Introduction

The main basis for this specification in accordance with JJF 1071-2010 "National Calibration Specifications writing rules" written preparation Of GB/T 10259-2013 "liquid scintillation counter," and refer to the International Electrotechnical Commission standard IEC 61304.1994 "Nuclear Instrument Performance Verification liquid scintillation counter" (Nuclearinstrumentation- Liquid-scintilationcountingsystems-Performanceverification) and the American National Standards AN- SIN42.15.1990 "liquid scintillation counting system performance test" (Performanceverificationofliquid- 1986 sealed radioactive "for liquid scintillation counter. scintilationcountingsystem), ANSIN42.16 Check supply specifications "(SpecificationsforSealedRadioactiveCheckSourcesUsedinLiquid- ScintilationCounters). As radionuclide activity measurement instruments used in a liquid scintillation counter more β-ray emitting nuclide, in particular Low energy β-ray measurements of radionuclide 3H and 14C activity in. This specification defines a liquid scintillation counter calibrated measuring 3H and 14C Radionuclide detection efficiency calibration method is also applicable to other radionuclide detection efficiency calibration. The specification for the first time to develop. Liquid scintillation counter calibrated specifications
