Abstract：The radiation shielding and magnetic properties of rare earth/polymer composites were reviewed with 10 references. The rare earth/polymer composite could make up the feeble absorbing area in the application of X ray shield and could demonstrate strong hot neutron absorbing ability when the rare earth content was high enough. The composites also had strong paramagnetism.The feasibility of preparing magnetic and magnetic intelligence materials by rare earth/polymer composites Was proposed.
