A New Methodology for Defining Radon Priority Areas in Spain.

Area of Science:

• Environmental Science
• Radiation Protection
• Public Health

Background:

• European Basic Safety Standards mandate National Radon Action Plans to identify radon risk areas.
• The Spanish Nuclear Safety Council (CSN) uses radon potential to define priority areas.
• Accurate radon risk mapping is crucial for protecting public health in homes and workplaces.

Purpose of the Study:

• To develop an improved methodology for creating a radon potential map in Spain.
• To enhance the definition and delimitation of areas potentially exposed to radon gas.
• To offer a more precise tool for national radon action plans.

Main Methods:

• Utilized indoor radon measurements, gamma radiation exposure data, and geological information.
• Developed a novel data processing approach for radon potential mapping.
• Compared the new methodology against the existing CSN approach.

Main Results:

• The proposed methodology provides an improved definition of radon-exposed areas in Spain.
• Simple data processing significantly enhances the accuracy of radon potential mapping.
• The new map offers better delimitation of radon priority areas.

Conclusions:

• The developed methodology offers a more effective way to identify radon-exposed areas compared to current methods.
• This approach supports the accurate implementation of National Radon Action Plans.
• The methodology is compatible with the European Commission-Joint Research Center's mapping systems.
