Dose Course 2018_Flipping book

Outline of part 2

❑ Now we have the means to characterise uncertainty – how does that

apply in comparing calculated and measured doses?

❑ Fact : There is a True dose at every point in an irradiated object.

❑ We estimate this dose with measurement or models

❑ Can assign a tolerance to individual points or to a set of points

❑ D =|Ave Deviation| + 1.96 s Confidence Limit (Venselaar) (CI=95%, P=0.05)

❑

See TK lecture for details

❑ Need to set Tolerance and Action limits and its relation to the

uncertainty of measurements
