“…The chemical analysis illustrated that USDS contains uranium and thorium, which is higher in the fraction 50-100 μm than in the fractions 2-10 and 10-50 μm in the cities under study. Thus, the GA may be attributed to natural radionuclides in the environment like uranium, radium, thorium and their decay products [28,29]. Increasing uranium and thorium content led to an increase inthe GA activity concentration in the USDS fractions.…”

Study of gross alpha (GA) and gross beta (GB) activity in road and surface deposited sediments were performed in various geographical areas in three Russian cities. To perform radiation measurements, new methods were applied which allow dealing with low mass and low volume dust size (2-100μm) samples obtained after the size fractionation procedure. The 2-10 μm fraction size has the highest gross beta activity concentration (GB)– 1.32Bq/g in Nizhny Novgorod (NN) and Rostov-On-Don (RND) while the 50-100 μm fraction size in Ekaterinburg. This is maybe associated with the subsistence of radionuclides that conveyed through natural processes and anthropogenic applications. The highest gross alpha activity concentration (GA) in fraction sizes was found in Rostov-on-Don city within the 50-100 μm– 0.22Bq/g. The fraction size 50-100 μmhas a higher gross alpha activity concentration than 2-10 and 10-50 μmfraction sizes due to natural partitioning of the main minerals constituting the urban surface deposited sediment (USDS). The geochemical processes that occur during the formation and transportation of USDS are reflected in the observed dependencies.Developed experimental methods of radiation measurements allowed to the extent the methodological base of urban geochemical studies.

“…Mean gross alpha and beta activities in the main course were found to be 0.095 and 0.21 Bq L −1 , respectively, being the main natural radionuclide contributions uranium, radium, and their alpha daughters for gross alpha activity, and 40 K and 226 Ra beta daughters for gross beta activity (Sanchez-Cabeza and Pujol 1998;Pujol and Sanchez-Cabeza 2000). The notable number of worldwide studies aimed at analyzing the levels of radioactivity in natural water bodies show a high variability of results, with gross alpha and beta activities ranging <0.008-0.782 and 0.021-0.816 Bq L −1 , respectively (i.e., Bozkurt et al 2007;Dueñas et al 2007;Forte et al 2007;Kücükömeroglu et al 2008;Popovic et al 2008;Selçuk Zorer et al 2009). The concentrations here reported for tap water from the Ebro River are generally in the lower range than those reported in the scientific literature.…”

This study was aimed at assessing the levels of 210Pb and 210Po concentrations as well as gross alpha and beta activities in environmental monitors from the Catalan stretch of the Ebro River (Spain), potentially influenced by the presence of sediments with high concentrations of 238U and its decay chain daughters in the Flix reservoir. The chronic daily intake of 210Pb and 210Po through ingestion and inhalation of soils was evaluated, and the derived non-carcinogenic and carcinogenic risks were characterized. The low concentration of radioisotopes in soils resulted in a negligible annual effective dose. The levels of 210Pb and 210Po were determined in various groups of highly consumed food (fish and seafood, vegetables, fruits, and rice), and their dietary intake was calculated. The annual effective dose for the adult people from food intake was estimated in 3.3×10(-2) mSv, mostly due to 210Po. Overall, the current radioactivity levels in the Catalan stretch of the Ebro River should not mean any additional health risk for the population living nearby. However, an integral assessment of the risks derived from exposure to other pollutants (e.g., metals and organochlorine compounds) jointly with radionuclides could be of great interest.

“…Uranium concentration in soil samples have been measured by two different methods (Baykara et al, 2007), besides, Kucukomeroglu et al (2008) investigated gross alpha/beta analyses in water by liquid scintillation counting (Wong et al, 2005) and in IAEA (2004) have measured radioactivity in sediments. In this type of nuclear applications, the characterization of gross alpha and beta radionuclide content (Zapata-Garcia et al, 2009) can be performed for various samples: solids, liquids, aerosols filters, etc.…”

“…The presence of radioactivity in the environment is caused by naturally occurring radionuclides (terrestrial radiation) and cosmic radiation, but also by artificial radionuclides, which have been incorporated due to fallout from nuclear accidents (Kucukomeroglu et al, 2008). Radiation is non-sensory (Herman and Thomas, 2009) and the presence of radioactivity and radioactive material shall be identified by the use of radiation detection instruments only.…”

The beta counting system uses a Geiger-Muller (GM) tube to detect the prese nce of beta contamination present in filter paper samples or in planchet samples. The counting system is enabled with a provision to count the samples at various distances from the detector to the sample position. The efficiency of the counting system is provided by the manufacturer at the time of procurement which is calibrated and tested using the standardized source. The user end has to be in conformity that the counting system responds to the radioactivity properly, since efficiency acts as the standard of comparison to check the healthiness of the detector. The paper brings out the practical experience gained while validating the efficiency of the counting system at various distances using the slit height adjustment.
