Mobile phone masts in Guernsey have been given the all-clear by the regulator, despite public safety fears.
Random checks will carried out on masts later this year
Forty-eight radio antennae were tested and the emissions were found to be well within international guidelines.
The survey, commissioned by the Office of Utility Regulation (OUR), is the first review of all of Guernsey, Alderney and Sark's radio masts.
Telecoms operators have been commended for the high degree of compliance with international standards.
The standards are set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).
But auditors CDS have recommended some changes, mainly involving ensuring that access to the masts is suitably restricted.
They have also suggested that airport antennas are reduced in power.
John Curran, the director general of OUR, has welcomed the findings.
He said: "This is the first audit of emissions from the Bailiwick's radio masts, and it's reassuring that all sites comply with the most stringent international standards.
"The high degree to which they have all complied is also very important and the operators have demonstrated they have in place processes and procedures that ensure their networks are operated in a professional manner."
OUR has also announced it will be working with UK regulator Ofcom to carry out random site checks later this year to ensure new masts comply with safety standards.
