Experiences with accreditation for radon measurement laboratories

Area of Science:

• Environmental Health
• Radiation Protection
• Metrology

Background:

• Austrian national law, implementing Council Directive 2013/59/EURATOM, mandates radon monitoring in designated priority regions.
• Employers in these regions must engage authorized radon monitoring services for workplace assessments in basements and ground floors.
• This legislation presents significant challenges for businesses, authorities, and measurement service providers.

Purpose of the Study:

• To provide an overview of the experiences and challenges encountered in becoming an accredited and authorized radon monitoring body.
• To serve as a practical guideline for laboratories pursuing accreditation for radon activity concentration measurements.
• To highlight specific technical and regulatory hurdles in radon measurement and accreditation.

Main Methods:

• Utilizing both integrating and time-resolved radon measurement equipment for monitoring.
• Describing the process of achieving accreditation and authorization as a radon monitoring service.
• Identifying and detailing key challenges in measurement uncertainty determination and metrological traceability.

Main Results:

• Successful accreditation and authorization as a radon monitoring body were achieved.
• Key challenges identified include metrologically traceable calibration of track-etch detectors and ensuring information beyond ISO 11665 standards.
• The availability and participation in proficiency tests were crucial but presented difficulties.

Conclusions:

• Accreditation as a radon monitoring body requires overcoming specific metrological and logistical challenges.
• Adherence to national legislation necessitates robust measurement protocols and uncertainty evaluations.
• This experience provides valuable insights for other laboratories seeking to enter the field of radon monitoring.
