Paper MANAGEMENT OF SPENT SEALED RADIATION SOURCES
Spent or disused sealed radiation sources—no longer needed sources—may represent a risk of radiological accident or may be a target for criminal acts in countries where final disposal options are unavailable and where an increasing number of sources are being kept in extended storage. In developing countries, thousands of radium needles, teletherapy sources, oil well logging neutron sources, an...
متن کاملSafe Management of Spent Sealed Radiation Sources and Radioactive Waste in Bangladesh
Bangladesh is committed to the peaceful use of atomic energy and has signed all protocols and additional protocol of the International Atomic Energy Agency (IAEA) in this regards. Bangladesh is operating nuclear facilities using radioisotopes, sealed radioactive sources (SRS) and generating radioactive wastes including spent SRS. This paper mainly focuses on the safe management of spent SRS gen...
متن کاملEfficacy of incorporating spent seaweeds in aqua feeds as a nutritional source
Spent biomass of different seaweeds such as Sargassum wightii, Turbinaria conoides, Padina tetrastomata and Ulva lactuca were evaluated for the nutritional benefits in aqua feeds. Basic nutritional value, of seaweeds contains a number of pigments, defensive and storage compounds, and secondary metabolites that could have beneficial effects in farmed fish. Only a small fraction of algal species ...
متن کاملThermal Performance of Jet Impingement with Spent Flow Management
The present study proposes novel micro-jet impingement heat sink with effusion holes for flow extraction. The design consists of impingement nozzles surrounded by multiple effusion holes to take away the spent fluid. A three-dimensional numerical model is used for steady, incompressible, laminar flow and conjugate heat transfer for the performance analysis of the proposed design. The computatio...
متن کاملTHE SpEnt METHOD FOR LOSSY SOURCE CODING †
At present, the most successful methods for lossy source compression are sample-function adaptive coders. Prominent examples of these techniques are the still image compression methods utilizing wavelet expansions and tree structures, such as the zero-tree method or the SPIHT algorithm, and variable rate speech coders that allocate bits to parameters within a frame based upon the classification...
