The use of optically stimulated luminescence (OSL) as a method for the determination of environmental radiation absorbed dose using solid state materials has become the main interest of the most great research centers. The aim of this work is to study some dosimetric characteristics of ZrO 2 to be used as a UVR dosemeter by using the OSL method. The most attractive characteristic of ZrO 2 is its very high intrinsic sensitivity to UV radiation. Optical characteristics of ZrO 2 were also studied. OSL typical decay was obtained. OSL response of ZrO 2 samples as a function of irradiation time was linear in the range of 30-1000 s. Experimental results showed that ZrO 2 exhibit attractive characteristics which make it suitable for UV dosimetry applications.
