9.1 Federal & Agreement State Regulations, Licensing & Radiation Safety Programs

The Dual Regulatory Structure: NRC and Agreement States

Industrial radiography in the United States is governed under a coordinated dual regulatory structure established by the Atomic Energy Act of 1954, as amended. The primary federal authority resides with the U.S. Nuclear Regulatory Commission (NRC), codified in Title 10 of the Code of Federal Regulations (10 CFR). Specifically, 10 CFR Part 34 governs licenses and radiation safety requirements for industrial radiography, while 10 CFR Part 20 establishes foundational standards for protection against ionizing radiation.

Under Section 274 of the Atomic Energy Act, the NRC is authorized to enter into formal bilateral agreements with individual states. Through an Agreement State contract, the Governor of a state certifies—and the NRC Commission confirms—that the state possesses an adequate and compatible radiation control program. Upon execution of this agreement, the NRC relinquishes its regulatory and licensing authority within state borders over three primary categories of radioactive materials:

1. Byproduct Material: Radioactive material yielded in or made radioactive by exposure to radiation incident to the process of producing or utilizing special nuclear material (such as Iridium-192, Cobalt-60, and Cesium-137 produced in reactors).
2. Source Material: Uranium or Thorium in any physical or chemical form, or ores containing at least 0.05% Uranium or Thorium by weight (including depleted uranium used as internal shielding in radiography exposure devices).
3. Special Nuclear Material (SNM) in quantities not sufficient to form a critical mass: Enriched uranium and plutonium.

Division of Jurisdiction

While an Agreement State assumes direct licensing, inspection, and enforcement authority over private radiography contractors operating within its borders, the NRC retains absolute, non-delegable jurisdiction over specific entities nationwide:

• Federal Facilities and Military Enclaves: Any federal installation, military reservation, national laboratory, or naval shipyard located within the geographic boundaries of an Agreement State remains under sole NRC jurisdiction unless exclusive federal jurisdiction has been formally ceded back to the state.
• Commercial Nuclear Power Plants: Radiography conducted within the licensed protected area of commercial nuclear reactors (regulated under 10 CFR Part 50 and Part 52) falls entirely under federal NRC oversight.
• Offshore Waters (The Outer Continental Shelf): Industrial radiography conducted on offshore oil and gas platforms, drilling rigs, pipelay barges, and subsea tie-ins in federal waters—defined as ocean waters beyond state territorial limits (generally beyond 3 nautical miles, or 3 marine leagues in Texas and the Florida Gulf coast) out to the 200-nautical-mile Exclusive Economic Zone—is regulated exclusively by NRC Region IV under the Outer Continental Shelf Lands Act.

Jurisdictional Scope Hierarchy:
  NRC Direct Oversight ──> Non-Agreement States, Federal Enclaves, Nuclear Plants, Offshore Waters (>3 mi)
  Agreement State Oversight ──> State-licensed commercial facilities, fabrication shops, local field sites

State regulations must maintain compatibility with NRC regulations. While an Agreement State may enact rules that are more stringent than federal baselines (such as mandating more frequent refresher training or lower administrative action levels), state regulations cannot be less restrictive than NRC standards.

Cross-Border Operations and Reciprocal Recognition (10 CFR 150.20)

Industrial radiography contractors frequently mobilize across state boundaries to perform non-destructive examination on interstate pipelines, petrochemical refineries, bridges, and offshore platforms. When an Agreement State licensee intends to perform work inside an area under NRC jurisdiction (such as in a non-Agreement State or on a federal military base), the company is not required to undergo a full, multi-month specific licensing process. Instead, operations are authorized under the general license for reciprocity codified in 10 CFR 150.20.

The 180-Day Rule and Filing Mechanics

Reciprocity grants a temporary legal authorization subject to strict statutory constraints:

1. 180-Day Annual Limitation: An Agreement State licensee may operate within NRC jurisdiction under reciprocity for a cumulative maximum of 180 calendar days per calendar year. Any portion of a calendar day spent performing radiography or storing radioactive materials within NRC jurisdiction counts as a full operational day. If an ongoing project requires work exceeding 180 calendar days, the licensee must submit a formal application and obtain a full, specific NRC radioactive materials license.
2. NRC Form 241 Submission: To initiate reciprocity, the licensee must complete and submit NRC Form 241 ("Report of Proposed Activities in Non-Agreement States, Areas of Exclusive Federal Jurisdiction, or Offshore Waters") along with the prescribed reciprocity application fee (under 10 CFR 170.31 Category 16) and a copy of the home state radioactive material license.
3. 3-Day Advance Notice: Under 10 CFR 150.20(b)(1), NRC Form 241 must be filed with the appropriate NRC Regional Office at least 3 days before engaging in the activity at any temporary job site. If emergency pipeline or refinery repairs require immediate radiography, the licensee must contact the regional office via telephone or facsimile, obtain verbal approval, and file an emergency Form 241 immediately.
4. Mandatory Documentation on Site: The radiography crew must maintain hard copies of the filed NRC Form 241, the Agreement State specific license, company operating and emergency procedures, and all applicable calibration and utilization records directly on the field truck at the temporary job site.

