A GIS-derived dataset estimating the potential for radon gas in indoor air across Nova Scotia. The model integrates bedrock geology, surficial geology, and airborne gamma-ray spectrometry layers to produce a cumulative radon score ranging from 25 to 275. It was created by the Government of Nova Scotia using a methodology detailed in O'Reilly et al. (2010).
Use Cases
- Identify high-risk areas for radon exposure based on the integrated geology and uranium concentration layers.
- Support public health recommendations for radon testing by mapping potential scores across the province.
- Validate GIS-based environmental hazard models using the described methodology of weighting and scoring data layers.
Strengths
- Model is based on three comprehensive digital data layers covering the entire province.
- Radon scores are derived from a specific methodology with a defined scoring range of 25 to 275.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The model's subjective scoring from 1 to 100 within each layer may introduce bias.
