Radon mitigation in the workplace in Spain: a cross-sectional interview-based study.

Area of Science:

• Occupational Health
• Environmental Health
• Public Health

Background:

• Radon is a radioactive gas posing health risks in workplaces.
• Understanding employer mitigation practices is crucial for public health.
• Pre-regulation data on radon mitigation in Spain is limited.

Purpose of the Study:

• Evaluate radon mitigation frequency among Spanish employers.
• Identify determinants influencing mitigation decisions.
• Determine reasons for the lack of radon mitigation.

Main Methods:

• Cross-sectional study of 32 employers in Spain (2015-2022).
• Systematic identification of employers who measured occupational radon.
• Phone interviews using an ad hoc questionnaire.

Main Results:

• Overall radon mitigation frequency was 53%.
• Mitigation increased with company size and higher radon levels (67% for ≥1000 Bq/m³).
• Primary reason for non-mitigation: low perception of radon as a health risk.

Conclusions:

• Workplace radon mitigation requires significant improvement in Spain.
• Employers need enhanced guidance and accessible mitigation services.
• Proactive measures are essential for regulatory compliance and worker safety.
