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.
