880 Series Source Projectors
Specifications
Applications
Model 880 Series exposure devices are used for industrial applications of gamma radiography, mainly with Iridium - 192, to inspect materials and structures in the density range of approximately 2.71-8.53g/cm3. Low energy isotopes can be accomodated to permit radiography of materials and structures of thin sections of steel and low density alloys.
The 880 series exposure devices are also designed for use with low activity sources with high photon energies for mass absorption (gamma scanning) studies of high density materials up to 18.7g/cm3.
Exposure device
Sentinel Model 880 Delta, ELite and Omega source projectors are portable, lightweight and compact industrial radiographic exposure devices. The exposure device body consists of a titanium "S" tube and cast depleted uranium (DU) shield contained within a 300 series stainless steel tube with stainless steel discs welded at each end forming a cylinder shaped housing. The discs are recessed to provide protection for the rear mounted locking mechanism and front mounted outlet port.
The horizontally oriented design allows the locking mechanism, source assembly connector and outlet port to be easily operated, simplifying the connection of source guide tubes and projection sheats. The internal void space of the housing is filled with rigid foam to prevent the ingress of water or foreign material, but is open to atmospheric pressure.
The exposure device body, containing the DU shield, locking mechanism, outlet port, protective covers and required labels, comprises the radioactive material transport Type B package.

| Inspection Requirements | Perform daily pre-operational inspection for any obivious damage to the system. See device operation and maintenance manual for detailed maintenance requirements. | ||||||||||||||||||||||
| 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.
See service operation and maintenance manual for detailed maintenance requirements.
