Action limits - Proposed philosophy

Step 1:

Determine the uncertainty (s) for the dose measurement, yielding the probability distribution for the true dose .

Dm - C

/2

Dm + C

/2

a

a

Dose (Gy)

C

a Dose measurement = Dm

Error probability = (1-CL)/2 (i.e. 2.5% when CL=95%)

Step 2:

Set a confidence level CL for the true dose, e.g. CL =95%, and determine the corresponding dose interval C a .
