The percentage circular polarization is calculated for all four maser emission lines representing the ground state of the OH molecule. The populations of the Zeeman sublevels are assumed to have a Boltzmann distribution. The principal lines should exhibit strong circular polarization, but not the satellite lines. Estimates are given for the range in magnetic field strength, OH density, and kinetic temperature in an interstellar cloud such that the circular polarization of OH radio sources would be observable.
