Radioactive equilibrium: 99Mo/99mTc decay characteristics

• We examine the 99Mo/99mTc radioactive equilibrium mixture decay.
• Specific features of this decay are underlined.
• Absolute intensities of all emissions have been evaluated.
• Normalization factor has been deduced using intensity balance relations.
• The literature available by 2013 has been included.

Within the Decay Data Evaluation Project, as an example of a radioactive equilibrium with isomer, the 99Mo/99mTc equilibrium mixture decay characteristics are examined. The results of a new decay data evaluation are presented for 99Mo/99mTc decay to nuclear levels in 99Tc. These evaluated data have been obtained using information published up to 2013.
