RF-Induced DNA Breaks Reported in China

Research scientists in China have found that relatively low-level RF
radiation can lead to DNA breaks, according to a briefing paper prepared for
the cell phone industry obtained by Microwave News.

At the 4th International Seminar on EMFs and Biological Effects, held in
Kunming China, September 12-16, Zhengping Xu of the Zhejiang University
School of Medicine reported that cells exposed to a pulsed 1800 MHz RF
radiation at an SAR of 3 W/Kg for 24 hours showed a statistically
significant increase in DNA damage. The Mobile Manufacturers Forum (MMF), an
industry lobbying group based in Brussels, circulated the news in a
September 22 Research Briefing.

Xu’s Bioelectromagnetics Laboratory now joins a growing number of other labs
that have found RF-induced DNA breaks. The effect was first reported more
than a decade ago by Henry Lai and N.P. Singh of the University of
Washington, Seattle (see MWN, N/D94). From the outset, Lai and Singh’s work
has been repeatedly assailed by the cell phone industry and their
consultants —most recently by Sheila Johnston and Vijayalaxmi, two members
of the board of directors of the Bioelectromagnetics Society (see March 29
entry below. They ciaimed to have refuted the Lai-Singh findings.

Last year, the European Union-sponsored REFLEX Project announced that 1800
MHz radiation could lead to DNA breaks. Those results were published this
summer in Mutation Research.

The MMF also noted that C.K. Chou of Motorola (a member of the MMF)
complained at the meeting that it is difficult to publish “negative” results
in China. (WHO ’s Mike Repacholi made a similar charge at the last Chinese
EMF seminar held in Guilin in 2003, according to the MMF.) Xu disputed this,
the MMF added.
