Investigation into Polyurethane at Varying Dose Rates of Ionizing Radiation for Clinical Application

Figure 3

Field-emission scanning electron microscopy of polyurethane films sputter coated with gold at (a) 0 Gy·min⁻¹, control (b) 3.2 Gy·min⁻¹, and (c) 833 Gy·min⁻¹ dose rates. Scale bars represent 10 µm.
