Range calculation of alpha-recoil atoms in some minerals using LSS-theory

Alpha-recoil ranges were calculated for fifteen interesting minerals, especially for naturally occurring alpha-emitters, on the basis of the simple LSS-theory. The ranges obtained from single decay process were represented as a comprehensive range expression in A units, as well as the physical ranges in μg/cm2 units. Furthermore, the total mean ranges concerning overall alpha-decaying members within each natural decay series, including the extinct neptunium series, have also been evaluated and tabulated. These calculated ranges can contribute to the interpretation of the widespread disequilibrium states in respective decay series in nature as well as in laboratory experiments.
