Radioactive material, excepted package-instruments or articles

A radionuclide (radioactive nuclide, radioisotope, radioactive isotope, or unstable isotope) is a nuclide that is unstable and known to undergo radioactive decay into a different nuclide, which may be another radionuclide (see decay chain) or be stable. Radioactive decay is a random process at the level of single atoms: it is impossible to predict when one particular atom will decay. For a collection of atoms of a single nuclide, their average decay rate can be measured, and its half-life (t1/2) calculated. Half-lives vary by 55 orders of magnitude and have no known limits Wikipedia
