Let \(H\) be a Hopf algebra, and \(A\) a right \(H\)-comodule algebra (not necessarily with identity). The relation between the Hopf-Jacobson radical \(J^H(A)\) and the Jacobson radical of the smash product \(J(A\#H^{*\text{rat}}\)) is studied. A version of the density theorem for simple left relative Hopf modules is given.
