Detailed explanation-1: -Yes, the decay half-life of a radioactive material can be changed. Radioactive decay happens when an unstable atomic nucleus spontaneously changes to a lower-energy state and spits out a bit of radiation. This process changes the atom to a different element or a different isotope.
Detailed explanation-2: -As the nucleus emits radiation or disintegrates, the radioactive atom (radionuclide) transforms to a different nuclide. This process is called radioactive decay. It will continue until the forces in the nucleus are balanced.
Detailed explanation-3: -Elements that emit ionizing radiation are called radionuclides. When it decays, a radionuclide transforms into a different atom-a decay product. The atoms keep transforming to new decay products until they reach a stable state and are no longer radioactive.
