Plots of K against E demonstrating that K is inversely proportional to E. The circles, squares and triangles denote IC1, IC2 and IC3, respectively. The open and closed marks are data for 10 and 15 keV Xrays, respectively. The lines with crosses denote the calculated K values using equation (7), in which the value of 3.02 × 10^{10} V m C^{1} was used for (ICRU, 1982). The charge per pulse ranged from 0.4 to 1.7 pC.
