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.

Radiography Testing Level I is a foundational course necessary for anyone looking to receive their Level I certification. It 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 twenty-one chapters.

3. Properties of matter; the atom and its parts; elements and periodic table notations
4. Ionization; alpha and beta particles and gamma and x-rays; electron volts; photo-electric effect; Compton scattering; pair production; Units of radiation exposure in air; gamma source emissivity; X-Ray output
5. Gamma radiation; Isotope production; gamma source properties; activity and half-life; calculations for half-life; agreement and non-agreement states; advantages and disadvantages of gamma ray radiography; gamma source projectors; double encapsulation; collimator
6. X-Ray generation; Bremsstrahlung process; Scatter; parts of x-ray tube; intensity and Kv of tubes; heel affect; characteristic x-rays; transformers and generators; rectification; warm up requirements; focal spot size; filtering at the tube; high-energy x-ray sources
7. Radiographic quality; film processing; sensitivity and quality of radiograph; types of IQIs; film structure; film handling, and film artifacts
8. Intensifying screens and cassettes; multiple film load techniques
9. Radiographic sensitivity, contrast, and definition; characteristic curves; latitude; unsharpness; protection and detection of scatter radiation; geometric unsharpness formula and rules of shadow formation
10. Measuring radiographic quality; IQI details and uses; placement of IQI; shims for hole type IQIs; exposure charts; density requirements; step wedge strip for densitometer calibration; calculation of minimum source to film distance
11. Non-film imaging devices; line pair gauge; EN-465 gauge; resolution and contrast sensitivity verification
12. Sources of radiation in society; ionizing radiation; tissue damage mechanism from radiation; radiation exposure units; dose calculation; Code of Federal Regulation (CFR); state and NRC control of radiation licenses; ALARA; dose limits for radiation workers and public; radiation effects and variables; acute and somatic effects; restricted area, radiation area and high radiation area limits and posting requirements; types of facilities
13. Methods of protection against radiation including time, distance and shielding; dose calculation; inverse square calculations and definition; shielding by ½ and 1/10 value layer and definitions and calculations
14. Radiation safety equipment and monitoring devices; survey meter types, calibration and measurement limits; pocket dosimeter; TLD, OSLD and film badges; alarming rate meter; area alarms
15. Required surveys for radiation work; labeling of sites and equipment; gamma ray container types and radiation limits; vehicle requirements for various levels of radiation; truck storage limits; shipping requirements storage surveys
16. Daily and quarterly maintenance checks; leak testing; x-ray machine labels
17. Reports, records and notifications per NRC regulations; licensing requirements
18. NRC training requirements for radiographers and radiation safety officers; periodic observation by RSO
19. 10-CFR-37 regulations
20. Radiographic variables such as changing Ma, Ci, Kv and distance
21. Qualification and certifications documents and SNT-TC-1A review

This training will meet most certification documents for Level I Radiographic Testing such as SNT-TC-1A, and encompasses the subject matter listed in ANSI/ASNT CP 105 outline 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.
