DEVICE TYPE:
Radiographic Exposure Device DESCRIPTION:
L The-device consists of a' depleted uranium shield and polyurethane filler enclosed in an 1/8" (3.18 mm) steel housing constructed by rolling a.right circular cylinder, and arc welding two circular endpieces.
j A zircaloy "S"
tube extends through.the uranium shield.
At one end is a lock box through which the source pigtail cable and male l
. half of the' quick disconnect-connect connector protrude-(S-16).
l The "A" used in the suffix of'the model number indicates a
)
modified lock box.
The purpose'ofLthe' change in'the design of the lock box is primarily one of safety, which assures that the
^
- lock plunger cannotl b'e depressed -into. the" lock position without the source being in a; shielded position.
It also requires that a connection be made before the source can be cranked out into the exposed position, since.itcis necessary to apply back pressure by use of the control' cable'to permit'~the plunger to be placed in an
' unlocked position..The? drive cable conduit. (30 ' [9.14 m]
j y
minimum)--is threaded into the lock box af ter removing the protective screw cap)
)
The depleted uranium shield (approximately'200 lbs [90 kg]) is L
. secured in place by-two steel. webs inside the steel cylinder.
-l The' casting is coated with'approximately 1" (2.54 cm) of asbestos cement for fire protection of the uranium shield in the event
-that the device has to be opened with a torch; the polyurethane
~ filler acts as a cushion between the casting and the housing.
'The complete device is mounted on wheels which allows easy movement of the device.
The tires and supporting boss are welded to the device housing, and two (2) 8" (20.32 cm) tires and rims i
L are mounted.
The device is fitted with a pipe handle constructed of 1" (2.54 cm) steel pipe.

i i
To provide' additional ease of movement due to its heavy weight, j
two (2) 1-1/2" (3.81 cm) 'lif ting eyes are welded to the top of
{
the device.
The outside exterior dimensions are 16" (40.64 cm) in diameter, by 12" (30.48 cm) high, excluding the handle and wheels.
LABELING:
The device bears the manufacturer's label which specifies that the device contains 200 pounds (90 kg) of depleted uranium.
The label also specifies the isotope, activity, date of calibration,-
source serial number and states " Danger, Do Not Handle, Radioactive Material.
Notify Gamma Industries, Baton Rouge, Louisiana, or Civil Authorities."
EXTERNAL RADIATION LEVELS:
The source within the device is greater than 4" (10.16 cm) to the
-outer-surface of the device.
Utilizing the maximum possession
]
quantity _of Cobalt-60 (22.8 Ci'[843.6 GBq)) for field use, the following dose rates were obtained with a calibrated ionization chamber:
Surface Dose Rate Source in Shielded Position Dose Rate 1-m from Surface (mrem /hr)

LIMITATIONS AND/OR-OTHER CONSIDERATIONS OF USE:
.i The manuf acturer: furnishes an operating and maintenance manual'
. which_ includes' step-by-step instructions for using the exposure l
. device.
This device is very similar in design to the Gamma Industries Century exposure device ~; the difference being that the Gammatron is larger and more heavily shielded.
Cobalt-60 source exchange by the licensee is permitted bp using a Gamma Industries C-8 source exchanger.
J The license for radioactive materials should. include provisions for'200 lbs (90:kg) of depleted uranium, i
- SAFETY-ANALYSIS ~
SUMMARY
The Model Gammatron 20-A device is no longer manufactured or -
distributed by Gamma Industries,_ Inc. and Gamma Industries, Inc.
t
'is no longer in' business.
Therefore, the.. registration i'
certificate is being converted to an inactive registration certificate.

SAFETY ANALYSIS'
SUMMARY
(Cont ' d) -
The device was originally approved for licensing purposes by the Louisiana Division of Radiation Control.
NRC attempted to obtain copies of all information submitted by the registrant in support of the evaluation..However, NRC could not locate'all the information.
Therefore, no safety evaluation'of the device was performed as part of the: conversion of-the certificate to inactive status.
