Traceability limit
 scroll 
Fixed characteristic value based on statistical processes
to evaluate the detection possibility for nuclear radiation measurements.
The numerical value of the traceability limit indicates the smallest
amount which can be detected with the measuring procedure concerned
at a given error probability. This is the basis for the decision whether
a measuring method meets certain requirements and is therefore suited
for the given measuring purpose. See 'detection
limit'. Examples for traceability limits to be achieved from the
guideline for the environmental monitoring of nuclear power plants:
Gamma local dose: |
0.1 mSv/year, |
Aerosols*: |
0.4 mBq/m3, |
Precipitation*: |
0.05 Bq/l, |
Vegetation*: |
0.5 Bq/kg, |
Vegetable food*: |
0.2 Bq/kg, |
Vegetable food, Sr-90: |
0.04 Bq/kg, |
Milk, I-131: |
0.01 Bq/l. |
