Measured amount of an element with stated measurement uncertainty that is simultaneously irradiated with the sample during activation analysis.
Notes: - The term 'calibrator' is preferred over 'comparator'.
- If one calibrator is used (single calibrator method, which is preferred over 'single comparator method'), it is essentially identical to a flux monitor (except that the latter is not necessarily linked to activation analysis).
