ID Number		1009
Study Type		In Vivo
Model		260, 915, 2450 MHz (CW) exposure to hens and analysis of egg laying
Details		Hens (in metal cages) were exposed to 260 MHz (CW at 100 mW/cm2), 915 MHz (CW at 800 mW/cm2), 2450 MHz (CW at 800 mW/cm2), or 60 Hz (1600 V/m or 1.4G). Hens exposed to all fields except 915 MHz laid less eggs (~15% less than controls). Hatch rate of fertile and total eggs was not significantly influenced by exposure to any of the five fields. A lower incidence of male chicks was noted in the ELF magnetic field treatment (32.3%). No macroscopic abnormalities attributable to treatments were noted in the chicks hatched or in the dead embryos.

Comments		Hen were exposed in metal cages, raising many dosimetry questions and suggesting possible hot spots and field perturbations.
