A planning application to build a 50ft (15.24m) mobile phone mast in Guernsey's St Martins area has met with an angry reaction from residents.
The mobile phone mast would be erected in St Martins
Wave Telecom wants to erect a pole at Les Hubit Farm.
But people living nearby are worried about possible health risks, although there is no conclusive scientific evidence to support their claims.
They also fear the mast will have an adverse effect on property values in the area.
Joan Roget, whose home overlooks the proposed site, said: "There has been a lot of evidence collated on the mainland to suggest they could cause cancer or leukaemia.
"It's not 100% but there is enough evidence to cause concern.
"I am also worried it may well effect the animals. The milking parlour is nearby and the nursery field for calves.
"If radiation gets into their system then there are wider implications because the milk is sold far and wide."
Wave Telecom managing director Tim Ringsdore said the company took the concerns very seriously, but he tried to allay the fears of residents.
"I am confident our masts are well within the guidelines set out within the telecommunications industry," he said.
"I am confident the reports the regulator (Guernsey Office of Utility Regulation) has just undertaken over the last few months to investigate local sites to check for their safety will come out in our favour and will show we are thousands of times within the recommended guidelines."
