Hyperfine structures of the triplet n3S-states in the four-electron Be-atom(s) and Be-like ions are considered. It is shown that to determine the hyperfine structure splitting in such atomic systems one needs to know the triplet electron density at the central atomic nucleus ρT(0). We have developed the procedure which allows allows one to determine such an electron density ρT(0) for arbitrary four-electron atoms and ions.
