In 1983, the Preparatory Commission for the International Sea-Bed Authority and the International Tribunal for the Law of the Sea appointed its officers, decided upon its structure and adopted a programme of work. In July of the previous year, the US Government announced that it would not sign the Convention on the Law of the Sea and thus would not participate in the deliberations of the Preparatory Commission. As part of the Texts adopted, Resolution II establishes a scheme for the Protection of Pioneer investment pending the entry into force of the Convention. This scheme is predicated on the philosphy embodied in the Convention in respect of the establishment of a resource policy for the development of sea-bed mineral resources and takes into account its basic component, the limitation of production. This article investigates the impact of future sea-bed mineral development on the affected economies of developing land-based producer states. It also reviews the mechanisms to be utilized to mitigate against possible adverse impacts and attempts to assess the extent to which these resources may be exploited in the medium term. 相似文献

In this paper, results are reported on the concentrations and activity ratios of 137Cs, 239+240Pu and 238Pu in soils, lichen and bottom sediments collected at the peaceful underground nuclear explosion sites "Craton-3" and "Crystal" (Republic of Sakha (Yakutia), North-East Siberia). At the "Craton-3" site, 239- 240Pu concentrations in the range 6.2 mBq/g to 5.9 Bq/g in surface soils (0-5 cm) and 239+240Pu concentrations up to 7.4 Bq/g in lichen were observed. The 137Cs concentration in measured soils range from 0.52 to 216 Bq/g for the near-plume and from 1.65 to 21.5 Bq/g for the far-plume. In lichen, 137Cs concentration varied from a global background level up to 251 Bq/g. Radioactive contamination at "Crystal" demonstrates an extremely irregular distribution of 239,240Pu and 137Cs in environmental samples taken at locations within 150 m radius of the site. Further work on compiling detailed maps of radioactive contamination of the territory around "Craton-3" and "Crystal" is discussed. 相似文献
