Decay Data Evaluation Project (DDEP): Updated decay data evaluations for (24)Na, (46)Sc, (51)Cr, (54)Mn, (57)Co,...

Area of Science:

• Nuclear Physics
• Radiochemistry
• Metrology

Background:

• The international scientific community relies on accurate radionuclide decay data for various applications.
• Previous Decay Data Evaluation Project (DDEP) evaluations were published in 2004.
• Continuous updates are necessary due to new experimental data and analytical methods.

Purpose of the Study:

• To present updated DDEP evaluations for the decay characteristics of specific radionuclides.
• To incorporate experimental data published between 2004 and 2014.
• To compare new evaluations with previous results.

Main Methods:

• Systematic review of experimental data published from 2004 to 2014.
• Inclusion of new compilations, analyses, and corrections.
• Comparative analysis of updated evaluations against prior DDEP results.

Main Results:

• Updated decay data evaluations for radionuclides including sodium-24 (Na-24), scandium-46 (Sc-46), chromium-51 (Cr-51), manganese-54 (Mn-54), cobalt-57 (Co-57), iron-59 (Fe-59), yttrium-88 (Y-88), and gold-198 (Au-198).
• Incorporation of recent experimental findings and refined analytical approaches.
• Quantification of differences between updated and previous DDEP evaluations.

Conclusions:

• The updated DDEP evaluations provide a more current and accurate set of radionuclide decay characteristics.
• The study highlights the importance of ongoing data evaluation in nuclear science.
