REGISTRY OF RADIOACTIVE SEALED SOURCES AND DEVICES SAFETY EVALUATION OF SOURCE (AMENDED IN ITS ENTIRETY)
NO.: NR-220-S-830-S DATE: September 11, 2003 PAGE 2 OF 2 (Previously NR-0169-S-124-U)
SOURCE TYPE: Irradiator Source DESCRIPTION:
The AECL Model C-133 sealed source is a singly-encapsulated, fusion-welded, (#316L) stainless steel capsule. Originally its length was to vary from 9/16" to 36" and diameter to vary from 0.18" to 1.223". It's wall thickness is 0.025". The physical dimensions of the capsule have been subsequently modified to include a diameter of up to 1.254" and a length only up to 18" (longer maximum lengths require special agreement with AECL).
This source may contain jacketed slugs, unjacketed slugs, and nickel plated pellets. This capsule may be used in other AECL capsules. It is tested for contamination by two wipe tests (dry) taken seven days apart (0.005 microcurie).
