Positive and negative controls were included in each set of experiments. Negative controls were cultured in the incubator for as long as the corresponding exposure, slides of positive controls immersed in ice-cold phosphate-buffered saline were irradiated for 3 min using UV light (254 nm, 800 µW/cm²).
The exposure system showed an SAR non-uniformity for monolayer cell cultures of less than 26% and a temperature load of less than 0.03 °C per W/kg. The temperature difference between the waveguides did not exceed 0.1 °C. For further details and dosimetry see Schuderer J (2005) EMF risk assessment: ''in vitro'' research and sleep studies.
