Effects of Low-Level Electric and Magnetic Fields on the Growth of Animals
Depressions in growth rate were observed in chicks continuously exposed to the following signals up to 28 days of age: (1) the near field of a UHF signal at 880 MHz, with a calculated average power density of 33 μW/cm 2 ; (2) the near field of a VHF signal at 260 MHz, with a calculated average power...

Summary: | Depressions in growth rate were observed in chicks continuously exposed to the following signals up to 28 days of age: (1) the near field of a UHF signal at 880 MHz, with a calculated average power density of 33 μW/cm 2 ; (2) the near field of a VHF signal at 260 MHz, with a calculated average power density of 33 μW/cm 2 ; (3) a low frequency electric field at either 45 or 60 Hz with calculated electric fields of 36 and 34 V/cm, respectively; and (4) a low frequency magnetic field at either 45 or 60 Hz with 1.4 and 1.2 G measured values of magnetic fields. No significant differences in feed utilization between control chicks and chicks exposed to the UHF and VHF signals were noted. Feed utilization between control chicks and chicks exposed to the electric and the magnetic fields was different and varied depending upon the experiment. |
