Foreword
This standard replaces GB/T 11682-1989 "Low background α meter."
This standard and GB/T 11682-1989, compared amended as follows.
--- Standard name was changed to "low background α and/or β measuring instrument";
--- Increase in the content of measuring low background β;
--- "Normative references" added the standard reference;
--- "Terms and Definitions" added "cross-ratio" of the content;
--- Increase mutual interference index α and β, that is, cross track than the target;
--- Increased requirements and test methods for electromagnetic compatibility of the instrument;
--- Increased the instrument software General requirements;
--- Remove the "Table 1 instrument rating" Technical indicators background stability;
--- Remove the "Table 2 changes affect the amount of projects and requirements" technical requirements change limits and the background count rate.
Appendix A of this standard is a normative appendix.

Low background α and/or β measuring instrument
1 Scope
This standard specifies the technical requirements, test methods and inspection rules for low background α and/or β measuring instrument.
This standard applies to the measurement of weak α, β radioactivity or instrument surface emissivity, but also for multi-purpose instrument for measuring weak α or β
Radioactive portion.
This standard does not apply to measuring α or β spectrum types of instruments.
2 Normative references

3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Due to the non-measured physical quantity signal.
3.2
Instrument under normal operating conditions, the sample tray without sources, the instrument indicated value.
3.3
No external radioactive but by the same sample of material, according to the normal procedure of making planar samples tested.
3.4
Instrument under normal operating conditions, the measured value indicating a blank sample.
3.5
Without the presence of the test sample, measuring the inherent count means. These counts from cosmic rays, radioactivity in the environment
Substances and radioactive contamination of the detector itself.
3.6
The background count per unit time.
