Resumen
Vapor Cave shows a high radon air concentration related to the Alhama de Murcia Fault (Pérez-López et al., 2016). A time series (2017 – 2019) of radon emission was obtained by monitoring with handled alpha-counter loggers (SARAD-home) and by using high-resolution devices RAD7 and ALPHAGUARD. Averaged concentration of 222Rn was 52.9 +/- 6.1 kBq/m3, osci- llating between 35.6 and 67.8 kBq/m3. This value implies that Vapor Cave is the Spanish cave with the highest natural radon dose, higher than Castañar de Ibor (average concentration of 34.6+/- 5.6 kBq/m3, Álvarez-Gallego et al., 2015). Also, we have compared time series of 222Rn with earthquakes recorded in near-field (10 km diameter) and far field (50 km diameter). The maximum recorded earthquakes during this period were M 3.5 in far-field and M2.4 in near-field.
