Measurement of radioactivity. Alpha-, beta- and photon emitting radionuclides. Reference measurement standard specifications for the calibration of surface contamination monitorsWhat is ISO 8769 about? ISO 8769 discusses the measurement of radioactivity. ISO 8769 specifies preferred reference radiations for the calibration of surface contamination monitors. These reference radiations are realized in the form of adequately characterized large area sources specified, without exception, in terms of surface emission rate and activity which are traceable to national standards. For the calibration of surface contamination monitors,
