| Abstract | River sediments from eight different sites of the coast of Calabria, south of Italy, were sampled to determine natural radioactivity and metal concentrations, in order to assess any possible radiological hazard, the level of contamination and the possible anthropogenic impact in the area. Gamma and X-ray fluorescence (XRF) spectrometry were employed and results of this study show that the mean activity concentrations of radium (in secular equilibrium with uranium) ranged from 15.1Bq/kg to 26.7Bq/kg, that of thorium from 21.8Bq/kg to 48.3Bq/kg and that of potassium from 541.3Bq/kg to 1452.2Bq/kg. In terms of mean mass concentrations, XRF analysis revealed that uranium was lower than 1.5ppm (minimum detectable value), thorium ranged from 6.1ppm to 10.3ppm while potassium ranged from 2.5% to 4.4%. The degree of sediment contaminations were computed using an enrichment factor (EF) and geoaccumulation index ( I $_{geo}$ for some potential hazardous elements. Results suggested that enrichment factor and geoaccumulation values of Pb and Mn were greatest among the studied metals. The study revealed that on the basis of computed indexes, the eight investigated rivers can be classified as no polluted ones. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