Radiographer Qualification and Certification Mandates (10 CFR 34.43)

Because industrial radiography involves unshielded exposure of sealed radioactive sources possessing activity levels sufficient to deliver lethal doses within minutes, personnel qualification standards are among the most stringent in the industrial trades. Under 10 CFR 34.41, an exposure device may never be operated at a temporary job site by a lone individual. A minimum two-person crew is legally mandatory: at least one certified radiographer and one qualified radiographer or radiographer's assistant. The second individual must be physically present, capable of observing radiography operations, and trained to initiate immediate emergency recovery protocols should the lead radiographer become incapacitated.

Two-Person Crew Structure (10 CFR 34.41):
  [Certified Radiographer] <── Immediate Sight & Hearing ──> [Qualified Radiographer or Assistant]
         │                                                                   │
         ▼                                                                   ▼
  Manipulates remote crankout,                                    Maintains constant visual surveillance
  performs post-exposure surveys                                  of boundary perimeter & interlocks

Step-by-Step Radiographer Certification Pipeline

Two separate rulebooks stack here, and IRRSP candidates must keep them apart:

• 10 CFR 34.43(a)(1) — the NRC requirement — states that an individual may not act as a radiographer until they have received training in the subjects listed in 34.43(g), completed a minimum of 2 months of on-the-job training, and are certified through a radiographer certification program by a certifying entity meeting appendix A to part 34. The NRC does not specify a classroom hour count or an hour-based OJT count.
• The ASNT IRRSP program document — the certifying entity's own eligibility criteria — is where the familiar numbers come from: 40 hours (6 days) of radiation safety training for every exam route, plus documented experience of 200 hours / 29 days for the Radioactive Materials (RAM) route or 120 hours / 18 days for the X-ray (XR) route (both for the Combo route). ASNT counts one day as at least seven hours, accumulated or in a single day.

With that distinction made, the practical pipeline is:

1. 40 Hours of Formal Radiation Safety Training (ASNT eligibility requirement), covering the 10 CFR 34.43(g) subjects:
   • Fundamentals of radiation protection (time, distance, shielding, inverse-square law, ALARA philosophy).
   • Characteristics of ionizing radiation (half-life, decay kinetics, gamma ray vs. X-ray energies).
   • Units of radiation dose and radioactivity (Roentgen, rem, rad, Curie, Becquerel, Sievert, Gray).
   • Radiation detection instrumentation (survey meter operation, daily checks, GM detectors, ion chambers).
   • Radiographic exposure devices and ancillary gear (S-tube cameras, drive cables, guide tubes, collimators, source changers).
   • Detailed review of 10 CFR Parts 19, 20, 34, and DOT 49 CFR transportation rules.
   • Case histories of radiographic accidents, stuck source incidents, and critical human errors.
2. Documented Experience / On-the-Job Training: 10 CFR 34.43(a)(1) requires a minimum of 2 months of on-the-job training. ASNT's own eligibility criteria express the same idea in hours:
   • 200 hours / 29 days of documented experience for the Radioactive Materials (RAM or Gamma) exam (isotope exposure devices containing Ir-192, Co-60, or Se-75).
   • 120 hours / 18 days of documented experience for the X-ray (XR) exam (cabinet, directional, or crawler X-ray tubes).
   • Combo (RAM/XR) candidates must satisfy both.
   • Experience must be verified by a current Radiation Safety Officer or company personnel officer, and while the trainee actually manipulates equipment they work under the personal supervision defined in 10 CFR 34.46.
3. Independent Third-Party Written Examination: The candidate must pass a comprehensive, standardized certification exam administered by an independent certifying entity recognized by the NRC under 10 CFR 34 Appendix A, such as the American Society for Nondestructive Testing (ASNT) Industrial Radiography Radiation Safety Personnel (IRRSP) program or an authorized Agreement State certifying board.
4. Practical Competence Demonstration: The candidate must demonstrate practical, hands-on competency to the Radiation Safety Officer (RSO), executing radiographic exposures, boundary postings, remote crankouts, 360-degree survey sweeps, daily inspections, and simulated emergency response.
5. Annual Refresher Safety Training: Under 10 CFR 34.43(d), the licensee must provide refresher safety training for each radiographer and radiographer's assistant at intervals not to exceed 12 months, covering regulatory revisions , ALARA operational performance, equipment malfunctions, accidents or errors observed, and emergency procedures.
6. Semi-Annual Job-Performance Inspections (10 CFR 34.43(e)): The RSO or designee must run an inspection program covering the job performance of each radiographer and radiographer's assistant, including observation of performance during an actual industrial radiographic operation at intervals not to exceed 6 months. Under 34.43(e)(2), if a radiographer or assistant has not participated in a radiographic operation for more than 6 months since the last inspection, they must re-demonstrate the 34.43(b)(3) (radiographer) or 34.43(c)(2) (assistant) knowledge by a practical examination before next participating. Where a single individual serves as both radiographer and RSO and performs all radiography, 34.43(e)(4) waives the inspection program.

