Gary Larson has over 40 years of experience performing NDT on pipe welds, cast steel valves, ductile iron castings, and various aerospace industry applications. He is an ASNT Level III certificate holder in Radiographic Testing, Ultrasonic Testing, Penetrant Testing, Magnetic Particle Testing, and Visual Testing. He also holds an ACCP certification in Magnetic Particle Testing and Penetrant Testing.

Mr. Larson has performed X-ray and Gamma-ray radiography using film, amorphous selenium plates, and phosphor imaging plates. Mr. Larson has Ultrasonic Testing experience on various metals, steel welds, and composite materials. In addition, he has extensive experienced in Penetrant Testing using visible and fluorescent penetrant techniques. His Magnetic Particle Testing experience includes techniques using yokes, prods and wet horizontal equipment. He has extensive experience in Visual Testing. 

He worked for 23 years directly in the nuclear industry in piping, welding and valves.  He has worked with Sikorsky Aircraft performing UT, RT, MT and PT at the Bridgeport, Shelton and Stratford plants.  He has performed training in UT, MT, PT and RT for various plants with Sikorsky Aircraft and Pratt and Whitney Aircraft plants.  He is currently a consultant level III for a customer supplying Boeing Parts, and a customer supplying Military parts requiring NAS-410 certification.

ASNT Level III certificates held during the production of online NDT courses taught by Mr. Larson include Magnetic Particle Testing, Penetrant Testing, Radiographic Testing, Ultrasonic Testing and Visual Testing. 

Previous certifications included AWS Certified Welding Inspector, and Electric Power Research Institute Flaw Sizing. Gary is currently a member of ASNT and an active member of the E-07 Committee of ASTM.

Radiographic Testing Level II addresses the required training by documents controlling the certification program such as NAS-410, SNT-TC-1A and NavSea Technical Publication T9074-AS-GIB-010/271. Course content conforms to the training subjects listed in ANSI/ASNT CP-105, Standard Topical Outlines for Qualification of Nondestructive Testing Personnel. When combined with laboratory-type hands-on training under the direction of a Level II or Level III, this course will meet the total hours of training required by the applicable certification document listed above.

The training is divided into thirteen chapters.

1. Review of Level I data; applications of radiography; types of radiation; the atom; isotope production; decay process; measurement of radioactivity; specific activity; half-life; electron volt; energies of gamma sources and x-rays; ions and ionization; scatter radiation
2. ALARA; methods of protection against radiation exposure; inverse square law calculations; shielding and half value layers of different materials; half value layer calculations; posting requirements
3. Preparation for conducting radiation operations; gamma ray equipment; collimator; x-ray tube and operation; personnel monitoring equipment; survey meter operation and types; pocket dosimeter, film badge, OSLD, TLD, RATE ALARMS
4. Radiographic quality; sensitivity, contrast and definition; characteristic film curves; latitude; unsharpness; backscatter; geometric unsharpness; part geometry effects on radiograph
5. Film processing techniques; film structure and speeds; film artifacts; lead screen use
6. Measuring radiographic quality with IQI’s; Types of IQI’s; placement of IQI’s; exposure calculations and charts; film density and measuring of density; determining source to film distance; film viewers
7. Radiographic techniques; IQI placement and shims; Parallax formula; radiograph layout for neatness and accurate information
8. Computed Radiography (CR) and Digital Radiography (DR) terminology, techniques, and equipment handling are discussed; image intensifiers, linear diode arrays, DDA panels, line pair and contrast sensitivity gauges, and spatial resolution are also discussed
9. Terminology discontinuities, defect, false indication, non-relative indication, relative indication; linear vs. rounded indications; classifications of discontinuities; product discontinuities; service discontinuities
10. Welding processes and welding discontinuities
11. Film interpretation and evaluation elements; weld discontinuities; radiographs of actual discontinuities; casting discontinuities
12. Codes; specifications; ASTM reference radiographs; procedures; reports
13. Process control checks; formulas; conversions

This training will meet most certification documents for Level II Radiographic Testing such as SNT-TC-1A, and encompasses the subject matter listed in ANSI/ASNT CP 105 for radiographic testing certification. Please verify that the employer’s written practice (document for certification of NDT personnel) allows for online training. Upon satisfactory completion of all training material and exams, a training certificate will be issued. Please secure this document in a safe location, as it may be needed multiple times throughout your career.

NOTE: Please note the contact hours being awarded for this course.  To meet the training requirements in SNT-TC-1A, CP-189, and NAS-410, the student must complete the eLearning course and the necessary practical lab/hands-on sessions. These lab sessions must be overseen and documented by a Level III to ensure the required training hours are fulfilled.
