The parent nuclide always has a shorter half-life than the daughter nuclide.
If the half-life of the parent nuclide is 50 times greater than the half-life of the daughter nuclide, the equilibrium portion of the activity curve is basically flat and is categorized as “secular” equilibrium.
The parent nuclide is less tightly bound to the column than the daughter nuclide
None of the above
Transient equilibrium in which the parent half-life is 10 to 100 times that of the daughter.
Secular equilibrium in which the parent half-life is more than 100 times that of the daughter.

Mixtures of radionuclides must appear in order of decreasing radiotoxicity as space permits
The activity must be in SI units of Becquerel (Bq, MBq, GBq)
The Transport Index (TI), defined the maximum dose rate in mrem/hr at 1 meter from the package surface, is required only on Yellow II and Yellow III Type A packages.
All Type A packages (White I, Yellow II, Yellow III) require a Transport Index
