Radiometric dating problems worksheet
If the mineral contained 1 part per million Parentium-123 and 3 parts per million Daughterium-123, we could be sure all the Daughterium-123 was originally Parentium-123.
In other words there was originally 4 parts per million Parentium-123 and 0 parts per million Daughterium-123.
This is the only way Parentium-123 decays, and there is no other source of Daughterium-123.
Furthermore, Parentium and Daughterium are so different in chemical properties that they don't otherwise occur together.

Rubidium-strontium dating is more robust, and uranium-lead dating can survive fairly significant metamorphism without resetting.
If the decay constant is very small, even tiny amounts of contamination by other radioactive materials can be very significant.
So accurate determinations require very pure samples, very accurate and selective detectors, or both.
If there were such a pair of isotopes, radiometric dating would be very simple.
We could be sure that a mineral containing parentium originally had no daughterium.
