“…The considerable variability of the radon concentration observed in each thermal establishment is influenced by many factors, namely: rock type, double glazing, window opening habits, building materials used in the walls, type of flooring and draught proofing, the tightness of the building barriers with the soil and, ultimately, on the ventilation level, natural or mechanical (Faísca et al, 1992;Gunby et al, 1993).…”

In this study, an assessment of indoor radon concentration and gamma dose rates were carried out in 16 Portuguese thermal spas. Indoor gamma dose rates measurements were made using a Geiger counter (Gamma Scout -GS3) and radon concentration measurements were carried out using CR-39 detectors. The detectors were exposed for an extended period of time (in average 42 days). The results showed that gamma doses rates are generally low but, in several cases, radon concentration exceeded national as well as international standards, namely the reference level recommended by the Directive 2013/59/EURATOM (300 Bq/m3) and the threshold for protection (400 Bq/m3) from the Portuguese legislation. The annual effective doses deriving from external radiation (gamma dose rates) and indoor radon concentration showed the need to implement measures to optimize the radiation protection of the workers against ionizing radiation.

“…In the framework of that study, indoor radon measurements were first carried out in dwellings located in technologically enhanced naturally radioactive zones and it was later enlarged to the entire country (Faísca et al, 1992). Radon is a radioactive gas that occurs in rocks, soils, air and water in variable concentrations and is considered an environmental health hazard.…”

The book series is dedicated to the United Nations International Year of Planet Earth. The aim of the Year is to raise worldwide public and political awareness of the vast (but often under-used) potential of Earth sciences for improving the quality of life and safeguarding the planet. Geoscientific knowledge can save lives and protect property if threatened by natural disasters. Such knowledge is also needed to sustainably satisfy the growing need for Earth's resources by more people. Earths scientists are ready to contribute to a safer, healthier and more prosperous society. IYPE aims to develop a new generation of such experts to find new resources and to develop land more sustainably.
