W/D NO S/S
This standard establishes a system of classification for sealedradioactive sources based on performance specifications related toradiation safety. It does not consider the radiation output of thesealed source.
The standard provides a manufacturer of sealed radioactivesources with a set of tests to evaluate the safety of its productsunder specified conditions, and also to assist a user of suchsources to select types that suit an application, especially whereprotection against radioactive contamination is concerned. Thisstandard also provides guidance to regulatory authorities.
The tests fall into several groups, including, for example,exposure to abnormally high and low temperature and a variety ofmechanical tests. Each test can be applied in several degrees ofseverity.
Although the standard classifies sealed sources by a variety oftests, it does not imply that a sealed source will maintain itsintegrity if used continuously at the rated classification. Forexample, a sealed source tested for one hour at 600°C (1112°F) mayor may not maintain its integrity if used continuously at 600°C(1112°F).
Table 4 of this standard includes a list, which is not intendedto be comprehensive, of typical applications of sealed radioactivesources with a suggested performance classification for eachapplication. These classifications are minimum requirementscorresponding to the applications in the usual environment. Factorsto be considered for applications in especially severe environmentsare listed in Sections 4.2 and 4.3.
This standard makes no attempt to classify the design ofsources, their method of construction, or their calibration interms of the radiation emitted.
Several subjects relating to sealed sources and their testingare not treated in detail in this standard, including selectedbrachytherapy sources, self-luminous light sources and IAEA testsfor special-form radioactive material. These subjects are coveredby separate standards as listed in Section 4.4.
