Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Subjects will be exposed with signals from mobile communication handheld devices for 7.5 h during the night and for the whole duration of the test session during the day. Exposures will be GSM (900 MHz), TETRA (400 MHz) and sham. Each subject is exposed with each exposure three times in addition to an adaptation/screening night and day to learn the test.
The results have to be discussed in the context of possible health risks resulting from RF-EMF exposure.
