Exposure setup
Exposure source
Setup The phone supported by a metal stand in the normal use position was pressed against the subject's left ear with the aerial extended away from the head.
Additional info Subjects participated in three exposure sessions, at 1-h intervals, of 15 or 30 min duration: 1) Continuous exposure to "silent energy" for 30 min. No telephone conversation. 2) Intermittent exposure for 30 min. Subjects made 12 telephone conversations of 2 min and 30 s each. 3) Continuous exposure "to the same EMF" for 15 min. The phone was held in contact with the left retroauricular mastoid area rather than the ear.
