DAILY INSPECTION INSTRUCTIONS

Operational features 1 Source assembly

A sealed source containing the radioactive material is swaged (crimped) to one end of a flexible steel leader, commonly referred to as the source holder or pigtail. A steel stop-ball and a steel connector are swaged to the opposite end of the source holder. The stop-ball provides the means to secure the source assembly within the exposure device's locking mechanism. The source assembly connector provides the means to attach the control cable connector to enable remote projection and retraction of the source assembly. The source assembly connector and projector locking mechanism are designed so that the sealed source cannot be projected from the exposure device unless it has been properly coupled to the control cable connector and the remote control. (See figure 3.1)

DANGER - IMPORTANT WARNING

The source assembly while in an unshielded position and the sealed source containing the radioactive material must NOT be handled under any circumstances. The unshielded source at close proximity can cause serious injury, sickness or death to anyone exposed to it even for a short duration.

All specific model number source assemblies used in the Model 880 are designed and tested for use in accordance to ISO/ANSI and USNRC requirements.

2 Exposure device

The source assembly is shown in the stored position in a titanium ‘S’ tube at the center of the depleted Uranium shield of the exposure device. (See figure 3.2)

A remote control unit is shown with its control cable connector coupled to the source assembly.

High density depleted Uranium shielding is used in the exposure device to provide good radiological protection with minimal weight.
