REGISTRY OF RADI0 ACTIVE SEALED SOURCES AND DEVICES SAFETY EVALUATION OF SEALED SOURCE NO.:
NR460S1290 DATE:
June 29, 1967 PAGE 2 0F 2 SEALED SOURCE TYPE:
Sealed Source DESCRIPTION:
The source consists of a stainless steel bar with a 1/8" slot milled 0.2" deep.
l The slot is covered' with a 0.001" stainless steel window sealed by gold brazing.
The source is filled through a 1/16" copper tube silver brazed through a hole in the back of the source. This tube is crimped and silver brazed after filling.
The active dimensions of the source are 1.5" by 1/8". The overall dimensions are 3.37" long, 0.38" wide and 0.3" deep.
Flanges 1/2" long on each end provide for mounting the source.
Each flange has a #24 (0.152) hole; the holes are 3" apart center-to-center.
i LABELING:
The source is labeled with: Manufacturer's name, Isotope, Quantity, Model and i
Serial Numbers, and Date.
QUALITY ASSURANCE AND CONTROL:
Each source is subjected to a pressure test (minimum of 3 ',imes filling pressure) prior to filling.
The completed source is confined to a closed container for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and the air is monitored for krypton-85 activity.
LIMITATIONS AND/OR OTHER CONSIDERATIONS OF USE:
The device this source is used in should provide protection for the filling tube which projects from the back of the source.
