|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.|
No parameters are specified for this exposure.
