What is Daughter Nuclide?
A daughter nuclide (or daughter isotope) is the nuclide produced as a result of the radioactive decay of a parent nuclide. After decay, the daughter nuclide may itself be radioactive (continuing the decay chain) or stable. The relationship is tracked in radioactive decay series (e.g., the uranium-238 decay chain ends at stable lead-206).

Nuclear medicine generators (Mo-99/Tc-99m generator — Mo-99 is parent, Tc-99m is daughter used for scans); radioactive dating (parent/daughter ratio used to calculate age); nuclear waste management; nuclear physics research
Radioactive daughter nuclides require appropriate radiation shielding and handling. Radon-222 is a radioactive daughter of radium-226 in the uranium decay chain and is a significant environmental lung cancer hazard.
