Figure 8.

Temporal stability—3D evaluation. The parameters of the linear regression model (see Sec. 2E2), C (initial distribution) and m (creep rate) are shown for three slices (similar to Fig. 4) in the top two rows. The third row shows the R² value of the linear fit for the three slices. The percent creep was uniform in the irradiated regions of the dosimeter and was estimated from the model to be 0.54%∕h (fourth row). In the third and fourth row, the dotted regions were excluded from analysis because of uncertainty in measurement of low dose (<6% dose).
