Industrial Radiation Safety, Radiography, and Film Interpretation
Industrial radiography is a nondestructive testing technique using high-energy radiation to penetrate an object resulting in an image on a piece of radiographic film. Before any worker can perform industrial radiography, every jurisdiction requires completion of a minimum of 40 hours of industrial radiation safety. Radiation Safety prepares the worker for a career in industrial radiography so that he or she can protect all radiation workers and the general public from the effects of ionizing radiation.
Industrial radiography technicians use the precepts learned in their Radiation Safety course to work safely while using these invisible dangerous rays of energy.
Industrial Radiography courses, either Level I or Level II, instruct the radiographer on how to produce radiographs of high quality using geometric principles of enlargement, image production, processing chemistry, and others.
Industrial radiography is, perhaps, one of the most versatile and widely used inspection techniques because it produces a fixed image that is easily understood and widely interpretable.

Ultrasonic Testing
Ultrasonic testing involves the use of high frequency sound waves to determine the condition of a component. These high frequency sound waves, ultrasound, travel along very distinct paths and reflect back to the transducer allowing the technician to “see” inside the part being tested.
There are two primary modes of propagation for industrial ultrasonic techniques, longitudinal beam for determining thickness of the component or some material properties and flaws, and shear wave testing which projects a sound beam in at a refracted angle allowing for the detection of welding or material flaws.
Of paramount importance in ultrasonic testing is the operator’s ability to know where the sound is and to interpret the returned signal that would often indicate a flaw in the material or reduced thickness. Our courses are designed to ensure that you can perform these two crucial functions.
Other modes exist, but are instructed on an “as-needed” basis such as phased array inspection, time of flight diffraction, or guided wave ultrasonics, for instance.
Liquid Dye Penetrant and Magnetic Particle Inspections
Among the most widely utilized non-destructive testing techniques are Magnetic Particle (MPI) and Liquid Dye Penetrant (PT) Inspection.
These techniques are primarily used to find surface breaking discontinuities and, in the case of MPI, some subsurface discontinuities.
Magnetic Particle Inspection of ferromagnetic materials relies heavily on the laws of magnetism possibly first introduced by Aristotle in the mid 300’s BC. Using magnetic fields, small ferromagnetic particles are attracted to leakage fields (defects) and are visible at the accumulation site.
When testing a non-ferromagnetic material, the use of visible or fluorescent dyed oils, which (through capillary action) work their way into surface breaking discontinuities, only to be blotted out of the indication by a powder is the basic premise of Liquid Dye Penetrant Inspection.

Eddy Current Testing
Quickly becoming a cost effective alternative to Magnetic Particle Inspection, Surface Eddy Current Inspection allows for the operator to locate cracks and other surface and near-surface discontinuities without the need for costly removal of non-metallic coatings. Often times, surface eddy current inspection is used to perform a survey and, if a discontinuity is found, the coating is removed and Magnetic Particle Inspection is used to verify the presence of the break.
Other eddy current inspection techniques are used for determining the condition of heat exchanger tubes used primarily in refineries and chemical plants. In this arrangement the Eddy Current Probe coil is most often positioned within the tube after cleaning. Using Eddy Currents, the operator can reliably determine the position of the indication, internal or external, and extent of damage.
Eddy currents are generated when a current conducts into a coil that, in turn, produces a small magnetic field around the coil. This magnetic field produces eddy currents in the metallic material, which can be measured and analyzed.
When the eddy current probe is brought into proximity to a defect, the eddy currents are disrupted causing a deflection of the currents noticed by the pick-up coil and display on the screen.
Visual Inspection
Visual Inspection is the use of the eye to conduct an inspection. Some say that all inspection is, at the heart, a visual inspection. Methods such as Magnetic Particle or Liquid Dye Penetrant are methods that directly use the eye to determine the presence of a discontinuity by increasing the contrast between the inspection surface and the defect.
Visual Inspection should be performed prior to each application of another inspection method to determine, partially, if the inspection should continue. For instance, if, following a visual inspection, a crack on the surface is found, there isn’t much point in applying ultrasonic shear wave.
Many National and International visual inspection certifications exist which rely on the eyes of the inspector to find flaws in many different types of equipment such as:
- API 510 for Pressure Vessels
- API 570 for Pressure Piping
- API 653 for Above Ground Storage Tanks
- AWS CWI for Welding Inspection
Obtaining a good background in Visual Inspection is generally regarded as necessary to make inspection personnel the best that they can be, regardless of the method to be employed.
Industrial Rope Access
ND3’s sister company, AccessRULES offers SPRAT and, soon, IRATA rope access training and certification. There exists a strong synergy between inspection and light trades and rope access as these work methods can be accomplished less expensively and in less time then when using conventional access methods such as scaffolding.
Industrial Rope Access techniques are relatively new, innovative ways to access a worksite that offer significant cost savings when compared to the use of conventional access methods such as scaffolding, spiders, cranes, etc. The access technicians are the workers’ performing the task to be accomplished and as such, exposure to hazards is minimized. Also, the use of Rope Access techniques removes additional hazards more often associated with the workplace such as congestion and tripping hazards.
There are three levels of certification in regards to Rope Access, Level 1, Level 2, and Level 3. ND3, through AccessRULES, offers certification packages designed for each level of competency. After your rope access course is completed, an independent assessor will gauge your skills and may certify you to the appropriate level to a National or International Standard.
Using techniques and tools to abseil, descend, belay, and deviate ropes, you will understand how to keep yourself and others safe while working on the ropes. Ensuring your safety, not only while in a learning environment but while on the job is our first priority; a job that we take very seriously.
Industrial Rope Access training is the foundation to working safely at height in industry and is uniquely suited to work such as NDE and light trades such as insulation removal/reinstatement, blasting, painting, and even welding. With proper training and certification in rope access, you can take your trade, and your career, to new heights.
