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.

共用题干Mobile PhonesMobile phones should carry a label if they proved to be a dangerous source of radiation,according to Robert Bell,a scientist.And no more mobile phone transmitter towers should be built until the long-term health effects of the electromagnetic radiation they emit are scientifically evaluated,he said."Nobody is going to drop dead overnight but we should be asking for more scientific information,"Robert Bell said at a conference on the health effects of low-level radiation.______(46) A report widely circulated among the public says that up to now scientists do not really know enough to guarantee there are no ill-effects on humans from electromagnetic radiation.According to Robert Bell,there are 3.3 million mobile phones in Australia alone and they are increasing by 2,000 a day.______(47)As well,there are 2,000 transmitter towers around Australia,many in high density residential areas.______(48)The electromagnetic radiation emitted from these towers may have already produced some harmful effects on the health of the residents nearby.Robber Bell suggests that until more research is completed the government should ban construction of phone towers from within a 500 meter radius of school grounds,child care centers,hospitals, sports playing fields and residential areas with a high percentage of children.______(49)He adds that there is also evidence that if cancer sufferers are subjected to electromagnetic waves the growth rate of the disease accelerates.______(50)According to Robert Bell,it is reasonable for the major telephone companies to fund it. Besides,he also urges the government to set up a wide-ranging inquiry into possible health effects.________（49）A:He says there is emerging evidence that children absorb low-level radiation at a rate more than three times that of adults.B:By the year 2000 it is estimated that Australia will have 8 million mobile phones;nearly one for every two people.C:"If mobile phones are found to be dangerous,they should carry a warning label until proper shields can be devised,"he said.D:Then who finances the research?E:For example,Telstra,Optus and Vodaphone build their towers where it is geographically suitable to them and disregard the need of the community.F: The conclusion is that mobile phones bring more harm than benefit.
