A simple unifying mass matrix is presented for the three active and one sterile neutrinos {nu}{sub e}, {nu}{sub {mu}}, {nu}{sub {tau}}, and {nu}{sub s}, using an extension of the radiative mechanism proposed some time ago by Zee. The total neutrino-oscillation data are explained by the scheme {nu}{sub e}{leftrightarrow}{nu}{sub s} (solar), {nu}{sub {mu}}{leftrightarrow}{nu}{sub {tau}} (atmospheric) and {nu}{sub e}{leftrightarrow}{nu}{sub {mu}} (LSND). We obtain the interesting approximate relationship ({Delta}m{sup 2}){sub atm}{approx_equal}2[({Delta}m{sup 2}){sub solar}({Delta}m{sup 2}){sub LSND}]{sup 1/2} which is well satisfied by the data. {copyright} {ital 1998} {ital The American Physical Society}
