Introduction

JJF1002-2010 "national verification procedures write rules", JJF1001-2011 "common terminology and measurement Definitions ", JJF1059.1-2012" Evaluation and Expression of Uncertainty in Measurement "together constitute the support of the formulation of regulations The basic series of specifications. The regulations reference the International Electrotechnical Commission (IEC ) standard IEC 62089.2001 "Nuclear Instruments -α/β gas proportional Counter calibration and use "(Nuclearinstrumentation-Calibrationandusageofalpha/betagas proportionalcounters), combined with the practical application of domestic instrument making, it has the following characteristics. --- Requirements for 210Po source verification instruments α detection efficiency ratio and cross track (see 7.1.1.1). --- Β detection efficiency requirements for low-energy source 14C test instrument (see 7.1.1.2). --- Emphasize the background, and the efficiency and reproducibility of test for measuring the counting statistics of the requirements (see 7.3.1, 7.3.2,7.3.3). This procedure was first formulated. Gas flow proportional counter total α, total β meter verification procedures

1 Scope

The order applies to the total gas flow proportional counter α, β meter total initial verification, verification and subsequent use an examination. Low background α, β measuring instrument and a liquid scintillation counter this regulation does not apply to the type of solid scintillation or semiconductor detectors Number of the test. 2.
