Four groups of fertilizedeggs were examined (n=10-12 per group): 1.) control group, 38 h brooding, 2.) exposed during 38 h brooding, 3.) control group, 120 h at room temperature, then 38 h brooding (158 h in total) and 4.) exposed during 120 h at room temperature, then during 38 h brooding (158 h in total). Brooding took place in incubators (38°C). Control groups and exposure groups were brooded at the same time, however the control eggs were shielded against the electromagnetic fields by 6 layers of aluminium foil.
laboratory incubator (metal covers from the door and the sides removed and replaced by plastic covers); temperature 38.3±0.2°C, relative humidity 60%
Setup
eggs placed on horizontal trays; cell phone positioned on a plastic stand inside the incubator at a distance of 3 cm from the eggs; unexposed eggs placed inside the same incubator at a distance of 10 cm from the exposedeggs and shielded by 6 layer of an aluminum foil (each foil was 0.03 mm thick); cell phone kept in connecting mode by auto-redial; each connecting attempt lasted 48 s; distance between the phone and the eggs: 3 cm - 10 cm
