Radiochemistry Policies and Procedures

Disclaimer of Responsibility

The following material is intended for research purposes only. Neither Washington State University nor the United States Transuranium and Uranium Registries may be held responsible for unauthorized changes and/or use of this material.


The United States Transuranium and Uranium Registries (USTUR) began with the establishment of the National Plutonium Registry in 1968 by the Atomic Energy Commission. The program name was changed in 1970 to reflect a broader interest in transuranic elements. A similar program was created in 1978 to study the uranium decay series and was named the United States Uranium Registry. Analytical support for the registries was provided by Rocky Flats from 1968 until 1987, Pacific Northwest Laboratory from 1968 until 1978, and Los Alamos National Laboratory from 1971 until 1993. Responsibility for the Registries was transferred to Washington State University in February 1992 at which time the two registries were joined as the USTUR.

Authorship of these procedures is listed as USTUR Radiochemistry Staff. Appropriate citation of original LANL methods is included in each section. Modification and additions to LANL procedures and new procedures/methods were written by Jim Elliston, Roy Filby, Sam Glover, Cathy Grimm, Suzanne Love, Hongguo Qu, Dorothy Stuit, Gail Deckert, Sergei Tolmachev, and Fred Miller.

This manual represents the third edition of the USTUR Radiochemical Analysis Procedures Manual. All previous editions shall be immediately superseded by this edition.
