Medical/biological Study (experimental study)

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

PubMed Entry

Journal web site

Aim of study (according 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.

Endpoint

• genotoxicity/mutation: chromatid aberration

Exposure
General category: magnetic field, 50/60 Hz (AC)

Field characteristics	Parameters
50 Hz exposure duration: continuous during S phase and G2 phase	magnetic flux density: 0.23 mT magnetic flux density: 0.47 mT magnetic flux density: 0.7 mT

Exposed system:
intact cell/cell culture (in vitro)

Methods
Endpoint/Measurement parameters/Methodology

• genotoxicity/mutation: chromatid aberration (chromatid gaps, breaks, exchanges; Giemsa stain, light microscopy)

Main outcome of study (according 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.

(Study character: medical/biological study, experimental study, blind study, follow-up study)
