This standard establishes a system of classification for sealed
\nradioactive sources based on performance specifications related to
\nradiation safety. It does not consider the radiation output of the
\nsealed source.<\/p>\n
The standard provides a manufacturer of sealed radioactive
\nsources with a set of tests to evaluate the safety of its products
\nunder specified conditions, and also to assist a user of such
\nsources to select types that suit an application, especially where
\nprotection against radioactive contamination is concerned. This
\nstandard also provides guidance to regulatory authorities.<\/p>\n
The tests fall into several groups, including, for example,
\nexposure to abnormally high and low temperature and a variety of
\nmechanical tests. Each test can be applied in several degrees of
\nseverity.<\/p>\n
Although the standard classifies sealed sources by a variety of
\ntests, it does not imply that a sealed source will maintain its
\nintegrity if used continuously at the rated classification. For
\nexample, a sealed source tested for one hour at 600\u00b0C (1112\u00b0F) may
\nor may not maintain its integrity if used continuously at 600\u00b0C
\n(1112\u00b0F).<\/p>\n
Table 4 of this standard includes a list, which is not intended
\nto be comprehensive, of typical applications of sealed radioactive
\nsources with a suggested performance classification for each
\napplication. These classifications are minimum requirements
\ncorresponding to the applications in the usual environment. Factors
\nto be considered for applications in especially severe environments
\nare listed in Sections 4.2 and 4.3.<\/p>\n
This standard makes no attempt to classify the design of
\nsources, their method of construction, or their calibration in
\nterms of the radiation emitted.<\/p>\n
Several subjects relating to sealed sources and their testing
\nare not treated in detail in this standard, including selected
\nbrachytherapy sources, self-luminous light sources and IAEA tests
\nfor special-form radioactive material. These subjects are covered
\nby separate standards as listed in Section 4.4.<\/p>\n","protected":false},"excerpt":{"rendered":"
