Radon Potential Indicative Atlas For Northern Ireland Grid

A 1-km grid map classifies Northern Ireland by the highest radon potential found within each square. The dataset provides a simplified, indicative overview of areas where homes have an estimated 1% or greater chance of exceeding the radon Action Level of 200 Bq m⁻³. It is derived from the definitive Radon Potential Dataset and published in a 2015 report by PHE, GSNI, and BGS.

Use Cases

• Identify 1-km grid squares with the highest radon potential class to prioritize public health interventions.
• Cross-reference radon Affected Areas, defined as having ≥1% chance of exceeding the Action Level, with population density data for risk assessment.
• Analyze spatial patterns of radon potential to inform geological surveys and building regulations in Northern Ireland.

Strengths

• Provides a spatially explicit overview with data aggregated to a standardized 1-km grid resolution.
• Based on the definitive Radon Potential Dataset for Northern Ireland, authored by authoritative bodies (PHE, GSNI, BGS).
• Clearly defines the radon Action Level (200 Bq m⁻³) and the threshold for Affected Areas (≥1% chance of exceedance).

Limitations

• Data is indicative and simplified, classifying each grid square by its highest potential rather than providing granular measurements.
• The underlying definitive dataset and methodology are from a 2015 publication, which may not reflect very recent changes or measurements.
