This internship offered the opportunity to work on the IAEA’s Marine Information System (MARiS), a publically accessible database of marine radioactivity measurements. MARiS is fed with data from GLOMARD, an in-house relational database into which data is uploaded after it is verified and quality controlled. MARiS is in a phase of development and expansion and the intern will become involved in activities that are synergistic to this endeavour.Initial tasks would be to become familiarized with the GLOMARD database and the MARiS web interface, learn how to validate and prepare data for upload to GLOMARD, and offer suggestions for improvement. There will be a focus on Fukushima related datasets as these are of highest priority for the Agency and will allow the intern to become familiar with the nuances of topic specific datasets. Newly incorporated data will be displayed in a geospatial context to show the distribution of radioactive contaminants from Fukushima in the seas off Eastern Japan. One approach for doing this is by using the Generic Mapping Tools (GMT), which is currently available in NAEL for generating geospatial maps using an internal webpage interface. There will be the opportunity to work on and develop the existing GMT software code for this internal webpage to improve and add to the current mapping functions.

Education in Environmental Engineering & Sustainable Infrastructure master program has provided a strong foundation in understanding physical and chemical processes in environmental dynamics, waste management, wastewater treatment, quantitative hydrogeology,and many other interesting subjects.

GLOBAL CYCLE OF GALLIUM PRODUCTION, USE AND POTENTIAL RECYCLINGQuantification of main global cycles of gallium, production, consumption and end of life products, also investigation about recycled gallium and potential recycling possibilities are the mainsprings for this study. Initially making a qualitative substance flow for gallium is done by patterning after other metal cycles with regards to exclusive characteristics of gallium flows itself. Data bases like USGS and World mining data are used to achieve most important amounts of gallium production, main gallium consumptions and end of life products that contain gallium. Moreover a categorization of available data and designation of an uncertainty level with regard to data source and reliability of data source is performed. Then a quantitative model is designed by applying STAN; software for subSTance flow Analysis which is implemented to shape gallium material flow analysis according to the Austrian standard ÖNorm S 2096 and meanwhile major applications, concentration of gallium in different products, waste flows, landfills and present recycling technologies considered. STAN calculated other unknown flows with their uncertainties. The quantification of gallium flows is implemented with two methods; Top-Down and Bottom-Up analysis, even if the required data for bottom-up analysis is so limited. Finally STAN model give an overview on main gallium flows. Main gallium flows are primary production and refined gallium production in production process and ICs fabrication, LED, PV and recycled new scrap flow in manufacturing process. Remarkable amount of gallium is collected as stock in consumption process. As the cost of recycling is not economically justified, current gallium recycling facilities are limited. Significant recycled gallium portion is originating from new scrap which is formed through manufacturing process.
