Cyclotron radiation of both fast (Alfven waves) and slow (Bernstein) waves from a mode-conversion layer is considered to find relations between cyclotron absorption and emission in an inhomogeneous plasma. The relative emission ratios among various modes are calculated and asymmetries of emission are discussed. From relations between emission and absorption, a form of Kirchhoff's law for a mode-conversion layer is proved from general thermodynamic arguments and from the mode-conversion tunneling equation.
