DNA strand breaks increased with exposure time, being largest at 15-19 hours. The DNA strand break levels declined thereafter, but did not return to basal levels.
Cell strains of different donors exhibited different basal levels, maxima and end levels of DNA strand breaks.
The fibroblasts from older individuals exhibited higher DNA strand break levels and they started to decline later than those from younger donors.
These findings suggest an age-related slow down of DNA repair efficiency of extremely low frequency electromagnetic field induced DNA strand breaks.
