Introduction

This specification is based on JJF 1071-2010 "National Metrological Calibration Rules". Radioactivity (specific) activity rapid detector using a total amount of γ radioactivity measurement methods, mainly used in drinking Water, beverages and cereals, meat, vegetables and cosmetics and other radioactive (specific) live fast detection. This specification Preparation of reference JJG417-2006 "γ spectrometer", JJG377-1998 "radioactive activity meter", and Japan with the bit Sui Association in February.2012 promulgated the "radioactive cesium screening of food" guidance law and other technical information. This specification is the first release. Standard for Calibration of Radioactivity (Ratio) Activity Fast Detector

1 Scope

This specification applies to gamma radioactivity measurement range (40 ~ 104) Bq, for all-spectrum or a single specific nuclide γ Radioactivity measurement of radioactivity (specific) activity Fast detector calibration, specific nuclides mainly include 137Cs, 131I and so on.
