SAFETY EVALUATION OF SEALED SOURCE NO.: NR4605136U DATE:
February 08, 1968 PAGE 2 0F 2 SEALED SOURCE TYPE:
Beta Gauge Source DESCRIPTION:
The source consists.of promethium-147 in the form of nickel plated 3M microspheres i
encapsulated in aluminum and secured in a stainless steel holder with overall dimensions of 1.375" diameter and 0.875" height.
The active area is 1" in diameter and is slightly lower than the 3/16" wide rim of the source. Height of the body of the source is 0.375" with the remainder of the overall height taken up by a 0.25" diameter, threaded protrusion at the bottom of the source.
The nickel plated microspheres are pressed into a 63 mil thick aluminum sheet to a depth greater than their radius.
Loose microspheres are removed and the 1" diameter sheet is then wrapped in 1 mil aluminum foil which is sealed at the back l
by pressing a screen into the lapped foil ends and covering with epoxy cement.
This product is then dropped into the stainless steel housing followed by a press fit stainless steel plug which is sealed in place with epoxy cement.
LABELING:
The back of the source (plug) is engraved with "Pm-147, Model 3L2E", the source activity in millicuries, the date and source serial number.
PROTOTYPE TESTING:
As described for 3L2A, 3L2B, and 3L2C.
QUALITY ASSURANCE AND CONTROL:
1.
Smear test aluminum disc after pressing in the microspheres.
2.
Smear test completed source immediately after fabrication and again immediately prior to shipment.

In accordance with a July 25, 1991 telephone conversation between Mr. Melvin R.
Peters, 3M, and Mr. John W.

The manufacturing of these sources either has been, or will have been, permanently discontinued by September 30, 1991.
It is our understanding that upon termination:
1.
The registrations will become part of NRC's inactive file, but present users of the sources may continue to use them.
2.
3M can accept the sources for disposal and leak testing, but cannot refurbish or repair them.
3.
3M, on a best effort basis, will provide the NRC l
