The National Dissemination of International Measurements

Abstract

The paper presents the most significant actions which a primary Radionuclide Metrology Laboratory must accomplish, in order to disseminate the international equivalence to the entire national traceability chain: absolute standardization methods and demonstration of international equivalence, construction and calibration of a consistent set of secondary standardization equipment, preparation of radioactive standards. Delivery of radioactive standards to the end users and carrying out metrological services. Organization of national proficiency tests with the users. International validation of secondary standards by proficiency tests and establishment of a Quality System Assurance.

Role of the Radionuclide Metrology in Nuclear Medicine

“…IFIN-HH, RML organized in the past several national comparisons mainly for a scientific output, in order to understand which explanations for noncorresponding results are. The comparisons regarded the measurement of 131 I (Sahagia et al1996b) and the set 99m Tc and 57 Co, (Sahagia & Woods. 2008c).…”
