“…Aerosol samples were collected on filter papers (Whatman 41, 15 cm×25 cm in diameter, relative efficiency for deposited dust 82%) by constant flow rate samplers (air flow 40-60 m 3 h -1 , average daily volume in the interval 720-1440 m 3 ). The filter papers were then ashed at temperatures below 400 °C and a monthly composite sample containing 30-31 daily filters was formed (volume in the interval 30×10 3 -60×10 3 m 3 ) [18]. The activity of 7 Be, 210 Pb and 137 Cs was determined on a HPGe detector (Canberra relative efficiency 20%) by standard gamma spectrometry.…”

7Be, 210Pb and 137Cs activity concentrations in ground level air at five monitoring stations (MS Vinca, Zeleno Brdo, Zajecar, Vranje and Zlatibor) in Serbia were determined during the period from May 2011. to September 2012., as part of the project monitoring of Serbia. Activity of the radionuclides in air was determined on an HPGe detector (Canberra, relative efficiency 20 %) by standard gamma spectrometry. Concentrations of cosmogenic 7Be, ranged from 1.5 to 8.8 mBq m-3 and exhibit maxima in the spring/summer period. The maximum concentrations for 210Pb were generally obtained in the fall for all investigated locations, and concentrations were in range 3.6 - 30 ? 10-4 Bq m-3. The activity concentrations of anthropogenic 137Cs in ground level air, during the observed period, were at level 0.3 - 8 ?Bq m-3. The variations in 7Be/210Pb activity ratio for the investigated stations are also presented. [Projekat Ministarstva nauke Republike Srbije, br. III43009]

“…Analyses of radionuclides in environmental samples are carried out daily in many laboratories. These data are used for a variety of purposes including environmental surveys (Popović et al, 2007) and dose assessment in man and the environment, the establishment of standards of regulatory guides (Poms and Astley, 2011), and in decision making on economic, legal and health aspects (Betti and Aldave de las Heras, 2004). It is important to assure the accuracy and precision of the analysis results to guarantee that decisions are based on reliable results.…”

To assure that radiological monitoring is reasonably valid, organisations performing such measurements have found it necessary to establish quality assurance (QA) and quality control (QC) programs. These programs are needed to identify deficiencies in the sampling and measurement processes. In addition, validation of the monitoring aims to prove whether the results are acceptable. The major aim of QA and QC in analytical laboratories is to address measures used to verify the validity of the final results. In the document ISO 17025 the requirements on how to achieve QA and QC in analytical laboratories is described. All proposed measures for QC/QA are implemented in the Radiation and

Due to changed atmospheric concentrations of trace elements, their availability and cycling has changed, too. Numerous studies showed that trace metals as persistent, widely dispersed and interacting with different natural components, cause threat to human health and environment (Seinfeld & Pandis, 1998). Trace elements in urban areas (such as Cu, Zn, and Pb) are mainly emitted by traffic, including exhaust emissions and vehicle wear products (Harrison et al., 2003). Even though the use of leaded gasoline has been drastically reduced, our understanding of the effects of whole lead emission to air is far from sufficient (Van der Gon & Appelman, 2009). As reported recently, though atmospheric Pb had declined by a factor of 7 from 1980 to 2007, atmospheric deposition is still recognised as a major pathway of Pb to vegetation and topsoil (Hovmand et al., 2009). Since it offers a practical approach for monitoring deposition of atmospheric trace elements on the surface environment (Azimi et al., 2003; Tasić et al., 2008), collection of atmospheric deposition using bulk sampling devices has been extensively used. However, instrumental studies on atmospheric contamination are often limited by high cost and difficulties in carrying out extensive monitoring surveys in time and space, and do not offer reliable information about an impact of atmospheric pollutants on the living systems. Among the naturally occurring radionuclides in air, beryllium-7, radon and its short lived progenies are most significant, while caesium-137 is of major interest among the fission products. Long-lived radionuclides, potassium-40, uranium and thorium, found in 6 www.intechopen.com
