Introduction

Example: A dose is measured and found to be 1 Gy. However, even assuming an identical uncertainty of measurement, this result might be reported either as:

(1 ± 0.01) Gy

with 99% confidence limits

or:

(1 ± 0.007) Gy

with 95% confidence limits

Same measurement, same accuracy, different reporting
