a
All gel formulations are standard (6%T, 50%C—where applicable) except for parameters in parentheses.
b
Dose resolution (absolute, Gy), 95% confidence (Hill et al 2005a, Trapp et al 2001a).
c
Relative (%) dose resolution, 95% confidence, calculated using uncertainty in NCT = 0.3 H for all gels. Actual dose resolution may vary depending on the image noise in a particular situation.
