【简答题】
Mobile Phones Mobile 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&39;s 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 axe 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. Robert Bell suggests that until more research is completed the Government should ban construction of phone towers from within a 500 metre radius of school grounds, child cam centres, 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 ale 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. (46) 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 brings more harm than benefit.
