The rational parts are found in A251629.
See the comments, examples and a link in A251629 for details. The squared radii R2(n) for lattice point hitting circles centered at any of the lattice points of the Archimedean tiling (4,8,8) are integers in the real quadratic number field Q(sqrt(2)), namely R2(n) = A251629(n) + a(n)*sqrt(2), n >= 0.
