This study was focused on the risk assessment of whether radiofrequency
electromagnetic fields generated by mobile phone is cytogenetically toxic or not. We
conducted the effects of 835-MHz electromagnetic field (EMF) on DNA strand breaks in
mouse thymic lymphoma L5178Y Tk±/- cells using alkaline comet assay. EMF frequency
835-MHz we chosen is one of the most popular communication frequency bands in
Korean code-division multiple-access (CDMA) mobile phone system. The cells were
exposed to 835-MHz EMF alone or 835-MHz EMF combined with cyclophosamide (CPA)
or 4-nitroquinoline-1-oxide (4NQO) at specific absorption rate (SAR) of 4.0W kg-1 for
24 and 48 hrs. DNA damage expressed as tail moment was increased more than two-fold
after exposure to 835-MHz EMF for 24 and 48 hr. In particular, CPA for 48 hr and 4NQO
for 24 hr enhanced notably the tail moment to 9-fold and 16-fold in the presence of
835-MHz EMF, respectively, compared to each single treatment. From these results, it
appears that exposure to CDMA-mobile phone radiation at 835-MHz frequency may
potentiate DNA strand breaks of mouse thymic lymphoma L5178Y Tk±/- cells under the
defined conditions of this study.
