A cow with abnormal behavior normalized completely within five days after being moved 20 km from a transmitting antenna, but symptoms returned when the cow was brought back.

Plain English Summary

Summary written for general audiences

Researchers observed behavioral abnormalities, reduced milk yield, and increased health problems in a herd of cows near a TV and cell phone transmitting antenna over two years. Evaluation of possible factors found no explanation other than high-frequency electromagnetic fields. In an experiment, a cow with abnormal behavior was moved 20 km from the antenna and normalized completely within five days, but symptoms returned when the cow was brought back. The researchers suggested the abnormalities might be related to electromagnetic field exposure, with power densities measured at 0.02-7 mW/m2.

Why This Matters

The study aimed to investigate extraordinary behavior disorders in cows near transmission stations. Power densities at the site were measured between 0.02 and 7 mW/m2.

In view of the previous described effects of electromagnetic fields, it might be possible that the observed abnormalities in cows are related to electromagnetic field exposure. (power densities measured 0.02-7 mW/m2).
