听力原文:Italian scientists have raised new health concerns about the safety of using mobile phones, with research showing radio waves from the handsets makes cancerous cells grow more aggressively. When Fiorenzo Marinelli and his colleagues at the National Research Council in Bologna exposed leukemia cells in the laboratory to 48 hours of continuous radio waves they initially killed the cancer cells but then made the surviving tumor cells replicate more rapidly.
We don't know what the effects would be on healthy human cells, Marinelli told New Scientist magazine. In the Italian study, after 24 hours 20 percent more leukemia cells died than healthy cells but longer exposure to the radio waves triggered genes in the surviving cancer cells to divide aggressively.
The results of the study do not show any direct threat to human health but they support the belief of some scientists who say radiation can damage DNA and destroy the cell repair system, thus making tumors more deadly. But animal studies, including recent research by Australian scientists at the Institute of Medical and Veterinary Science in Adelaide, have shown that radiation from mobile phones does not trigger the growth of tumors.
The WHO (i.e., The World Health Organization) has called for more research into the potential health hazards of mobile phones and has urged people to limit their use of them. A British government inquiry, which concluded that there was no evidence that mobile phones are a danger to health, has advised parents to discourage their children, whose brains are still developing, from using them excessively.
What is the speaker's main topic?
A.Effects of using mobile phones on healthy human cells.
B.Risks of developing cancer involved in the use of mobile phones.
C.Damage to healthy cells caused by the use of mobile phones.
D.The potential health hazards of mobile phones on humans.
