Model		1.25 GHz (CW) exposure to chicken eggs and analysis of energy absorption and temperature
Details		A total of 550 fertile chicken eggs (White Leghorn) were exposed to 1.25 (CW) fields at 6 different ranging from 0.75-9.0 mW/cm2. The eggs were exposed either continuously throughout the whole 21 days of incubation or in a short-term exposure of 1-2 h/d. The temperatures of the embryonic tissue and the amniotic fluid were measured with inserted temperature probes. During RF exposure, the temperature in the eggs increased from 0.25 C at 1.25 mW/cm2 (1.45 W/kg) to 2.3 C at 9 mW/cm2 (10.44 W/kg). The temperature of the exposed tissue and amniotic fluid reached its maximum approximately 40-50 min after the RF field was energized.
