Page 3: Introduction
1. INTRODUCTION The VOX 100 Isotope Projector was designed to be used for Industrial Radiography to determine the internal soundness of materials and structures, without destroying the product’s usefulness, thereby assuring the satisfactory performance for which the product was intended. Non-Destructive Testing (NDT) is used in many different spheres of industry, including but not limited to: Oil and Gas, Ship Building, Aviation, Power Generation and General Construction.
Page 4: Technical Descriptions
Whenever this Projector and accompanying equipment are used it is strongly advised that all requirements are followed and applied as laid out in this Operating Manual. All regulations regarding Radiation Safety must also be adhered to at all times! 2. TECHNICAL DESCRIPTION 2.1 Technical Specifications Authorized contents: Co-60...

Note: The Projector package doesn't include the Sealed Radioactive Source. The Sealed Radioactive Source is supplied according to individual order following the Sealed Radioactive Source Order procedure set out by the relevant Authorities. 2.3 Description VOX 100 Isotope Projector The digits in brackets refer to Figure 4 on page 7. The Projector consists of the following basic parts: The Radiation Shielding Unit (1&...

Page 8 Guide Tube The Guide Tube is used to guide the Source Assembly to the radiographic focal point where the Source Terminal and/or collimator are securely attached. The Guide Tube consists of the following basic parts: Guide Tube Coupling, Guide Tube and Source Terminal.
Page 9: Operation
Upon connecting the Winding Mechanism to the Projector, the Winding Mechanism Coupling releases one of the Source Securing Mechanisms. Source Assembly Securing Mechanism The Source Assembly Securing Mechanism is designed in such a way that it requires three independent safety devices to be activated / connected before the Projector can be operated and the Source Assembly moved out of its secured position to the point of exposure.
Page 10 Work Site or Location Always ensure that Industrial Radiography only takes place in a properly secured and restricted area with all appropriate barriers and warning signs required by local regulations in place. Distance As the radioactive source emits high levels of radiation once it is out of its secured position, it is very important to keep the distance between the radiographers and the point of exposure as far as possible.

Guide Tube 1. The Coupling is not damaged or severely worn, is properly attached to the Guide Tube and can be connected to the Projector safely. 2. The Source Terminal is not damaged or worn in any way, including the threads on both the Source Terminal as well as its mating female thread on the Guide Tube.

Page 13 Press the Locking Pin on the front of the Projector in order to remove the Front Protective Cap (Fig. 6). Now pull the Front Protective Cap out by hand and insert it into its storage hole as shown below (Fig. 7).

Page 14 Remove Rear Protective cap and secure it by inserting it into its holder. Lay out the Winding Mechanism Hoses as straight as possible ensuring maximum distance between the Projector and operator. To prevent the Winding Mechanism Hoses being damaged whilst in use, ensure that they are not laid out in walkways, driveways or where there is a danger of falling objects.
Page 15 Figure 11 Figure 12 Step 4 – Exposing and retracting of the Source Assembly Before exposing, ensure that the following is in place: radiation control area barriers, no person/s is inside these barriers and all legislative requirements are in place and met.
Page 16 The Source Assembly Locking Mechanism will automatically lock the Source Assembly in the secured position. The Source Assembly Indicator now shifts from Red to Yellow. Step 5 - Confirmation survey and locking of the Projector Approach the Isotope Projector cautiously while observing the Survey Meter. Ensure that the Source Indicator is yellow when approaching the Projector.

Source) is 2 years or 25000 cycles, whichever comes first, and should be replaced accordingly. The old Source Assembly will then be shipped back to Oserix or it’s local distributor for disposal of the decayed radioactive source and for inspection and re-certification of the Source Assembly.
Page 18 Connect the other end of the Transfer Tube to the Transport Container as described in the container’s operating instructions. Once the Transport Container is ready, proceed to eject the Source Assembly as described in Chapter 4, Step 4. Use a survey meter to confirm that the Source Assembly is secured inside the Transport Container.
Page 19: Inspection
6. Inspection Please pay special attention to this chapter. It is of utmost importance that all inspection procedures are followed and adhered to in full. Failing to do so could result in premature equipment failure, thus compromising safety and productivity. Important Notice In addition to the inspections described below and where specified by National Regulations, the owner of this equipment is required to send the equipment for...
Page 20 Mechanism are clean. Only use cloths that are lint free, wetted with alcohol, to clean your equipment. Important Notice Under no circumstances should any of the equipment be cleaned with solvents, degreasing fluids or any other liquid. Do not lubricate the equipment with oil as dirt will stick to the oil and get transferred into the Winding Mechanism and Projector.
Page 21: Maintenance
7. Maintenance In order for the Exertus VOX 100 Projector to maintain its high safety standards, it is important that maintenance be performed by the manufacturer or accredited service provider at regular intervals. This maintenance should be performed annually or immediately after any repairs were carried out on the projector.
Page 22: Problem Solving
Evacuate the area immediately to a distance that does not pose such a significant risk of exposure. Establish and adjust the Restricted Area Boundary to ensure that the measured dose rate does not exceed 2mR/hr (20µSv/hr) at the boundary lines. Do not allow anyone to enter this area.
Page 23 Once the Guide Tube is removed the Emergency Shipping Plug can be inserted into the outlet port of the Projector and screwed onto the Guide Tube Connector Fitting. The Ballpoint can now be disconnected from the Female Connector. Guide Tube cannot be connected or disconnected. Situation The Locking Pin is stiff or cannot be pushed down to connect / disconnect the Guide Tube.
Page 24 Action • Check that the Guide Tube and Winding Mechanism are correctly connected as described in chapter 4. • Also ensure that the Corbin Lock is fully unlocked. Source Assembly Securing Mechanism fails to lock. Situation After retracting the Source Assembly and verifying with a survey meter that the Source Assembly is indeed back in the shielded position, the Source Assembly Securing Mechanism fails to engage and lock the Source Assembly in the secured position.
Page 25: Disposal Of Radioactive Material & Contact Details
The Projector shielding is of Depleted Uranium which is also required to be disposed of in the proper manner. Oserix can also provide such a disposal service. After disposal Oserix will issue a “Radioactive Material Disposal Certificate”.
