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.

Application of Liquid-Liquid Extraction Techniques in the Bioassay of Np, Pu, Am, Cm, Cf.

DE83750936

Publication Date	1982
Personal Author	Widua, L.; Schieferdecker, H.
Page Count	14
Abstract	The necessity of a bioassay when handling transuranium elements calls for detection of these nuclides in the low-level range. The extraction techniques used for this purpose must be suitable for assay in different organic matrices. The separation is discribed for the detection of Np/Pu and Am/Cm/Cf in biological material (urine, feces, blood, autopsy, nose swabs) and the specific problems of processing and measuring technology are discussed. The detection limit of the method is 1,85 mBq/sample (50 fCi/sample). (ERA citation 08:051759)
