Figure 5
Peak height growths in visible absorption spectra at 604 nm (solid circles) and 582 nm (solid squares), relative to the isosbestic point of 630 nm, versus dose following irradiation with (a) 10, (b) 13.8, (c) 17.7 and (d) 30 keV X-rays, respectively. Exponential functions (red and blue solid lines), with the exponential constants [d0 (kGy)] shown in the figures, were fitted to the data. |
