Assessment of the indoor gamma dose rates in 15 Portuguese thermal spas(Book Chapter)

Studies in Systems, Decision and Control


In Portugal, most of the average annual dose to which the population is exposed by natural sources is from radon (57%) and terrestrial gamma radiation (18%). In this study, the indoor gamma radiation dose rates were evaluated in 15 Portuguese thermal spas between 2011 and 2015. Gamma radiation dose rates were measured with a Geiger counter type GAMMA SCOUT ® (GS3). The readings of the dose rate were hourly collected during a period of time ranging between 25 and 45 days, in different treatment rooms within each one the selected facilities: inhalation treatment rooms, thermal pools and vapors areas. All registered values for the gamma dose rates were lower than 1 mSv/year, and therefore the contribution of the external dose to the calculation of the annual effective dose is negligible. © Springer Nature Switzerland AG 2019.
