उत्तर
The substance's rate of decay and the type of radiation it emits are unaffected by any physical or chemical changes, including variations in temperature and pressure, extreme heating, freezing, the effect of strong electric and magnetic fields, chemical treatment, oxidation, etc.
This demonstrates unequivocally that the orbital electrons, which are susceptible to such alterations, cannot be the cause of the radioactive event. Thus, the nucleus should be the source of radioactivity. The phenomenon of radioactivity is thus nuclear.
