The GJ-2 electron accelerator (made in China, Sanghai) was put into operation at the Centre for Application of Isotopes and Radiation in Jakarta, Indonesia. In the course of the commissioning of the machine its main technical parameters were measured under different operating conditions. The electron energy was determined applying both wedge and stack methods at 1.5 and 2.0 MeV. The scanning width and homogeneity and the dose distribution in reference product were measured with film dosimeters. Nominal dose measurements were performed using alaninepolyethylene dosimeters produced at CAIR, ethanol-chlorobenzene dosimeter solution and FWT-60 film dosimeters. The applicability of polystyrene calorimeters designed for low electron energies at Risø National Laboratory was also tested for nominal dose determination.
