This Public Health England map above highlights the areas of the country where it has been predicted that high radon levels are most likely to be found. The darker areas are the more radon saturated areas.

Radon Protection (New Homes)
Protecting New Buildings from Radon:
- Basic Radon Protection: - protection is provided by a damp proof membrane modified and extended to form a radon-proof barrier across the ground floor of the building.
- Full Radon Protection:- comprises of a radon-proof barrier across the ground floor and provision for subfloor depressurization (a radon sump) or ventilation (a ventilated subfloor void). It is important to realise with full radon protection that the sump is not activated when the house is built. It is capped and available for use as a secondary measure in case the radon-proof barrier is insufficient for reducing radon levels below the Action Level 200 Bq m-3.

- Activate: - a fan can be added to the sump pipe OR
- Passive: - the cap can be removed and a pipe added to above the eaves of the roof.
- Add a fan to increase ventilation to the under-floor void. If only basic protection is fitted, a radon sump of underfloor ventilation can be fitted - see our guidance on how to reduce radon levels in existing properties. Once these changes have been made- test again to ensure that the radon levels are reduced sufficiently.
