Abstract
The applicability of using the radio-luminescence of Si-doped Gallium Nitride GaN(Si) for the detection of alpha particles was investigated. Different Americium-241 sources with different activities were used. The results showed that GaN(Si) has an excellent linearity with exposure time and activity. The uncertainty of the repeatability test was found to be less than 2%. In addition, the performance of GaN was compared with ZnS(Ag). Results showed that GaN(Si) is more appropriate for wide range of activities and has no saturation like the response of ZnS(Ag)..
