Four passive sampling elements (quatrefoil)--I. Monitoring radon and its progeny by surface-contamination monitors

Area of Science:

• Environmental Science
• Nuclear Physics
• Radiation Detection

Background:

• Radon and its decay products are significant indoor and environmental airborne radionuclides.
• Traditional methods for measuring radon and its decay products can be complex and limited in application.
• Passive sampling elements offer a potential alternative for radionuclide detection.

Purpose of the Study:

• To introduce and evaluate novel passive sampling elements (quatrefoil) for radionuclide detection.
• To demonstrate the feasibility of using these samplers with a Pancake Geiger-Muller counter for radon and decay product measurements.
• To highlight the advantages of this method for challenging measurement scenarios.

Main Methods:

• Development of four passive sampling elements designed to capture airborne radionuclides.
• Utilizing a large collecting-area sampler with low surface density for enhanced detection.
• Employing a Pancake Geiger-Muller counter for real-time or passive detection of surface-bound radionuclides.

Main Results:

• The developed passive samplers successfully transform airborne radionuclides into detectable surface-bound sources.
• Measurements of radon and its decay products were achieved using a Pancake Geiger-Muller counter.
• Effective measurements were demonstrated in indoor environments, soil, and water samples.

Conclusions:

• The novel passive sampling elements, coupled with a Pancake Geiger-Muller counter, provide a viable and simplified method for measuring radon and its decay products.
• This technique overcomes limitations of existing technologies, enabling measurements in previously difficult or impossible settings.
• The approach offers a promising tool for environmental monitoring and radiation safety.
