27、 29661:2012+A1:2015 (E)3030BS EN ISO 29661:2017ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each mem

28、ber body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International El

29、ectrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopt

30、ed by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

31、 rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 29661 was prepared by Technical Committee ISO/TC 85, Nuclear energy, nuclear technologies, and radiological protection, Subcommittee SC 2, Radiological protection.iv ISO 2012 All rights reservedBS ISO 29661:

32、2012+A1:2015 ISO 29661:2012+A1:2015 (E) BS EN ISO 29661:2017IntroductionInternational Standards ISO 4037, ISO 6980, ISO 8529 and ISO 127891.12, with focus on photon, beta and neutron reference radiation fields, are each divided into several parts: one part gives the methods of production and charact

33、erization of reference radiation fields, and others describe the dosimetry of the reference radiation qualities and the procedures for calibrating and determining the response of dosemeters and doserate meters in terms of the operational quantities of the International Commission on Radiation Units

34、and Measurements (ICRU)25 26 27 28 31.The subject of these four International Standards is the same; they differ only in the kind of radiation each addresses. Their terms and definitions, and most of the descriptions of methods and procedures given are basically the same whatever the radiation. Neve

35、rtheless, they do differ, more or less, from one to the other in detail. This International Standard brings together terms and definitions and fundamental concepts common to all of them. Thus, it serves to harmonize International Standards on radiation protection.Besides definitions relating to cali

36、bration primary quantities, the operational quantities for area and individual monitoring are specified. For area monitoring, the operational quantities are ambient dose equivalent, H*(10), directional dose equivalents, H(0,07, ) and H(3,), and the appropriate dose rates. For individual monitoring u

37、sing personal dosemeters, the dose equivalent quantities, Hp(10), Hp(0,07) and Hp(3), and the respective dose rates are available. The method used to represent these operational quantities is the following. First, a basic (primary) quantity, such as air kerma free-in-air, fluence or absorbed dose to

38、 soft tissue, is measured. Then the appropriate operational quantity is derived by the application of the conversion coefficient that relates the basic (primary) quantity to the selected operational quantity. The procedure for the calibration and the determination of the response of radiation protec

39、tion dosemeters is described in general terms. Depending on the type of dosemeter under test, the position of the reference point is specified differently and the irradiation is either carried out on a phantom (for personal dosemeters) or free in air (for area dosemeters or area survey meters).With

40、the publication of this International Standard, it is intended that ISO 4037, ISO 6980, ISO 8529 and ISO 12789 be revised successively for further harmonization since, among other aspects, certain of their definitions differ from those published here and the symbols chosen for this International Sta

41、ndard are more consistent with ICRU reports and other International Standards used for radiation protection purposes.

42、oncepts1 ScopeThis International Standard defines terms and fundamental concepts for the calibration of dosemeters and equipment used for the radiation protection dosimetry of external radiation in particular, for beta, neutron and photon radiation. It defines the measurement quantities for radiatio

43、n protection dosemeters and doserate meters and gives recommendations for establishing these quantities. For individual monitoring, it covers whole body and extremity dosemeters (including those for the skin and the eye lens), and for area monitoring, portable and installed dosemeters. Guidelines ar

44、e given for the calibration of dosemeters and doserate meters used for individual and area monitoring in reference radiation fields. Recommendations are made for the position of the reference point and the phantom to be used for personal dosemeters. This International Standard also deals with the de

45、termination of the response as a function of radiation quality and angle of radiation incidence.It is intended to be used by calibration laboratories and manufacturers.2 Normative referencesThe following referenced documents are indispensable for the application of this document.
