An international expert on mobile phones has suggested that Jersey should use fibre optic cables rather than masts to transmit signals.
Health fears have been raised by islanders at public meetings
Dr George Carlo said there is too much background radiation already in the island to make the further use of phone masts safe.
A States scrutiny panel is reviewing mobile phone masts and has been taking advice from scientific experts.
The panel will make its findings public in the spring.
Some of the expert evidence has been conflicting.
A World Health Organisation (WHO) scientist claimed symptoms associated with mast radiation were often psychological.
But another scientist, who has advised government agencies on radio and microwave issues, claimed living within 500yds (457m) of a mast was a health risk.
People living in Jersey have attended a series of public meetings to air their views and health concerns.
