A gamma-ray polarimeter utilizing Compton scattering as the analyzing process is described. Measurements of the polarization-direction correlations of the gamma-rays emitted in the disintegration of ${\mathrm{Sc}}^{46}$, ${\mathrm{Co}}^{60}$, ${\mathrm{Rh}}^{106}$, and ${\mathrm{Cs}}^{134}$ are reported.
