Introduction:==
The SPEC Model 2-T is a radiographic exposure device which has been in service five or more years since. its original approval.
To our knowledge, there has been no signifi-cant incidents during either shipping or radiography.
Packaging:
The general description and operational features remain virtually unchanged since the original approval.
The exposure device (gan:ma ray projector) consists primarily of a stainless steel housing and internal steel bracing of all welded construction.
The depleted uranium sbield incorporates a Zircalloy "S" tube.
The source is secured in safe position l
by a combination of components including a plunger type lock, a locking ball on the pigtail assembly, a lock insert to prevent removal from the rear of the unit in either the locked or I
unlocked mode, and a shipping plug.
The unit resembles a rectangular box approximately 12.5" long, 4.4" wide, and 4.4",
high (excluding aluminum handle).
Gross weight is approximately l
43 pounds.
l The SPEC 2-T is constructed in accordance with the Source C.
Production and Equipment Co., Inc. drawings as submitted in the application in 1975 and with the enclosed revised, consolidated drawings.

' Nr,vember 21, 1980 Pcg2 2 Contents:
The SPEC 2-T will be used for industrial radiography and for the shipping of special form sources for radiography.
The device will contain one source only and the maximum activity would be 175 curies nominal of Iridium-192 without the use of an overpak.
Since the unit is approved for 200 curies nominal for industrial radiography, a convenience overpak is used for contents exceeding 175 curies.
Sources shipped in the SPEC 2-T meet the requirements of special form as defined in 10 CFR Part 71.
Name Plate:
The name plate is fabricated of stainless steel to meet the fire test of 10 CFR 71.
Testing:
'dypothetical Accident Conditions:
An actual 2-T was subjected to free drop, thermal, and puncture tests per 10 CFR 71 and resulted in only very minor deformation with no loss of shielding integrity or effectiveness of locking mechanisms.
Test results and photographs were submitted with the original application.
Sincerely, Source Production & Equipment Co., Inc.
