6.1 The RADON POTENTIAL DATASET has been developed at 1:50 000 scale and must not be used at larger scales.
6.2 A 75-m buffer has been applied to the 1: 50 000 scale base radon potential data. All spatial searches of the RADON POTENTIAL DATASET should be done without applying any additional buffer.
6.3 The RADON POTENTIAL DATASET consists of vector polygons and is available in a range of GIS formats, including ArcGIS (.shp), ArcInfo Coverages and MapInfo (.tab). More specialised formats may be available but may incur additional processing costs.
6.4 The RADON POTENTIAL DATASET is concerned with radon potential related to NATURAL geological sources only. The data do NOT cover the impacts of man-made features, apart from the impact of ironstone mining over the Northampton Sand Formation.
6.5 The RADON POTENTIAL DATASET is based on, and limited to, an interpretation of the records in the possession of The British Geological Survey and The Health Protection Agency at the time the base radon potential data set was created (2006).
6.6 An indication of high radon potential does not necessarily mean that an individual property will have a high radon concentration. The only way to find out whether a property is in fact above, at or below the Action Level is to carry out a radon measurement. Guidance on measuring radon can be obtained from the HPA (www.hpa.org.uk/radiation/radon).
6.7 All address searches against the data should be made using Ordnance Survey ADDRESS-POINT® coordinates rounded to 1 metre as described in Section 4.8.
6.8 Address searches against the data should take into account the positional accuracy flags within the ADDRESS-POINT® database, and users recommended to seek alternative location methods for inaccurately located addresses (see note above).
