National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Abstract	The rapid decontamination of accidental liquid wastes containing various radioactive nuclides is important from the standpoint of radiation exposure reduction and radiation protection. For this purpose, the development of multi-functional microcapsules with high uptake ability for different radioactive nuclides is required for this treatment. In order to remove radioactive nuclides from the waste solutions, a large number of selective inorganic ion-exchangers and extractants have been developed. Since most of these materials are very fine powder or oily, they have some difficulties in handling for the practical applications.
