Radiation protection - Sealed sources - Leakage test methods

This document specifies the different leakage test methods for sealed sources. It gives a comprehensive set of procedures using radioactive and non-radioactive means. This document applies to the following situations: — leakage testing of test sources following design classification testing in accordance with ISO 2919[1]; — production quality control testing of sealed sources; — periodic inspections of the sealed sources performed at regular intervals, during the working life. Annex A of this document gives guidance to the user in the choice of the most suitable method(s) according to situation and source type. It is recognized that there can be circumstances where special tests, not described in this document, are required. It is emphasized, however, that insofar as production, use, storage and transport of sealed radioactive sources are concerned, compliance with this document is no substitute for complying with the requirements of the relevant IAEA regulations[17] and other relevant national regulations. It is also recognized that countries can enact statutory regulations which specify exemptions for tests, according to sealed source type, design, working environment, and activity (e.g., for very low activity reference sources where the total activity is less than the leakage test limit).

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
