Two power densities were tested at each of three ambient temperatures (24, 28, and 31°C).
|Distance between exposed object and exposure source||102 cm|
|Chamber||The anechoic chamber was 2.44 x 2.44 x 3.05 m. A small climate-conditioned cubicle was created by a 5-cm thick Styrofoam partition. The dipole antenna was mounted in a 90° aluminium corner reflector.|
|Setup||Subjects wearing a bathing suit sat in a light plastic chair with their back towards the antenna. The electric field vector of the incident plane wave was aligned with the long axis of the subject's body (E-polarization).|
|Sham exposure||A sham exposure was conducted.|
|Additional info||After 30 min of equilibration to the prevailing temperature (24, 28, or 31 °C), the subjects were exposed or sham exposed for 45 min.|
No changes in metabolic heat production occurred under any irradiation conditions. Vigorous increases in sweating rate on back and chest, directly related to both ambient temperature and power densities, cooled the skin and ensured efficient regulation of the deep body temperature to within 0.1°C of the normal level.
