In this paper we characterize the boundedness, compactness, and weak compactness of the integration operators \begin{ align*} T_g (f)(z)=\int_{ 0}^{ z} f(w)g'(w)\ dw \end{ align*} acting on the average radial integrability spaces $RM(p,q)$. For these purposes, we develop different tools such as a description of the bidual of $RM(p,0)$ and estimates of the norm of these spaces using the derivative of the functions, a family of results that we call Littlewood-Paley type inequalities.
