The present paper is carried out to determine the Radiolumincscence and scintillation properties of Zinc Oxide (ZnO) and Zinc Oxide doped with Aluminum ZnO(Al). The samples were prepared as a disc from Powder, which prepared by US Research Nanomaterials, Inc. The samples were characterized by Multichannel Analyzer (MCA) using different radiation sources Americium-241 (241Am), Cesium-137 (137Cs), Barium-133 (133Ba) and Europium-152 (152Eu). When the thicknesses of ZnO used are 3 mm, 6 mm and 22 mm, the number of radiation counts are 344 M, 88 M, and 6.6 M, respectively by using 241Am, and 1.2 T, 6.7 M and 6.6 M respectively when using 152Eu.Two samples are used as radiation detector using ZnO(Al) 2 mm and 6 mm, in which the counts 5.96 M and 5.93 M respectively using 241Am,54 M and 5.4 M using 152Eu. The 133Ba and 137Cs was applied for 3 mm ZnO and gives 1.5 T and 6.1 M number of counts respectively. The number of counts for both the ZnO and ZnO(Al) decrease with increasing thickness of the samples. However, the luminescence and scintillation properties were observed and quantified of the prepared ZnO/ZnO(Al). And, the gamma spectrum peaks recorded were inconclusive.
