In this work, we systematically study the two-proton($2p$) radioactivity half-lives using two-potential approach while nuclear potential is obtained by Skyrme-Hartree-Fock with Skyrme effective interaction of {SLy8}. For true $2p$ radioactivity($Q_{2p}$ $>$ 0 and $Q_p$ $< $0, where $Q_{2p}$ are released energy one-proton two-proton radioactivity), standard deviation between experimental our the...

naturally occurring radionuclide of terrestrial origin (also called primordial radionuclide) are present in various degrees in all media in the environment, including the human body itself. their concentrations in environment decrease continually by decaying. the main objective of this study is to evaluate the radioactivity levels and health risks due to terrestrial radionuclide in soil of yal...
