Are leak tests required for alpha foil sources?
Leak testing requirements for most sealed sources and plated sources are documented in the Sealed Source and Device Registry for the source. The Registry indicates whether the source needs to be leak tested and indicates the required leak test frequency. In addition, 10 CFR 35.67(f)(3) states that “sources containing 0.37 MBq (10 uCi) or less of alpha-emitting material” need not be leak tested. Refer to “Supplementary Information,” Section III, “Summary of Public Comments and Responses to Comments” for 10 CFR 35.67 as published in the Federal Register on April 24, 2002.
