which accept visitor almost throughout year, and significant seasonal variations were observed. …

… If a show cave has a radon concentration close to the limit established by the local regulation,
optional activities, like underground lunchrooms, should be avoided. In principle, also …

… Based on the above variables, we measured radon concentration in two show caves:
Coves de Campanet (hereafter Campanet) and Coves d'Artà (Artà) and in three non-touristic …
