Vier Gruppen an befruchteten Eiern wurden untersucht (n=10-12 pro Gruppe): 1.) Kontrollgruppe, 38 Stunden Bebrütung, 2.) Exposition während 38 h Bebrütung, 3.) Kontrollgruppe, 120 Stunden bei Raumtemperatur, dann 38 Stunden Bebrütung (gesamt 158 Stunden) und 4.) Exposition während 120 Stunden Raumtemperatur, dann während 38 Stunden Bebrütung (gesamt 158 Stunden). Die Bebrütung fand in Inkubatoren (38°C) statt. Die Kontrollgruppen und die Expositions-Gruppen wurden zeitgleich bebrütet, allerdings waren die Kontroll-Eier in 6 Lagen Aluminiumfolie eingewickelt, um die Felder abzuschirmen.
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%
Aufbau
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 exposed eggs 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
