Emanometry Radium Radon Ingestion dose a b s t r a c t Radium is naturally occurring radioactive element in the earth's crust. It is chemically similar to calcium and absorbed from soil by plants, passed up the food chain to humans. The occurrence and the distribution of radioactivity in water depend on the local geological characteristics of the source, soil, rock and other factors that control the occurrence and distribution of radionuclides in ground water and the hydro geological condition and the geochemistry of radionuclides. Activities of the naturally occurring radionuclides 226 Ra and 222 Rn were determined in natural ground water of the Mandya district, Karnataka State, India. The concentration of 222 Rn in borewell water varies form 6.44 ± 0.20 to 44.83 ± 0.54 Bq l À1 with geometric mean 16.42 ± 0.31 Bq l À1 . Higher radon concentrations were observed at Yettaganahalli and Mandya city. 226 Ra concentration varies form14.26 ± 0.32 to 81.06 ± 0.99 mBq l À1 with geometric mean 27.61 ± 0.43 mBq l À1 . It is observed that the radon concentration is high in ground water around the granitic rock exposures and similarly observation of high values of radon is reported in sheared gneiss which covers major portion of the Mandya district to phyllites and schists. The total dose due to ingestion and inhalation varies from 26.31 to 178.53 mSv y À1 with a geometric mean of 65.94 mSv y À1 , which is below the prescribed dose limit of 100 mSv y À1 by WHO.

“…Beitollahi et al (2007) clarified that the higher radon levels (145-2731 Bq/l) in Iran hot springs are derived from travertine deposits (CaCO 3 ). In another study performed with waters from Etna Montain (Italy), while radon concentration vary from 1.4 to 12.7 Bq/l, radium concentrations found up to 12.0 Bq/l (Kozlowska et al 2009). …”

The radioactivity levels ( 222 Rn and 226 Ra) and physico-chemical properties of geothermal waters from two spas of Bayındır are investigated. Radon and radium measurements were made with collector chamber method. The radon concentrations range from 3.0 to 13.3 Bq/l, whereas the radium varies from 0.35 to 1.71 Bq/l. It has been observed that radon levels increase in winter and decrease in summer. The 222 Rn/ 226 Ra ratio was found to range from 4.91 to 30.53. Physico-chemical properties of water samples were also analysed. Water samples have considerably stable total dissolved solids values, slight acidity, low electrical conductivity, and temperature (42-48°C).

This variability is linked to different Eh-pH conditions that in some cases include the occurrence of U scavenging by Fe oxides/hydroxides (Aiuppa et al 2000b).…”

In view of the establishment of quality standards for uranium in drinking water by the European and Italian authorities, we report a comprehensive overview of the Italian situation regarding uranium concentrations in natural waters. More than 3100 data on waters all over Italy are reviewed in addition to new data for Latium Region (Central Italy) where relatively high concentrations in rocks are long been known. Our study evidences that uranium in bedrock is not the main factor ruling uranium presence in fresh and groundwater, indicating that redox conditions as well as bicarbonates and silicates control solution equilibria and accordingly the uranium content in waters. At present, and considering the provisional guideline value of 30 lg/L established by [WHO (2012) Guidelines for Drinking-Water Quality. World Health Organization, Geneva], no critical situation is envisaged in Italy, but this can be overruled if lower limits will be actually imposed. There is also a need of further studies on uranium speciation in water and of wider epidemiological studies to assess its real toxicity to overcome the uncertainties that have so far hampered the definition of reliable water quality standards.
