The Los Alamos National Laboratory Research Library has obtained permission from the National Academy of Sciences to scan and produce PDF files of these out-of-print publications which are invaluable to radiochemists and researchers in other fields such as physics, biochemistry, and medicine.

The Research Library extends special thanks to the technical staff of CST Division at Los Alamos National Laboratory for the loan of copies of many volumes in this series for scanning and for providing funding for this project.
