DAILY INSPECTION INSTRUCTIONS
3.1
Introduction
The QSA Global, Inc. Model 880 Delta, Sigma, Elite and Omega radiographic exposure devices provide
innovation to the most widely used family of radiographic exposure devices utilized for on-site gamma
radiography. The Model 880 Series exposure devices are portable, lightweight and permit use of several
different isotopes commonly needed by the nondestructive testing community.
The Model 880 is primarily designed for use with Iridium-192 sources for radiographic inspection of steel
and light alloys. Due to the advancements in radiographic inspection techniques, additional source
assemblies for the Model 880 Series devices are available. See Section 1 – Technical Specifications, for
a complete list of sources and accessory equipment designed for use with the Model 880 Series devices.
The USNRC and international regulations require routine inspections to ensure that industrial radiography
equipment is operating safely and properly. Design of the Model 880 Series devices includes inherent
safety features and quality construction to ensure the highest degree of quality, safety, reliability and
durability.
Care should be taken to prevent radiological incidents that can occur from neglect, accidental damage,
abuse and lack of inspection and maintenance.
The following instructions should be followed carefully to ensure safe and proper operation of this
equipment.
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 stainless steel stop-ball and a stainless
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.
