Radon exposure in Slovenian spas

Area of Science:

• Environmental Health
• Radiological Protection
• Occupational Health

Background:

• Spas utilize natural resources, which can include elevated levels of radon and gamma radiation.
• Monitoring indoor radiation levels is crucial for ensuring the safety of staff and visitors.
• Slovenian spas are popular destinations, necessitating an assessment of their radiological environment.

Purpose of the Study:

• To measure radon and gamma dose rates in five Slovenian spa locations.
• To assess the potential exposure risks for personnel working in these spas.
• To determine if current operational conditions mitigate radiation exposure.

Main Methods:

• Field surveys were conducted to measure radon concentrations (Bq x m(-3)) and gamma dose rates.
• Measurements were taken under normal operational conditions in the spas.
• Data were analyzed to compare against established safety guidelines.

Main Results:

• Indoor radon concentrations in the surveyed spas rarely exceeded 200 Bq x m(-3) and were generally lower.
• Effective ventilation systems were identified as a key factor in maintaining low indoor radon levels.
• Gamma dose rates were within acceptable limits for the surveyed locations.

Conclusions:

• The current operational conditions and ventilation systems in the surveyed Slovenian spas effectively control indoor radon concentrations.
• There is no evidence of elevated radiation exposure risk to personnel under present working conditions.
• The findings support the continued safe operation of these facilities regarding radon and gamma exposure.
