The plot of shear rate value versus radiation dose. The shear rate value was taken from the study carried out by increasing the shear rate and monitoring change in viscosity. The point at which the curve between shear rate and viscosity reaches plateau was taken for plotting radiation dose versus shear rate for samples (a) CMG D.S. = 0.1 and (b) 0.2, (c) HEG M.S. = 0.1 and (d) 0.2, and (e) MG D.S. = 0.1 and (f) 0.2 with respect to radiation dose.
