Radiative decays {upsilon}(1s){yields}{gamma}({eta}{sup '},{eta}) are studied by an approach which has successfully predicted the ratio ({gamma}(J/{psi}{yields}{gamma}{eta}{sup '})/{gamma}(J/{psi}{yields}{gamma}{eta})). Strong dependence on quark mass has been found in the decays (J/{psi},{upsilon}(1s)){yields}{gamma}({eta}{sup '},{eta}). Very small decay rates of {upsilon}(1s){yields}{gamma}({eta}{sup '},{eta}) are predicted.
