What is the nuclear product of radioactive decay called?
The products of radioactive decay are called daughter products.
Uranium-238 undergoes α-decay.
The thorium-234 in turn undergoes β-decay.
The nuclei that result from radioactive decay may themselves be radioactive.
Protactinium is also radioactive and continues a long radioactive decay chain that ends with the stable nuclide lead-206.
Thus, the decay of uranium-238 forms a whole host of radioactive nuclei.
The decay products of radioactive nuclei are called daughter products.
