Industrial radiography is a specialized branch of nondestructive testing that uses ionizing radiation to inspect materials, components, and structures without causing damage. Unlike medical radiography, which focuses on human anatomy, industrial radiography evaluates welds, castings, pipelines, pressure vessels, aerospace components, and critical infrastructure. It plays a vital role in manufacturing, construction, energy production, transportation, and national security.
Industrial radiographers must demonstrate strong technical skill, strict adherence to radiation safety, and the ability to work in challenging environments. The field offers structured certification pathways, regulatory oversight, and a robust professional framework supported by associations and scholarly resources.
Licensure and Regulatory Requirements in Industrial Radiography
Industrial radiography is one of the most heavily regulated uses of ionizing radiation due to the high activity of radioactive sources and the potential for occupational exposure.
Regulatory Oversight
- U.S. Nuclear Regulatory Commission (NRC)
- Agreement State Radiation Control Programs
- Department of Transportation (for transport of radioactive materials)
- Occupational Safety and Health Administration
- International Atomic Energy Agency (global standards)
Common Licensure Requirements
- Completion of formal radiation safety training
- On‑the‑job training under a certified radiographer
- Passing written and practical certification examinations
- Compliance with federal and state radiation regulations
- Maintaining dosimetry and exposure records
- Annual safety refreshers and audits
Industrial radiographers must be authorized users of radioactive materials or certified to operate x‑ray generators, depending on the modality used.
Certification Examinations
Certification in industrial radiography is typically obtained through nationally recognized nondestructive testing organizations. Certification validates a radiographer’s knowledge of radiation safety, imaging techniques, and material evaluation.
Major Certification Bodies

- Industrial Radiography Radiation Safety Personnel certification programs
- International Organization for Standardization (ISO) NDT certifications
- State‑specific industrial radiography certifications
Certification Levels
- Level I: Performs radiography under direct supervision
- Level II: Independently conducts radiography, interprets images, and trains Level I personnel
- Level III: Develops procedures, oversees programs, and provides expert consultation
Certification Examination Content
- Radiation physics and safety
- X‑ray and gamma ray equipment operation
- Radiographic techniques and exposure charts
- Film and digital image interpretation
- Material defects and discontinuities
