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...

Perhaps the most important single problem arising from the increasing use of atomic energy for peaceful purposes is how to dispose of the growing amounts of radioactive waste. Many of its complex aspects were discussed at the scientific conference on the disposal of radioactive waste held by IAEA in Monaco from 16 to 21 November 1959. The conference was organized jointly with UNESCO, with the c...

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...

The management of municipal solid wastes (MSW) in Latin America is, and traditionally has been, a primary responsibility of local governments. In a large percentage of medium-size municipalities in the region, the management of MSW may use between 30% and 50% of the total municipal budget. The management of solid wastes is a complicated process that not only requires the proper selection and ap...
