The main purpose of sealed source leak testing is to determine, qualitatively, the integrity of a sealed source capsule for leakage. All sealed source leak testing (except where indicated by an asterisk (*) below) is performed in accordance with the Canadian Nuclear Safety Commission’s (CNSC) Licence Application Guide: Nuclear Substances and Radiation Devices (REGDOC-1.6.1), Appendix AA: Regulatory Expectations for Leak Testing of Sealed Sources, dated May 2017. Swipes or cotton swabs (one ended) are supplied by BTI as part of the testing kit. Alternatively, the end user may forward their own swipes up to a maximum diameter of 5 cm, provided they include a completed BTI Leak Test Sampling Certificate.
