“…No published literature is available on the use of 222 Rn for determining the residence time of pipe water and for backtracking the water sources. However, a number of studies employ 222 Rn measurements in pipe networks to assess the radioactivity hazard of the water (Thabayneh, 2015;Büyükuslu et al, 2018). The current study is apparently the first in using 222 Rn to determine the water source and residence time in pipe networks.…”

This study demonstrates the use of environmental tracers (Water isotopes-δ18O–δ2H, Radon-222Rn, and Electrical Conductivity-EC) as complementary tools for backtracking the water source, estimating pipe water residence time, and monitoring the instability of the water quality. Using the capital of Ethiopia, Addis Ababa, as a case study site, we demonstrate that water isotopes (δ18O andδ2H) effectively backtrack the tap water to its source (springs, reservoirs, shallow aquifers, or deep aquifers). 222Rn is shown to be effective for discriminating groundwater-sourced pipe networks from those that are dominated by surface waters. Our reconnaissance survey reveals that 222Rn, a tracer previously not considered to determine the pipe water residence time, can be used effectively to determine pipe water residence time in groundwater-sourced pipe networks. We recommend further research to explore the capability of 222Rn as a robust indicator of the pipe water residence time in an urban piped water network. The tracers reveal that 50% of the city obtains its water from groundwater and that the groundwater-sourced areas of the city show the highest water quality instability. The water quality in groundwater-sourced pipes varies depending on pumping stoppage owing to power interruptions. Surface water-sourced pipe water shows seasonal variations in water quality, with occasional large deviations from the normal trends following flow interruptions.

“…Büyükuslu et al [244] examined the campus buildings of Giresun University (Turkey) and obtained an average concentration value of 193.7 Bqm −3 , which was observed to be below the recommended limits. Kuluöztürk et al [23] determined that the permissible limit value was determined to be exceeded in 10% of the examined houses in Ahlat (Bitlis, Turkey).…”

A comprehensive evaluation of the results obtained according to the measurement of radon gas in buildings and concrete, which is the most consumed material in the world after water, in accessible studies carried out in the last 40 years is the main objective of this study. The paper additionally aims to address the gap in the literature by comparatively determining which parameters affect radon–concrete and radon–building relationships. The scientific knowledge compiled within the scope of this article was presented under the main headings of radon and radon gas measurements in concrete and buildings. Radon gas, also known as the “invisible killer”, is considered the second most important cause of lung cancer after smoking (the gas is responsible for 3–14% of lung cancer cases in the world). The results determined that radon concentration limits have been applied in the range of 100–400 Bqm−3 in houses and 100–3700 Bqm−3 in workplaces. Studies conducted on the exhalation rate of radon showed that the radon exhalation rate of concrete may be in the range of 0.23–510 Bqm−2 h−1. The results of indoor radon concentration measurements revealed that values between 4.6 Bqm−3 and 583 Bqm−3 were obtained. Despite the existing literature, some researchers state that there is an urgent need for an improved and widely accepted protocol based on reliable measurement techniques to standardize measurements of the radon exhalation rate of construction materials and the indoor radon concentration of buildings.

People generally spend more than 90% of their time indoors. Exposure to radon in indoor environments can be a significant health problem. In this study, radon concentrations were measured to evaluate the health risks of employees and students in 6 faculty buildings in Afyon Kocatepe University Ahmet Necdet Sezer Campus and to calculate annual effective dose equivalents. Measurements were carried out in the Genitron AlphaGUARD PQ2000 PRO Radon Detector System which measures with active measurement method. The radon concentration values of the faculty buildings are 4.48-82.00 Bqm-3; mean radon concentrations were determined in the range of 20.64-30.91 Bqm-3. The average radon concentration of all buildings was calculated as 24.79 Bqm-3. The annual effective dose equivalents of 6 faculty buildings were determined in the range of 0.16-0.24 mSvy-1, and the average annual effective dose equivalent was calculated as 0.20 mSvy-1. The results were compared with the limit values recommended by the International Commission on Radiological Protection (ICRP) and the Turkish Atomic Energy Authority (TAEK) for radon gas concentrations in indoor environments. The measurement results of the radon concentrations and annual effective dose equivalents of the 6 faculty buildings on the ANS Campus were determined below the limit values allowed by the institutions.
