NEW, EFFICIENT AND GENERALLY APPLICABLE DESIGN OF RADON-PROOF INSULATIONS-A PROPOSAL FOR A UNIFORM APPROACH

Area of Science:

• Building science
• Environmental health engineering
• Material science

Background:

• Current methods for dimensioning radon-proof insulation yield inconsistent results.
• This inconsistency hinders the accurate assessment of waterproofing material suitability.
• Lack of standardized methods complicates effective radon mitigation strategies.

Purpose of the Study:

• To introduce a new, universally applicable, and straightforward method for dimensioning radon-proof insulation.
• To address the shortcomings of existing, disparate dimensioning techniques.
• To enable reliable and optimized design of radon barriers.

Main Methods:

• The proposed method involves comparing two key values: the radon resistance of the insulation material and the minimum required radon resistance.
• Radon resistance is determined by insulation thickness and its radon diffusion coefficient, typically available from manufacturers.
• Minimum radon resistance is determined based on site-specific radon risk and building parameters.

Main Results:

• The new method provides a unified approach, overcoming the discrepancies found in existing techniques.
• It allows for accurate determination of required insulation thickness for effective radon proofing.
• The method facilitates a fast, reliable, and optimized design process for radon-proof insulations.

Conclusions:

• The developed method offers a significant improvement over existing approaches for dimensioning radon-proof insulation.
• It ensures a more accurate and consistent approach to radon mitigation in buildings.
• This facilitates better material selection and optimized design for radon barriers, enhancing building safety.
