  The total photodisintegration cross sections of three-body nuclei are
calculated with semirealistic NN potentials below pion threshold. Full final
state interaction with Coulomb force is taken into account via the Lorentz
integral transform method. The experimental total cross sections are well
described and the sum rule $\sigma_{-1}(^3$H) agrees with elastic electron
scattering data. The calculated ^3He polarizability is 0.15 fm^3.
