19、ny IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Sta
20、ndardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee
21、has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sens
22、e. 4) In order to promote international unification, IEC National Committees undertake t o apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional stand
23、ard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this Inte
24、rnational Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60846 has been prepared by subcommittee 45B: Radiation pro- tection instrumentation, of IEC technical committee 45: Nuclear instrume
25、ntation. This third edition cancels and replaces the second edition issued in 2002, constitutes a tech- nical revision and includes and replaces 61017-1 and 61017-2. The text of this standard is based on the following documents: WD1 Report on voting of 2006-02-09 Full information on the voting for t

Annex A forms an integral part of this standard. The committee has decided that the contents of this publication will r

28、ADIATION PROTECTION INSTRUMENTATION AMBIENT AND/OR DIRECTIONAL DOSE EQUIVALENT (RATE) METERS AND/OR MONITORS FOR BETA, X AND GAMMA RADIATION Part 1: Portable workplace and environmental meters and monitors 1 Scope and object This International Standard applies to dose equivalent (rate) meters and/or
29、 monitors for the measurement of ambient dose equivalent (rate) and/or directional dose equivalent (rate) from external beta, X and gamma radiation, as recommended in ICRU Report 47. NOTE 1 If both quantities, ambient dose equivalent and directional dose equivalent are meant, the term dose equivalen
30、t may be used as an abbreviation. This first part of IEC 60846 applies only to portable meters and monitors which are intended to be used in both the workplace and the environment. It applies to devices that measure the dose equivalent or dose equivalent rate from external beta and/or X and gamma ra
31、diation in the dose range between 0, 1 Sv and 10 Sv and the dose rate range between 0,1 Sv h-1 and 10 Sv h-1 and in the energy ranges given in the following Table. All the energy values are mean energies with respect to the prevailing dose quantity. Measuring quantity Energy range for Photon radiati
32、on Energy range for Beta-particle radiation H*(10) 12 keV to 10 MeV H(0,07) 8 keV to 250 keV 0,07 MeV1) to 1,2 MeV almost equivalent to Emax from 225 keV to 3,54 MeV 1) For beta-particle radiation, an energy of 0,07 MeV is required to penetrate the dead layer of skin of 0,07 mm (almost equivalent to
33、 0,07 mm of ICRU tissue) nominal depth. NOTE 2 Where a dose rate meter or monitor may be attached to a supplementary probe used to monitor contamination, the relevant standard for that probe is IEC 60325. If national legislation requires the use of different measuring quantities. For example air ker
34、ma or exposure, the standard may be used with the respective adjustments. In this document, the expression “dose equivalent (rate)“ is used when the provisions apply to both the measurement of dose equivalent and the measurement of dose equivalent rate. NOTE 3 It does not apply to medical radiology
35、which is within the scope of technical committee 62, where the conditions of radiation exposure may be extremely inhomogeneous, but precisely known. NOTE 4 It does not apply to instruments intended to be worn by an individual for the purpose of estimating the radiation dose received by that individu
36、al. The object of this standard is to specify the design requirements and the performance characteristics of dose equivalent (rate) meters intended for the determination of ambient dose equivalent (rate) and directional dose equivalent (rate) as defined in ICRU Report 47. Accordingly, this standard
37、specifies: a) general characteristics, the functions and performance characteristics of dose equivalent (rate) meters; b) the methods of test to be used to determine compliance with the requirements of this standard. Some countries may wish to use this type of dose equivalent (rate) meter for measur
38、ements in the framework of legal metrology.
