To examine the mutagenic and co-mutagenic effects of an electromagnetic field at 835 MHz (the most widely used communication frequency band in Korean CDMA mobile phone networks) on bacteria.
To determine bacterial mutagenicity, histidine auxotrophic strains of Salmonella typhimurium and a tryptophan auxotrophic strain of Escherichia coli were used. To study co-mutagenicity exposure was conducted with the mutagens 4-nitroquinoline-1-oxide, sodium azide and cumene hydroxide.

| Setup | Cultivated cells on three Petri dishes (10 cm in diameter and 2 cm high) stacked in a jig fixture were exposed to uniform TEM-mode EMF in the TEM cell under controlled conditions (5% CO2 and 95% air and a temperature of 37°C). |
| Additional info | Control agar plates were incubated without EMF in a standard bacterial incubator. |

The results showed that an 835-MHz electromagnetic field was neither mutagenic nor co-mutagenic in the tested bacteria. In addition, the exposure to 835-MHz did not change DNA degradation in vitro.
