Foreword

The standard reference IAEA IAEA-TECDOC-602-1991 "quality control of nuclear medicine equipment." This standard replaces GB/T 15476-1995 "renal instrument." This standard and GB/T 15476-1995 phase compare the main differences are as follows. a) an increase of scintillation detectors, shield, working distance, point source response curve, sensitivity point source, shielding leakage of terms and definitions (See Chapter 3); b) increasing the relevant technical content (see Chapter 4); c) an increase in Appendix B "point source and its structural dimensions." The Standard Appendix A and Appendix B is a normative appendix. The standard proposed by China National Nuclear Corporation. This standard by the National Nuclear Instrument Standardization Technical Committee (SAC/TC30) centralized. This standard was drafted. Xi'an Nuclear Instrument Factory. The main drafters of this standard. Sun Liping, Liangping. This standard replaces the standards previously issued as follows. --- GB/T 15476-1995. Renal instrument

3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 It refers to a region of the probe detection. In the region, when the point-like radiation source is moved in the same distance from the center of the crystal with a series of arcs When its count rate of not less than 90% corresponding to the central axis of the crystal count rate. 3.2 In the vertical direction of the axis of the probe, point-like sources count rate of not less than 90% of the central counting rate maximum distance. 3.3 Limit detector field of view, to exclude adjacent tissue or other radioactive interference by lead or tungsten alloy material composed of a ray attenuation Single-hole or perforated member. 3.4 Setting the pulse amplitude analyzer upper and lower thresholds. Pulses generated radioactive sources in the upper and lower threshold window falls into that part of the pulse Count rate. Note. Formerly known as differential count rate. 3.5 Instrument in the absence of sources of interference measured count rate, referred to as the bottom.
