Radioactive elements whose nuclei are unstable and atoms of such elements emit `alpha`-particles or `beta`-particles along with the `gamma`-rays. Due to emission of `alpha`-particles or `beta`-particles, atomic number and atomic mass are changed.
We cannot speed up or slow down this process by any physical or chemical change. It means we cannot affect radioactivity by changing temperature or pressure.
Radioactivity is a spontaneous process of nuclear disintegration.
Lead is heaviest stable atom. In fact all radioactive elements are finally converted into lead.
