| Abstract | In Thailand, 98.5% of the imported X-ray films are used for medical services. After the developing process, approximately 55–65% of metallic silver still remains on the developed X-ray films. The used films are practically kept at the hospitals for record-keeping purposes for 5–10 years, while the developing agents are reused at minimal twice. The discarded films and the spent (fixer) solution are normally sold to waste dealers prior to their delivery to waste processors for silver recovery. To recover silver, typically, the used films are chemically leached; the spent solution is processed by electrolysis technique. Nevertheless, the recovery processes also generate toxic chemical wastes, which are commonly spilled or discharged into the environment without any proper treatment and disposal. The dealers for X-ray waste are one of the major stakeholders who are apparently exempted from state control and regulations; but, depending on its size and capacity, the processors must have a factory-operating permit. It appeared that the key regulators of X-ray waste are the Ministry of Industry and the Ministry of Public Health. In this study, the monitoring and tracking of silver-contaminated wastes were strictly carried out from the generation points to their ultimate disposals. A fact sheet of the management of X-ray waste has been proposed. |

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.
