Summary: In this study, we investigated the dynamics of radon concentration in the touristic section of La Cueva del Viento volcano lava tube. The results showed that seasonal and daily variations of indoor radon concentrations were influenced by pluviometry and external air temperature. A suitable model for short-term forecasting was developed using time series and frequency analysis methods. The annual effective doses received by touristic guides and visitors were found to be approximately 2 mSv/yr and 4 μSv/hr, respectively. Based on the results, it was concluded that La Cueva del Viento is safe for tourists and guides, but a regular monitoring program should be implemented.
