Radioactive isotope samarium-153 bụ isi akụkụ nke ọgwụ samarium (153Sm) lexidronam (Quadramet), nke na-egbu mkpụrụ ndụ cancer na ọgwụgwọ nke ọrịa cancer akpa ume, ọrịa prostate, ọrịa ara ara, na osteosarcoma. The isotope, samarium-149, bụ ike neutron absorber na ya mere agbakwunyere mkpara njikwa nke nuklia reactors. A na-eji Sameria oxide eme ihe pụrụ iche nke iko infrared-adsorbing na cores nke carbon arc-lamp oxide electrodes na dị ka ihe na-eme ka akpịrị ịkpọ nkụ na mmiri gwụ nke ethanol.
