Radiation of gravitational waves in the case of a nonvanishing graviton mass

An expression, which is also valid in the relativistic case, is obtained for the intensity of radiation of massive gravitons by anЁarbitrary source. It is shown that the expression is positive definite and that only graviton states with spin 2 contribute to it; the state with spin 0 does not contribute to the radiation. In the case of a spherically symmetric source, only the state corresponding to zero spin projection of the graviton onto the momentum is radiated.
