Study type: Medical/biological study (experimental study)

Non-ionizing electromagnetic radiations, emitted by a cellular phone, modify cutaneous blood flow. med./bio.

Published in: Dermatology 2003; 207 (1): 10-14

Aim of study (acc. to author)

The aim of the study was to verify whether electromagnetic radiation (EMR) emitted by cellular phone could affect the cutaneous blood flow in ear skin.

Exposure 1

Main characteristics
Frequency 300 MHz–300 GHz
Type
Exposure duration 6 phases of 4 min each, see add. information
Additional info Measurements were made with a GSM mobile phone. The indicated frequency range is therefore misleading.
Modulation
Modulation type pulsed
Exposure setup
Exposure source
Distance between exposed object and exposure source 0 cm
Setup A hole was created in the mobile phone next to the aerial to allow the passage of the optical fibre probe. The mobile phone was kept in contact with the skin of the ear of the volunteers.
Additional info Measurements were performed in 6 phases of 4 min each (no breaks between) with the mobile phone in the following conditions: removed, turned off, turned on, in reception, turned on, turned off, removed. During each phase, the blood flow was measured both with the subject silent and speaking.

Main outcome of study (acc. to author)

The electromagnetic non-ionizing radiation (EMR) emitted by cellular phones induce transient but significant modification of cutaneous blood flow in ear skin. But the effects on the health of human beings are still not determinate and evident because we have no element to affirm that they are harmful.
