level of aneuploidy was observed over the range of 33.5-40 °C compared to 37 °C.
These results suggest the possible existence of an athermal effect of radio frequency irradiation that causes increased levels of aneuploidy.
