Diapositive 1

❑

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

❑

=|Ave Deviation| + 1.96

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
