Introduction to radon protection provisions

The guidance in Section 3 is to ensure that where a dwelling is located in the radon risk category of 1-3% or any category above this risk on the radon map in 'Radon in Dwellings in Northern Ireland: 2009 Review and Atlas' then radon protection will be required. Where man-made contaminants have not been identified in the normal way at planning stage, but are discovered during the building process, then in this exceptional circumstance the district council will require the site to be remediated.
