Study type: Medical/biological study (experimental study)

Absence of genotoxicity in human blood cells exposed to 50 Hz magnetic fields as assessed by comet assay, chromosome aberration, micronucleus, and sister chromatid exchange analyses med./bio.

Published in: Bioelectromagnetics 2004; 25 (1): 41-48

Aim of study (acc. to author)

To evaluate the effects of 50 Hz magnetic fields in human blood cells exposed in vitro. The effects of a combined exposure with X-rays were also investigated.



Exposure Parameters
Exposure 1: 50 Hz
Exposure duration: continuous for 2 h

General information

The following exposure condition were performed: sham control, positive control (1 Gy), ELF exposed and ELF exposed followed by 1 Gy exposure.

Main outcome of study (acc. to author)

Data obtained do not show any significant difference between extremely low frequency magnetic fields exposed and unexposed samples. Moreover, no synergistic effect with ionizing radiation has been revealed. A slight but significant decrease of cell proliferation was evident in extremely low frequency magnetic fields treated cell samples and cell samples subjected to the combined exposure.
