Police say they know of no health problems with the Tetra system

Campaigners opposed to the Airwave system on health grounds mounted a protest outside the meeting of Kerrier District Council.

Sites had been earmarked for the police Tetra system in Maenporth, St Keverne and Porthleven.

Council officers had recommended approval and an appeal is expected to be lodged against the decision.

The Airwave system has been commissioned by the Home Office for all police forces in the country.

It is a digital replacement of the current radio system used by officers.

But it is already behind schedule because of planning delays and is now due to become operational next year.

Residents living near the proposed sites said they were concerned about any potential health risks from the equipment.

Between the three sites, more than 177 people raised objections, and more than 460 signatures were collected on two petitions.

But Devon and Cornwall Police said they knew of no health problems with the system, which is used by other forces, and that it was vital it was installed.

The police had previously warned that cover in some rural areas could be affected if the new radio system was not installed.
