The radiation logarithms L-Z have been calculated within the Hartree-Fock m
odel. That the atomic form factors are different in the Thomas-Fermi and Ha
rtree-Fock models results in different values of L-Z within these two model
s. The parameter B-Z in the representation L-Z = ln(B(Z)Z(-1/3)) is constan
t in the Thomas-Fermi model, but it depends on the atomic number Z in the H
artree-Fock model. For light elements, with the exception of hydrogen, L-Z
and B-Z values are smaller in the Hartree-Fock model than in the Thomas-Fer
mi model. The most significant distinctions are observed in the region of H
e and Li and in the region of Ne, Na, and Mg-that is, in the vicinity of cl
osed shells. With increasing Z, the distinctions between the results obtain
ed within the two models decreases, but B-Z approaches the Thomas-Fermi val
ue of 183 nonmonotonically, undergoing oscillations. A similar effect is ob
served for radiative losses of electrons and muons and for the energy losse
s of muons by the production of electron-positron pairs.
