Abstract
It has been shown that rats, given the choice, will spend more time out of a 60‐Hz electric field than in it at field strengths ⩾ 75 kV/m. This paper describes research to examine the relevance of these data to a different species, the pig. Miniature pigs that had been exposed to a 60‐Hz electric field at 30 kV/m for 20 h/day, 7 days/week for as long as 6 months, were tested for their preference for the presence or absence of the field during a 23.5‐h period. Similar to earlier results with rats, miniature pigs spent more time out of the electric field than in it during the sleeping period.
