| Summary: | In this paper we describe the design of an exposure setup used to
study possible non-thermal effects due to the exposure of human hematopoietic
stem cells to GSM, UMTS and LTE mobile communication signals. The experiments
are performed under fully blinded conditions in a TEM waveguide located
inside an incubator to achieve defined environmental conditions as required
for the living cells. Chamber slides containing the cells in culture medium
are placed on the septum of the waveguide. The environmental and exposure
parameters such as signal power, temperatures, relative humidity and CO<sub>2</sub>
content of the surrounding atmosphere are monitored permanently during the
exposure experiment. The power of the exposure signals required to achieve
specific absorption rates of 0.5, 1, 2 and 4 W kg<sup>−1</sup> are
determined by numerical calculation of the field distribution inside the cell
culture medium at 900 MHz (GSM), 1950 MHz (UMTS) and 2535 MHz (LTE). The
dosimetry is verified both with scattering parameter measurements on the
waveguide with and without containers filled with cell culture medium and
with temperature measurements with non-metallic probes in separate heating
experiments. |
