Mobile Phones{{/B}}
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'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.{{U}} (46) {{/U}}
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.{{U}} (47) {{/U}}
As well, there are 2,000 transmitter towers around Australia, many in high
density residential areas.{{U}} (48) {{/U}}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 care centers,
hospitals, sports playing fields and residential areas with a high percentage of
children.{{U}} (49) {{/U}}He adds that there is also evidence that if
cancer sufferers are subjected to electromagnetic waves the growth rate of the
disease accelerates.
{{U}} (50) {{/U}}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.
A.He says there is emerging evidence
that children absorb low-level radiation at rate more than three times that of
adults.
B.By the year 2004 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.
