%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
This compilation contains, for those radionuclides tabulated, all necessary data for qualitatively and quantitatively measuring photon emitting radionuclides as well as conducting activation analysis using gamma-ray spectrometry.

4. METHODS: METHOD OF SOLUTION

6. TYPICAL RUNNING TIME

To compile NUCDAT and edit the entire DECAYGAM library requires 1 minute on the IBM 360/91. DKDATA sample problem requires 18 sec. on IBM 360/75.

8. RELATED AND AUXILIARY PROGRAMS

NUCDAT - will read data from magnetic tape or cards, generate a new  data tape from cards and produce a listing in two main tables. Table I is an unmodified listing of the input information arranged according to increasing atomic number. For each atomic number entries are arranged by increasing mass number. Table II, whose listing is optional, consists of a sorted list of the most intense gamma-rays arranged according to increasing energy. Listed also in Table II along with each gamma-ray energy, is the radionuclide to which the gamma ray belongs, its half-life, type of radionuclide, and energies and intensities for several of the most intense gamma rays emitted by the radionuclide. These associated gamma rays are arranged by decreasing intensity to enable gamma-ray spectroscopists to easily compare lines in spectra with the most intense tabulated energies and thus rapidly identify the components of unknown spectra.
DKDATA - is a subroutine which returns to the calling program information concerning the gamma-ray decay characteristics of a nuclide of specified atomic number and mass. This data is initially  read from DLC-19 on first entry to the subroutine, and the pertinent data for all nuclides of interest are stored for use in subsequent calls.
