21、 a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to
22、other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in t
23、he subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditi
24、ons determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC Nation
25、al Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way
26、in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC P
27、ublication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC
28、 is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its
29、technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other
30、 IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the s
31、ubject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard 61017 has been prepared by subcommittee 45B: Radiation protection instrumentation, of IEC technical committee 45: Nuclear instrumentation. This first edition of IEC 61017
32、cancels and replaces the first edition of IEC 61017-1, published in 1991, and the first edition of IEC 61017-2, published in 1994. It constitutes a technical revision. The main technical changes with the previous editions are as follows: this standard explicitly describes air absorbed dose and dose
33、rate, ambient dose equivalent dose and dose rate, in addition to air kerma and kerma rate; this standard includes the description of the typical detector types for use in environmental monitoring. BS IEC 61017:2016 6 IEC 61017:2016 IEC 2016 The text of this standard is based on the following documen
34、ts: FDIS Report on voting 45B/825/FDIS 45B/837/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that t
35、he contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. BS IEC 6
36、1017:2016IEC 61017:2016 IEC 2016 7 INTRODUCTION Exposure of members of the public to ionizing radiation produced by nuclear and other facilities is subject to control. An essential part of control is the measurement of the environmental radiation levels in the neighborhood of these facilities . The
37、evaluation of the environmental radiation dose from photons is difficult. The composition of the background radiation is complex and includes contributions from natural sources such as cosmic radiation and terrestrial radioactivity in addition to man-made radioactivity arising from the operation of
38、nuclear facilities and fall-out from nuclear weapon tests. This, if further complicated by the variation in the natural background radiation dose, varies in time due to variation in ambient radon concentrations and space due to spatial heterogeneity of the natural environmental background. The requi
39、rements specified in this standard relate to normal operations of the assembly. Should an assembly be required for emergency conditions on-site at nuclear facilities then the requirements of IEC 60846-2 should also be applied to the assembly, particularly with regard to overload characteristics. The
40、 requirements for portable work place monitors to measure ambient and/or directional dose equivalent (rate) are specified in IEC 60846-1. BS IEC 61017:2016 8 IEC 61017:2016 IEC 2016 RADIATION PROTECTION INSTRUMENTATION TRANSPORTABLE, MOBILE OR INSTALLED EQUIPMENT TO MEASURE PHOTON RADIATION FOR ENVI
41、RONMENTAL MONITORING 1 Scope This International Standard is applicable to transportable, mobile or installed assemblies intended to measure environmental air kerma rates or air absorbed dose rates from 30 nGyh1to 30 Gyh1or ambient dose equivalent rates from 30 nSvh1to 30 Svh1, or air kerma or air ab
42、sorbed dose from 10 nGy to 10 mGy, or ambient dose equivalent from 10 nSv to 10 mSv, due to photon radiation of energy between 50 keV and 7 MeV. The measurable range of dose and dose rate can be extended by agreement between the purchaser and the manufacturer. This extension may be realized by combi
43、ning more than one detector, for example NaI(Tl) scintillator and ionization chamber. For most environmental applications, instruments may measure over a more limited energy range of 80 keV to 3 MeV. NOTE 1 80 keV to 3 MeV has been chosen to cover the energies of the chief environmental and man-made
44、 radio-nuclides that contribute to the environmental dose. The term “dose” used in this standard means the quantity, air kerma, air absorbed dose, and ambient dose equivalent, that the instrument is intended to measure. If the assembly is to be used to measure these quantities in the area surroundin
45、g a nuclear reactor producing 6 MeV radiation from the 16N isotope, it will be necessary to determine the response at this energy. An absorbed dose in air, which uses the same unit, Gy, as air kerma can be taken to have the same numerical value as air kerma under the condition of electron equilibriu
46、m. Passive devices such as Thermo-Luminescence Dosemeter (TLD), Optically Stimulated Luminescence (OSL) Dosemeter or Glass Radio-Photo Luminescence (RPL) Dosemeter are not covered by this standard. Installed assemblies should be capable of operating continuously. This standard does not provide for t
47、he measurement of beta and neutron radiation. The equipment covered by this standard comprises a detector assembly and processing circuits, which may be connected together either rigidly or by means of a flexible cable, or incorporated into a single assembly. The equipment assembly may also include
48、circuits for displaying readings, alarms and communication. This equipment should meet the environmental conditions of use. Examples of instruments include (detailed information is described in Annex A): a) Ionization chamber This is suitable for the measurement of air kerma and air absorbed dose an
49、d dose rate. In the environment, the correction due to temperature and atmospheric pressure may be required. NOTE 2 For the measurement of ambient dose equivalent and dose equivalent rate the energy response may be compensated. b) Geiger-Muller (GM) counter The energy response should be corrected. GM counters may overestimate the readings due to the dose (rate) from cosmic radiation. c) Scintillation detector BS IEC 61017:2016IEC 61017:2016 IEC 2016 9 The energy respons
