​This report provides the results of the radon survey undertaken in 2012 and includes a discussion of the impact of radon on human health.

Over the last few years, concern has been raised by Members of the States and several members of the public about radon risks.

This work has been done in partnership with the UK Health Protection Agency (HPA). The contribution of the Radiation Protection Division of the HPA is acknowledged, with particular thanks to Jane Bradley, who has supported several of the recent surveys in Jersey.

The 2012 survey was carried out across the Channel Islands as a joint initiative.

Historically there were radon surveys in Jersey in 1987, 1992 and 1997, and in Guernsey there was a survey in 1985. In 2012 tests were also carried out in Herm, Alderney and Sark.
