The dataset classifies municipalities in the French department of Nièvre (58) based on their potential for radon gas risk. It was produced by the Bureau de Recherches Géologiques et Minières (BRGM) for the Nuclear Safety Authority, with work led by the IRSN. The classification, last updated in July 2021, maps radon potential across metropolitan France, categorizing municipalities into three risk levels based on geological uranium content and transport factors.
Use Cases
- Prioritizing public health screening campaigns based on municipality radon risk category.
- Informing building regulations and construction standards based on geological radon potential.
- Cross-referencing radon risk with local health statistics based on the described risk categories.
- Identifying areas for targeted radon measurement studies based on the described geological formations.
Strengths
- Provides a clear, three-tier classification system (Category 1, 2, 3) for radon risk.
- Based on a national mapping effort by the IRSN covering the entire metropolitan French territory.
- Description includes specific performance metrics for each category, such as 'more than 40% of buildings exceed 100 Bq.m-3' in Category 3 areas.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
