Method trueness and measurement uncertainty resulted comparable, while the precision of ion chromatography approach was higher.

Determination of a cut-off was done by using Bhattacharya statistics and by adding a measurement uncertainty interval.

Discussion: Operator subjectivity can be quantified to include within measurement uncertainty budgets, required for various standards and qualifications.

Measured values were intercompared with published sets of computed kQ values and agreement was found to be within measurement uncertainty (1%, one standard deviation).

The range measurement uncertainty for doses less than 1 cGy was found to be ±0.355mm, indicating high precision for low dose detection.

There was no measurable dose dependence for k bq within the 500-7002 mGy range outside of the expanded measurement uncertainty of 3.65% (k = 2).
