Chromatid damage in human lymphocytes is not affected by 50 Hz electromagnetic fields. med./bio.

Published in: Radiat Prot Dosimetry 2006; 121 (3): 321-324

Aim of study (acc. to author)

This in vitro study was performed to study genotoxic effects of extremely low frequency electromagnetic field and/or gamma rays (1 Gy) in human lymphocytes during the S phase and G2 phase.

Background/further details

Lymphocytes were isolated from one blood sample of a healthy, non-smoker, 49 years old woman.

Main characteristics
Frequency 50 Hz
Type
Waveform
Exposure duration continuous during S phase and G2 phase
Exposure setup
Exposure source
Setup 2 solenoid coils, each enclosed in a µ-metal drum
Sham exposure A sham exposure was conducted.
Additional info half of the samples were exposed only to the magnetic field; the other half was exposed to the magnetic field after exposure to 1.0 Gy gamma rays; immediately the tubes went into the coils. Colcemid was added at intervals 0, 1, 2, 3 h.

Main outcome of study (acc. to author)

The exposure to extremely low frequency electromagnetic field alone did not induce chromatid damage nor did it modify the frequency of chromatid aberrations caused by the gamma rays.
