The revised deflnition of radioactive naterial unsuitable for dumping at sea has been fornulated, ln parE, in qualitative terns and, in part, in numerical terrns, based on the princj.ples of radiation protection and sclentific modelling.

analysis: This text appears to be discussing international agreements and regulations related to the dumping of radioactive waste at sea. It mentions the London Dumping Convention, the Convention on the Law of the Sea, and the 9th and 10th Consultative Meetings. The text also references scientific modeling and radiation protection principles. Given the technical and regulatory nature of the content, it is likely that the text falls under the category of Natural resources and environment or Science and technology.
