Nuclear Decay Data in the MIRD Format To NNDC To NNDC

Tables of nuclear and atomic radiations from nuclear decay and decay scheme drawings will be produced in the Medical Internal Radiation Dose (MIRD) format from the Evaluated Nuclear Structure Data File (ENSDF) for the specified nuclide. Output may be either HTML-formatted tables and JPEG drawings, PostScript tables and drawings, or PDF tables and drawings.

(e.g., 99Tc or Tc-99)
Output Format:

Nuclear decay data are available in other formats, along with the ability to specify retrieval criteria, in the Decay Radiation Search of NuDat. Documentation of the calculational methods and auxiliary data used in producing these tables may be found in “The Program RADLST” (T.W. Burrows. Brookhaven National Laboratory Report BNL-NCS-52142, February 29, 1988)
