Figure 4
Dose estimation by Gafchromic film dosimetry. (a) An overexposed Gafchromic film illustrating full beam shape at the mirror focus. (b) Visualization of radiochromic film (RCF). The RCF was saturated for this exposure time (2 s) and attenuation (0.5 mm Al). Dose rate analyses were carried out for each region of approximately 80 µm × 80 µm between the two white arrows along the center of the vertical axis of the beam shown by the black arrow. (c) Dose rates at various Al attenuation levels, 0.5 mm, 1.0 mm and 2.0 mm shown in black, red and blue, respectively, along the center of the vertical axis of the beam between the two white arrows shown in (b). (d) Relative dose rate at the Al attenuation levels and positions shown in (b).
