“…Radon is a radioactive gas from rocks and soils that tends to accumulate in the air of underground cavities and, in certain quantities, is very dangerous to human health (Robertson et al., 2013 ). It should therefore be considered as one of the main occupational health problems in volcanic tourist caves (Torres‐González et al., 2019 ).…”

Tourist volcanic caves are in high demand for ecotourism and geotourism lovers, as well as by sun and beach tourists as a complementary activity during their holidays. There are six tourist volcanic caves in the Canary Islands, all of them managed by the local administration of the island. The managers of these caves must ensure the safety of visitors and workers, who are exposed to natural hazards, such as radon, inherent to the environment in which the activity takes place. The methodology for analyzing natural radon radiation is based on the latest studies published by experts in this field and on previous experiences in tourist caves. This article proposes a protocol for the correct management of radon in tourist caves in the Canary Islands, adapted to current regulations, to mitigate effects on the health of visitors and workers.

The Sierra de Lújar, located in the south of Granada (Spain), hosts one of the few currently active underground fluorite mines in Spain. Considering that high concentrations of radon gas, which is the second leading cause of lung cancer after tobacco, can occur in underground workplaces, the concentration of radon gas inside a fluorite underground mine has been measured, in order to prevent health risks to workers. QueryAlthough no significant concentration of radioactive elements has been detected in the geochemical analysis, the radon gas concentration values measured ranged between 28 and 1211 Bq m−3, and there were important variations, depending on the area of the mine. Some values exceed the limits established by European regulations. Despite these high values, the annual effective dose (E) ranges between 0.13 and 5.71 mSv, in most cases being below 3 mSv, which is the recommended value in underground mines. Improvement in the ventilation of main galleries, especially in the benefit plan area (level 423), the isolation of mined-out areas using bulkhead, continuous monitoring of radon concentration, and periodic health controls to workers are estimated as the main mitigation measures to take into consideration. The findings from this research suggest that workers in this underground fluorite mine may face substantial risk of receiving radon doses that could meet or surpass the recommended thresholds established by European regulations. This underscores the imperative for additional investigations into radon levels within underground operations in Spain.

Water galleries are mines that seek to supply drinkable and irrigation water from the aquifer, in order to meet the demand for water in the Canary Islands. This sort of work entails a series of health risks in the form of gases. This document compiles three different studies on the gases that can be found in water galleries in the Canary Islands, having divided the document as follows: 1) the presence of carbon dioxide in 13 galleries in operation on the island of Tenerife; 2) the presence of radon gas in galleries on the islands of Tenerife, El Hierro and La Palma; and 3) the incidence of gases that are harmful to health in a thermal water gallery on La Palma. The results have shown that, in general, the water galleries contain concentrations of gases which are toxic to human health, such as radon, where average radon values measured with both passive detectors are from less than 800 Bq/m 3 to around 10,200 Bq/m 3 . Therefore, it is important to protect the health of the workers who undertake the maintenance of these installations.
