This paper starts from the premise that radioactive material, generated as a by-product of the British nuclear industry, already exists in significant quantity. The question of what should be done with this material therefore needs to be answered, even if no more of it is created. Whether the industry should continue producing radioactive waste is a legitimate question, and one which raises sig...

Nineteen different commercially available samples containing naturally occurring radioactive materials (NORM) (i.e., natural uranium, thorium, radium and potassium) were investigated, including zircon sand, cat litter, roofing tiles, ice melt and fertilizer among others. A large variation in isotopic composition was observed across the measured samples. As a result of this observation, a need w...

BACKGROUND The aim of this study was to provide a scientific method based on Geographical Information System (GIS) regarding all sustainable development measures to locate a proper landfill for disposal of hazardous wastes, especially industrial (radioactive) wastes. METHODS Seven effective factors for determining hazardous waste landfill were applied in Qom Province, central Iran. These crit...

Since the world's first disposal of radioactive waste in Oak Ridge, Tennessee, in 1944, considerable experience has been acquired in the field. The first disposal site — intended for "actively contaminated broken glassware or materials not sufficiently clean to be used in other work" — was a simple trench filled with unconditioned waste located on the Oak Ridge site. Similar approaches were ado...

espite long-standing public concern about the safety of nuclear energy, more and more people are realizing that it may be the most environmentally friendly way to generate large amounts of electricity. Several nations, including Brazil, China, Egypt, Finland, India, Japan, Pakistan, Russia, South Korea and Vietnam, are building or planning nuclear plants. But this global trend has not as yet ex...

Solid state fermentation was carried out using various agro- industrial wastes with the best amylase producing strain isolated from soil. Different physicochemical conditions were varied for maximum enzyme production. The strain produced about 5400 units/g of amylase at 1:3 moisture content, 20% inoculum, after 72 h of incubation with Mustard Oil seed cake as the substrate. The optimum temperat...
