Measurement of radioactivity. Alpha-, beta- and photon emitting radionuclides. Reference measurement standard specifications for the calibration of surface contamination monitors Ingestion-build-100580 in liquid or vapour phase1 Scope This document specifies the characteristics of reference measurement standards of radioactive surface contamination, traceable to national measurement standards, for the calibration of surface contamination monitors. This document relates to alpha emitters, beta emitters, and photon emitters of maximum photon energy not greater than 1,5 MeV. It does not describe the procedures involved in the use of these reference measurement standards for
