Chromatid damage in human lymphocytes is not affected by 50 Hz electromagnetic fields.
Cultured human blood lymphocytes were exposed during the S/G(2) phases of the cell cycle to continuous extremely low frequency (50 Hz) electromagnetic fields of 0.23, 0.47 or 0.7 mT either alone or immediately after an acute exposure to 1.0 Gy of gamma rays. The ionising radiation, as expected, induced chromosomal aberrations of the chromatid-type observed at the next metaphase. The field applied alone did not induce chromosomal damage nor did it modify the frequency of aberrations caused by the gamma rays.
