Action limits - Proposed philosophy
Step 1: Determine the uncertainty ( ) for the dose measurement, yielding the probability distribution for the true dose .
Dm - C
/2
Dm + C
/2
Dose (Gy)
C
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 .
