Foreword
This part of GB/T 7165 "gaseous effluents (radioactive) activity continuous monitoring equipment" Part 4. The total includes a lower standard
Column five parts.

GB/T 7165.5 "gaseous effluents (radioactive) activity continuous monitoring equipment - Part 5. Particular requirements for tritium monitors."
This section is amended to GB/T 7165.4-1989's.
This section identical with IEC 60761-4.2002 "gaseous effluents (radioactive) activity continuous monitoring equipment - Part 4. radioactive iodine
Particular requirements for monitors "(in English).
For ease of use, this section made the following editorial changes.
--- Delete the original International Standards and Introduction;
--- With a decimal point instead of the original international standard decimal point ",". ",";
--- Will be in "2 Normative references" existing national standards and industry standards relevant international standards to our standards (in
GB/T 2423.5 instead of IEC 60028-2-27. 1987, with GB/T 7165.1-2005 instead of IEC 60761-2.2002, in order to
GB/T 17626 instead of IEC 61000, GB 9254-1998 to replace the IEC /CISPR22.1997);
--- Retain only the contents of the current used in the voltage and frequency of the AC power supply.
This Part replaces GB/T 7165.4-1989 "gaseous effluents (radioactive) activity continuously monitoring Part IV. iodine monitors
Particular requirements. "
Section compared with the GB/T 7165.4-1989 The main changes are as follows.
--- Iodine monitor type, and an increase in the chimney pipe direct measurement of iodine monitors;
--- Sampling and detection devices, increasing the demands on the pump;
--- Select the type of reference source added to the reference gas source, the source added for special provisions;
--- Standard test conditions were amended to increase the flow, electrostatic field, radon progeny and chemical pollution standard test conditions, modify the set
--- Linearity requirements inherent relative error, revised from 20% to 10%;
--- Indication of the duration of the stability test requirements, as amended by the 500h 100h;
--- Alarm threshold stability test time required by the revised 500h 100h, drift alarm threshold requirement from 20% to 5%;
--- Meter indoor ambient temperature requirements by the 10 ℃ ~ 50 ℃ revised to 10 ℃ ~ 35 ℃;
--- Relative humidity test temperature from 30 ℃ revised to 35 ℃;
--- Change the test contents affect the amount of increase for seals, mechanical shock and electromagnetic compatibility requirements;
--- Air circuit test content increases the collection efficiency of the test, the amount of time on the value range by a revised 1h ~ 100h 30min ~
100h;
--- "Air dose rates" to "air kerma rate."
Use this section should be combined with the GB/T 7165.1-2005.

GB/T 7165.4-2008/IEC 60761-4.2002
Gaseous effluents (radioactive) activity Continuous monitoring equipment
Specific requirements for radioactive iodine monitors. Part 4
1 Scope
GB/T 7165 This section applies to all forms of radioactive iodine for the same time, delay or sequentially measuring device. When the flow of discharge
When sampling measurements, attached to the aerosol iodine generally consists of pre-filter is collected, and then analyzed separately in the laboratory, to mention
For complete measurement.
Radioactive iodine monitors should have the following features.
--- Measuring gaseous exhaust stream total activity volume activity of iodine and iodine compounds and emissions of radioactive iodine;
--- When the radioactivity concentration or total activity iodine or an iodine compound exceeds a preset threshold, the start alarm signal.
Such devices will be measured in the presence of gaseous effluents of radionuclides other activity, including natural radionuclides. Its
He radionuclide screening when measuring low levels of radioactive iodine is very important.
The chimney or ventilation pipe, this section takes into account both the use of activated carbon as iodine sampling medium, but also consider the direct iodine
measuring.
The purpose of this section is to set out the provisions of Chapter 4 iodine monitors specific standard requirements, including technical characteristics and general test conditions, and give
Examples of possible approaches.
GB/T 7165.1-2005 in the general requirements for such equipment, technical characteristics, test methods, radiation characteristics, electrical characteristics, mechanical
Mechanical characteristics, security features and environmental characteristics. Unless otherwise noted, these requirements apply to this section.

3 Terms and Definitions
GB/T 7165.1-2005 to establish the following terms and definitions apply to this section.
3.1
Unless otherwise indicated, the portion used "iodine" refers to compounds and non-radioactive iodine compounds exist in all forms, including
Attached iodine in aerosol.
Note. iodine is usually the first aerosol collected on a pre-filter, and then analyzed separately in the laboratory.
