“…Comparing the values of 222 Rn levels in West Java to 222 Rn activity concentrations elsewhere reveal that Indonesian levels are rather low. Studies in Slovenia [24], the U.S. [25], Spain [26], Taiwan [27], Hungary [28], Poland [29], Venezuela [30], Germany [31], Croatia [32], Iran [33], and Thailand [6] report 222 Rn activity concentrations in hot spring water ranging from 0.2 to 600 Bq L −1 . The radon concentration in an area is closely related to geological rock types, which in West Java have andesitic rock types that contain low uranium and radium content [34][35][36].…”

“…Radon dissolves in water that passes through soil and rock containing the natural radioactive substance [5,6]. As a result, water moving deeper through the earth's crust gathers increasing concentrations of radon and other natural radioactive materials.…”

“…Hot spring water produced under these circumstances usually contains high concentrations of 222 Rn. This is due to at least one of two natural processes: 226 Ra dissolving in the water after interacting with rock and soil in the earth or 222 Rn entering the water from rocks containing 226 Ra [6][7][8].…”

The world community has long used natural hot springs for tourist and medicinal purposes. In Indonesia, the province of West Java, which is naturally surrounded by volcanoes, is the main destination for hot spring tourism. This paper is the first report on radon measurements in tourism natural hot spring water in Indonesia as part of radiation protection for public health. The purpose of this paper is to study the contribution of radon doses from natural hot spring water and thereby facilitate radiation protection for public health. A total of 18 water samples were measured with an electrostatic collection type radon monitor (RAD7, Durridge Co., USA). The concentration of radon in natural hot spring water samples in the West Java region, Indonesia ranges from 0.26 to 31 Bq L−1. An estimate of the annual effective dose in the natural hot spring water area ranges from 0.51 to 0.71 mSv with a mean of 0.60 mSv for workers. Meanwhile, the annual effective dose for the public ranges from 0.10 to 0.14 mSv with an average of 0.12 mSv. This value is within the range of the average committed effective dose from inhalation and terrestrial radiation for the general public, 1.7 mSv annually.

“…The need to carry out the research in this area in Poland was motivated by our previous analysis of reports on similar measurements all around the world [3]. In this study radon concentrations were analyzed in the air of 17 geothermal centers: in Greece (3 centers), Iran (5), China (4) and India (5). We have found that radon levels in spas are from a few to several times higher than those in confined spaces where geothermal waters are not used (e.g., residential buildings).…”

“…Doses received by spa visitors are much lower because the time of their exposure to radon released from geothermal water is rather short. Another analysis of radon concentration in spa facilities in the world shows that the radiological protection of people working with geothermal waters plays an important role [4,5]. It seems reasonable to include spa workers staying close to geothermal waters into a dosimetric monitoring programme.…”
