The issuance of a Cofrac calibration certificate guarantees the traceability of the results to the International System of Units (SI) as well as the documentary traceability describing the methods and the evaluation of the associated measurement uncertainties.
The Cofrac Calibration accreditation of the LNHB covers measurements of:
– activity, mass activity and emission flows (range 2-01),
– absorbed dose, equivalent dose and kerma (range 2-52).
Scope, fields, uncertainties and validity dates of LNHB accreditations are available on the Cofrac website.
