Abstand zw. exponiertem Objekt und Expositionsquelle
The exposure system has been described and illustrated in a previous publication [Zook and Simmens, 2001]. To reduce distortion, the exposure devices were composed entirely of Plexiglas and were located on plastic racks so that no metal or cinderblock walls were within 39 cm of the antenna.
Rats were placed in well ventilated Plexiglas tubes positioned radially in a carousel exposure system with the central dipole antenna at 2.0 ± 0.5 cm directly in front of each rat's nose (5.0 ± 0.7 cm from the middle of the rat's brain). Removed animals were replaced by cone-shaped plastic tubes filled with a substance having dielectric properties similar to flesh.
SAR was determined numerically by FDTD modelling and verified experimentally by linear extrapolation from the rate of temperature rise in sagittal sections of eight rat cadavers exposed at high RF power levels.
