Construction

 

A depleted Uranium (DU) shield is encased within a welded tubular stainless steel shell with

stainless steel end plates. The interior void space is filled with rigid polyurethane foam.

The exposure device body is encased in an engineered plastic jacket also consisting of the

handle and a base.

 

Materials

 

Titanium ‘S’ tube, DU shield, 300 series stainless steel tubular shell and plate, aluminum,

brass, tungsten and polyurethane.

 

Maximum capacities

 

Delta 150Ci (5.55TBq), Sigma 130Ci (4.81TBq), Elite 50Ci (1.85TBq) of Ir-192.

Inspection requirements

 

Daily pre-operational inspection for obvious damage to the system.

Maintenance requirements

 

Most national regulations require inspection and maintenance of the system at

quarterly intervals. The complete annual servicing ensures the integrity of the system.

Shorter frequencies of inspection and maintenance are required when the system is

operated under severe operating environments. In some cases, the system should be

serviced immediately after certain jobs in severe environmental working conditions.

Operating temperature range

 

-40°F to 300°F (-40°C to 149°C)

 

Source assembly

 

USNRC Model Number: A424-9 source assembly with a doubly encapsulated Ir-192 sealed

source. The IAEA/USDOT Special Form Certificate number is USA/0335/S. Optional isotopes

that may be utilized in the Model 880 exposure devices are listed in this section.

NOTICE

 

This industrial radiography system is used as an exposure device and a Type B(U) shipping

container for AEA Technology QSA, Inc. source assemblies. The purpose of this manual is

to provide information which will assist qualified radiographers in using the Model 880

Delta, Sigma and Elite gamma radiography system. The user must be thoroughly familiar

with this instruction manual before attempting operation and use of this equipment.

In order to use this equipment or perform source changes, users within the USA must be

specifically licensed to do so. Applications for a license should be filed with the Materials

Licensing Section of the appropriate U.S. Nuclear Regulatory Commission regional office or
