This study evaluated radon measurement protocols in a Hungarian Turkish bath, finding personal radon meters most accurate for dose estimation. Annual effective doses from radon were 0.83 mSv (old) and 0.17 mSv (new) buildings.
Area of Science:
- Environmental Health
- Radiological Protection
- Building Physics
Background:
- Radon exposure in buildings is a significant public health concern.
- Turkish baths, with their unique environmental conditions, require specific radon assessment protocols.
- Understanding radon and thoron decay product contributions is crucial for accurate dose estimation.
Purpose of the Study:
- To establish an effective radon measurement protocol for historical and modern structures.
- To quantify radon and thoron exposure in the old and new sections of the Eger Turkish bath.
- To compare different radon measurement techniques for dose assessment accuracy.
Main Methods:
- Application of various radon measurement methods, including personal radon meters.
- Measurement of radon and thoron short-lived decay products.
- Assessment of external gamma dose and waterborne radon concentrations.
Main Results:
- Personal radon meters yielded the most accurate dose estimations.
- Estimated annual effective doses from radon were 0.83 mSv (old building) and 0.17 mSv (new building).
- Thoron decay products contributed approximately 5% to the total dose; waterborne radon doses varied (0.05-0.14 mSv/y).
Conclusions:
- Personal radon dosimetry is recommended for precise radon exposure assessment in similar environments.
- Radon levels in the old building were significantly higher than in the new building.
- A comprehensive measurement strategy is essential for evaluating radiological risks in unique building structures.
