Autor: S M Judge, R M Coulon, M G Cox, L Karam, P Knoll, C Michotte, Z Msimang, B E Zimmerman

Publikováno v: Metrologia. 60:012001

The medical use of radionuclides depends on the accurate measurement of activity (Bq) for regulatory compliance, patient safety, and effective treatment or image quality. In turn, these measurements rely on the realization of primary standards of act
