26、tions and interventional procedures. NOTEPROTECTIVE DEVICES are not intended by themselves to provide complete protection of persons, but are used to reduce the dose to persons where other methods of protection against X-RADIATION are insufficient or not applicable. 1.2 Object This standard deals wi

27、th: general requirements on the ACCOMPANYING DOCUMENTS, and on design and materials used; standard sizes, particular design features, minimum ATTENUATION properties of materials, marking and standardized forms of statements of compliance with this standard. It covers PROTECTIVE CLOTHING mainly for t

28、he protection of the OPERATOR, such as: PROTECTIVE APRONS; PROTECTIVE GLOVES; PROTECTIVE MITTENS; and PROTECTIVE DEVICES for gonads for the protection of the PATIENT, such as: PROTECTIVE GONAD APRONS; SCROTUM SHIELDS; OVARY SHIELDS; SHADOW SHIELDS. The latter group of PROTECTIVE DEVICES is intended

29、to be used during RADIOLOGICAL examinations to minimize the effects of IRRADIATION on the reproductive organs particularly with regard to genetic damage. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this p

30、art of IEC61331. At the time of publication, the editions indicated were valid.

32、Degree of requirements In this standard, certain terms which are not printed in SMALL CAPITALS have particular meanings, as follows: 3.2 Use of terms In this standard, terms printed in SMALL CAPITALS are used in accordance with their definitions in IEC60788, in this standard or in other IECpublicati

33、ons referenced in Annex A. NOTEAttention is drawn to the fact that, in the case that the concept addressed is not strongly confined to the definition given in one of the publications listed above, the corresponding term is printed in lower case letters. An index of defined terms used in this standar

34、d is given in Annex A. 3.3 Defined terms For the purpose of this part of IEC61331 the following additional definitions apply. 3.3.1 PROTECTIVE GONAD APRON PROTECTIVE APRON worn by the PATIENT to protect the region of the gonads as an alternative to the use of a SCROTUM SHIELD or an OVARY SHIELD; see

35、rm-64-05 of IEC60788 3.3.2 SHADOW SHIELD PROTECTIVE DEVICE to intercept the RADIATION BEAM in the areas of the gonads, to be used when a SCROTUM SHIELD and an OVARY SHIELD cannot be used “shall” indicates a requirement that is mandatory for compliance; “should” indicates a strong recommendation that

36、 is not mandatory for compliance; “may” indicates a permitted manner of complying with a requirement or of avoiding the need to comply; “specified” is used to indicate definitive information stated by the MANUFACTURER in ACCOMPANYING DOCUMENTS or in other documentation relating to the equipment unde

38、sential 4 General 4.1 ACCOMPANYING DOCUMENTS PROTECTIVE DEVICES shall not be provided without ACCOMPANYING DOCUMENTS. The ACCOMPANYING DOCUMENTS shall contain information on the following: a) identity of the items of PROTECTIVE DEVICE(S) to which they apply, by reference to type or to individual ite

39、ms, as appropriate; b) description of all markings on the items, with explanation of their meanings; c) INSTRUCTIONS FOR USE, which shall contain: d) recommendations for storage when not in use; e) recommendations for methods and materials to be used for cleaning and disinfection; f) recommended met

40、hod and frequency of periodic inspection by the USER in order to verify the maintenance of ATTENUATION properties; g) particulars of compliance with this standard. Any information included in the ACCOMPANYING DOCUMENTS that is particularly intended to be read by the PATIENT, shall be repeated in a s

41、eparate part containing all such information. 4.2 Language of the ACCOMPANYING DOCUMENTS This standard contains no requirements concerning the language(s) in which the ACCOMPANYING DOCUMENTS provided are to be written. Attention is drawn to the fact that when the ACCOMPANYING DOCUMENTS are written i

42、n a language other than that in which they were originally drafted and approved by the MANUFACTURER of the PROTECTIVE DEVICES, these documents shall be checked carefully by an expert who, wherever possible, should be authorized by the MANUFACTURER to act in that capacity. The ACCOMPANYING DOCUMENTS

43、shall state the language(s) in which they were originally drafted, approved or supplied by the MANUFACTURER and shall give a reference identifying at least one original version. 4.3 General requirement on marking PROTECTIVE DEVICES shall be marked so that their correlation to the pertaining ACCOMPAN

44、YING DOCUMENTS is ensured. 4.4 Design 4.4.1 PROTECTIVE DEVICES for the protection of OPERATORS should be so designed that they can be put on and taken off without assistance. 4.4.2 PROTECTIVE DEVICES for the protection of the PATIENT shall be designed so that they can be easily applied, and they sho

45、uld be designed so that they can be properly placed and, where necessary, fixed by the PATIENTS themselves. 4.5 Materials 4.5.1 The materials effecting the ATTENUATION shall be homogeneously distributed and shall contain elements of high atomic number. 4.5.2 The ATTENUATION properties shall not vary

46、 under conditions of NORMAL USE. 4.5.3 All outer and inner accessible surfaces of PROTECTIVE DEVICES shall be suitable for cleaning and disinfection. 4.5.4 It shall not be possible to touch uncovered or uncoated surfaces of metallic lead or lead compounds. 5 PROTECTIVE APRONS NOTEPROTECTIVE APRONS a

47、re intended to be worn by persons who are present in the EXAMINATION ROOM during RADIOLOGICAL examinations with or without interventional procedures. They are intended primarily to protect the main part of the body of the OPERATOR. To protect the complete body, additional protective devices have to

48、be used, for example thyroid shields, protective eye glasses or helmets. For the purpose of this standard, four different categories of PROTECTIVE APRONS are defined: light PROTECTIVE APRONS; heavy PROTECTIVE APRONS; light closed PROTECTIVE APRONS; heavy closed PROTECTIVE APRONS. NOTELight PROTECTIV

49、E APRONS may be worn for example in the operating theatre and in the gypsum room, or if the SIGNIFICANT ZONE OF OCCUPANCY is protected against STRAY RADIATION by other PROTECTIVE DEVICES, for example fixed on the X-RAY EQUIPMENT. 5.1 Design PROTECTIVE APRONS shall consist of one or more layers of protective material and shall be designed to cover the front part of the body from the throat down to at least the knees, the entire breastbone and the shoulders. The width of the protective material on each shoulder sh
