September 8, 1995 PAGE 2 OF 3 SEALED SOURCE TYPE:
Sealed Source DESCRIPTION:
The source consist of solid iridium metal encapsulated in stainless steel.
It is a single encapsulation sealed by heliarc welding.
Overall dimensions are 0.250" (6.4 mm) in diameter by 0.587" (1.5 cm) in length.
The source has a 0.07" (1.7 mm) diameter hole in which the manufacturer fastens an identifying tag.
The source has a window thickness of 0.016" (.04 mm).
DIAGRAM:
See attachment 1.
LABELING:
Each source is engraved with its icotope, activity, and date of assay.
The source tag attached to the source includes model number, serial number, isotope, activity, and date of assay.
PROTOTYPE TESTING:
The source was not prototype tested since is design and manufacture differed from the AECL C-164 source in that it contained Ir-192 rather than Co-60.
LIMITATIONS AND/OR OTHER CONSIDERATIONS OF USE:
- The sealed source may be used by specific licensees of NRC or Agreement States.
- Handling, storage, use, transfer, and disposal:
To be determined by the licensing authority.
- The sealed source shall be leak tested at intervals not to exceed 6 months using techniques capable of detecting 0.005 microcurie (185 Bq) of removable contamination.
- This registration sheet and the information contained within the references shall not be changed without the written consent of the NRC.

SUMMARY
\\
Existing AEC/NRC files (registration files, license files, NUDOCS, and archives) concerning these products were examined for information that supports registration of the products.
Copies of all applicable information located is included in this file.
{
{
The manufacturer, LFE, was also asked for additional information concerning the products.
However, man the products have not been distributed for years, y of g
the product lines were sold in the late 1960's, or 9
and j
LFE provided all additional information they have concerning the products.
NRC has transferred the registration certificates to i
inactive, as requested by LFE, and continues to conclude the products are acceptable for licensing-purposes based on AEC's original evaluation of the products and the operational history of the products.

Dear Mr. Prendergast:
This letter is in reference to your letter dated August 6,1991, which requested that we transfer the registration certificates listed in column 1 of to inactive status. The certificates have been transferred to inactive status as you have requested.
Please note that transfer of the registration certificates to inactive status means the sources or devices included on the certificates may no longer be commercially distributed.
The registration numbers for the certificates have been changed.
specifies the old registration number, the new registration number, and the model numbers.
Please note that some old certificates have been combined into one new inactive certificate.
In addition, two registration certificates have been deleted from the system since they were duplicates of other certificates.
Please review the registration certificates (copies enclosed in their entirety and notify us immediately if there are any errors or) omissions.
If you have any questions, please call me at (301) 415-7868 or Mr. Steven Baggett at (301) 415-7273.
Sincerely,
/S/
