The optically stimulated luminescence dosimeters(OSLDs)were prepared made of Al_2O_3:C crystal.The preliminary study on dosimetry performance was carried out.The result has shown that dose background after annealing 40 min was 0.03 mGy.The 10 pieces of dosimeter were repeated by measurement for 7 times respectively,
