In March 2002, the Department of Energy headquarters standardized all DOE inventory reporting to one source - The National Nuclear Data Center Wallet Cards at Brookhaven National Laboratory. The NNDC has agreed to maintain the integrity of the PDF version of the January, 2000 edition of the Nuclear Wallet Cards. This version will be "frozen" in time and will be the official, DOE, reference source for nuclear decay information until replaced by a new DOE standard.
The current location of the PDF version of the January, 2000 edition Nuclear Wallet Cards is http://www.nndc.bnl.gov/wallet/pdf_files/wallet-2000.pdf.
