摘要：

Changes of micromechanical properties of Poly (methyl methacrylate) - PMMA which was modified by beta radiation were examined using the instrumented microhardness test. The injection molded specimens were irradiated by 0, 15, 30, 45, 66 and 99 kGy radiation doses. Micromechanical properties in micro area showed considerable decrease and creep resistance was significantly higher at middle dose.
