5、vertissement pour rayonnements ionisants Symbole supplmentaire BS ISO 21482:2007ii iiiForeword ISO (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 th
6、rough ISO technical committees. Each member 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 collab
7、orates closely with the International Electrotechnical 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 Stan
8、dards. Draft International Standards adopted 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
9、 this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 21482 was prepared by Technical Committee ISO/TC 85, Nuclear energy, Subcommittee SC 2, Radiation protection. BS ISO 21482:2007iv Introduction The basic ionizing-r
10、adiation symbol, “the trefoil” ISO 361, ISO 7010:2003, Table 1 (Reference number W003), is used internationally to indicate the presence of radiation. There is a history of people, in particular those persons with insufficient technical education or background, receiving serious injuries or fataliti
11、es from handling large sealed radioactive sources and not correctly understanding the meaning of the basic ionizing radiation symbol on the source. The ability to interpret and understand the symbol is of crucial importance for all people. With these problems in mind, the competent UN authority, the
12、 International Atomic Energy Agency (IAEA) with direction from the international community saw a necessity to develop a new symbol that is capable of fulfilling all the requirements placed on a warning symbol. For that purpose, the IAEA designed a number of symbols with different colours and shapes
13、and evaluated them in a number of preliminary tests. A series of assessments and comparisons were completed among people with insufficient technical education or background, children and among different cultures in 11 different countries. The result is put forth in this International Standard. This
14、symbol is intended to supplement the basic ionizing radiation symbol. BS ISO 21482:20071Ionizing-radiation warning Supplementary symbol 1 Scope This International Standard specifies the symbol to warn of the presence of a dangerous level of ionizing radiation from a high-level sealed radioactive sou
15、rce that can cause death or serious injury if handled carelessly. This symbol is not intended to replace the basic ionizing radiation symbol ISO 361, ISO 7010:2003, Table 1 (Reference number W003), but to supplement it by providing further information on the danger associated with the source and the
16、 necessity for untrained or uninformed members of the public to stay away from it. This symbol is recommended for use with International Atomic Energy Agency (IAEA) Category 1, 2, and 3 sealed radioactive sources. These sources are defined by the IAEA as having the ability to cause death or serious
17、injuries. 2 Shape, proportions and colour of the symbol The supplementary ionizing radiation warning symbol (see Figures 1 and A.1) is diagrammed below. The symbol shall have a red (pantone red No. 187) background with black figures and a white outline of the figures. The symbol is acceptable withou
18、t colour if the use of colour is not feasible, such as in the case of engraving the symbol on the source. The symbol should not be made smaller than 3,0 cm to assure that it is clearly visible. Figure 1 Supplementary ionizing radiation warning symbol See Figures A.2 to A.6 for the individual element
19、s of which this symbol is composed. BS ISO 21482:20072 3 Application of the symbol The supplementary radiation warning symbol should be placed in close proximity to the source preferably on the shield or near the point of potential access to the source. The intent in the symbol on the shield is to c
20、onvey the message that dismantling the device is very dangerous. Due to the small size of most sources, placing the symbol directly on the source might not be feasible. Placing the symbol on the device shielding so it can be seen prior to accessing the actual source is desirable. The symbol may be e
21、ngraved, placed on a label and mounted on the housing or attached as a tab. The symbol shall be closely associated with the device housing the source, as a warning not to dismantle the device or get any closer to the source. When practical, the symbol should be located directly on the source shield
22、and under the device covers, such that it is not visible during normal use but would be visible if anyone attempts to dismantle the device. If there is no device cover, the symbol should be located on the outside housing in a discrete location, clearly visible prior to disassembly, but not visible d
23、uring normal use (e.g., locating the symbol close to the source access point). The symbol shall not be located on the external surfaces of transport packages, freight containers, conveyances or on building access doors.
