The reduction in the DPPH concentration is a measure of scavenging activity. After the application of gamma radiation at doses 0.3, 1.0, and 3.0 kGy, the pattern of change in scavenging activity are shown in Fig. 3. At 1.0 and 3.0 kGy
radiation dose, the activity was increased by 3.9% and 3.2% compared to that of the control
