Summary: Let \(R\) be a ring with identity and \(M\) be a unital right \(R\)-module. A nonzero submodule \(N\) of \(M\) is called a second submodule if \(N\) and all its nonzero homomorphic images have the same annihilator in \(R\). The second radical of a module \(M\) is defined to be the sum of all second submodules of \(M\). In this paper we give some results concerning second submodules and attached primes of a module and we study the second radical of a module in some cases.
