BS ISO 9978:2020 pdf free.Radiation protection- Sealed sources- Leakage test methods.
BS ISO 9978 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[1Z] 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).The test programme for test and production sealed sources should be considered as part of the design process and validated or justified as appropriate to demonstrate its effectiveness and sensitivity. This process may include the analysis of historic data.The tests described in this document shall be designed, validated and carried out by competent and qualified persons who have demonstrable appropriate training in the applied test methods. For test methods by radioactive means, the persons shall also have appropriate training in radiation protection and measurement.NOTE 1 Qualification and certification methods for non-destructive testing personnel can be found in ISO 9712[2].An evaluation should be made of uncertainty in the case of non-binary test results (e.g. radiation measurements on immersion test samples) and taken account of in sentencing the result.BS ISO 9978 pdf download.