Radiation Safety Officer (RSO) Authority and Responsibilities

The Radiation Safety Officer (RSO) serves as the licensee's primary regulatory and administrative executive responsible for radiation protection. Codified in 10 CFR 34.42 and 10 CFR 20.1101, the RSO must possess formal qualifications:

• Completion of the training and testing requirements of 10 CFR 34.43(a) (10 CFR 34.42(a)(1)).
• 2,000 hours of hands-on experience as a qualified radiographer in industrial radiographic operations (10 CFR 34.42(a)(2)). Part 34 sets no additional continuous-service requirement.
• Formal training in the establishment and maintenance of a radiation protection program (10 CFR 34.42(a)(3)). The Commission may accept alternatives under 34.42(b) where the candidate has appropriate ionizing-radiation training or experience plus adequate formal program-management training.

Primary RSO Administrative and Safety Duties

Key RSO Responsibilities (10 CFR 20.1101 & 10 CFR 34.42):
  ├── Establish, maintain, and enforce written Radiation Protection Program
  ├── Exercise unconditional Stop-Work Authority over unsafe radiographic operations
  ├── Review personnel dosimetry records (Form NRC-5) and investigate ALARA exceedances
  ├── Supervise quarterly source physical inventories and 6-month leak testing
  ├── Audit all radiographers in the field at semi-annual (6-month) intervals
  └── Direct all emergency source recovery operations and regulatory notifications

Under 10 CFR 20.1101(c), the licensee must periodically — at least annually — review the radiation protection program's content and implementation; in a radiography licensee that review is normally conducted and documented by the RSO. Most importantly, the licensee's executive management must grant the RSO unconditional stop-work authority. If an operational hazard, boundary violation, or equipment malfunction arises in the field, the RSO has the legal authority to shut down operations immediately without commercial interference.

Regulatory Recordkeeping Mandates (10 CFR 34 Subpart E)

Federal and Agreement State regulations impose strict retention schedules for all records generated during radiographic operations under 10 CFR 34 Subpart E (§§ 34.61–34.89). Radiography inspectors prioritize records verification during compliance audits. Records are bifurcated into 3-year retention items and lifetime / license-termination items:

3-Year Retention Schedule (10 CFR 34 Subpart E)

The licensee must maintain the following operational records for a minimum of 3 years after generation:

• Survey Meter Calibrations (10 CFR 34.65): Calibration certificates showing the multi-point calibration required by 34.25(b)(2) — approximately 1/3 and 2/3 of full scale on each linear scale — demonstrating accuracy within $\pm 20%$ of the calibration source, performed at intervals not to exceed 6 months.
• Quarterly Physical Source Inventories (10 CFR 34.69): Records of the 34.29 quarterly inventory, listing the date, the individual conducting it, the radionuclide, activity or DU mass, location, and the manufacturer, model, and serial number of each sealed source and device.
• Sealed Source Leak Tests (10 CFR 34.67): 6-month leak test results, stated in becquerels (microcuries), confirming removable activity below $185\text{ Bq}$ ($0.005\ \mu\text{Ci}$). If a wipe test reveals $\ge 0.005\ \mu\text{Ci}$, 10 CFR 34.27(d) requires the equipment to be withdrawn from use immediately, decontaminated and repaired or disposed of, and a report filed within 5 days.
• Quarterly Equipment Inspection and Maintenance Logs (10 CFR 34.31(b)(1); records under 34.73): Inspection and routine maintenance at intervals not to exceed 3 months for exposure devices, source changers, associated equipment, containers, and survey instruments.
• Daily Operational Inspection Checklists (10 CFR 34.73): Field logs documenting daily pre-operational checks of cameras, pigtail connectors, guide tubes, drive cables, survey meters, and pocket dosimeters.
• Utilization Logs (10 CFR 34.71): Daily logs tracking camera serial number, isotope, activity, date removed/returned from storage, radiographer signature, and exact job site location.
• Training, Refresher, and Job-Performance Records (10 CFR 34.79): Certification documents, written and practical examination records, annual refresher training topics and attendees, and the semi-annual job-performance inspections of each radiographer and assistant.
• Alarm System and Entrance Control Test Records (10 CFR 34.75): Results of the daily alarm tests and monthly entrance control device tests required at permanent installations by 10 CFR 34.33(b).
• Annual Radiation Protection Program Reviews (10 CFR 20.2102): Formal RSO audits assessing ALARA performance, dose trends, and regulatory compliance.
• Reciprocity Documentation (10 CFR 150.20): Filed copies of NRC Form 241 and fee receipts.

Notices, Instructions, and Reports to Workers (10 CFR Part 19)

The IRRSP body of knowledge lists "notices, reports, and records" as a regulatory topic, and the notices half lives in 10 CFR Part 19, not Part 34:

• 10 CFR 19.11 — Posting of notices to workers. The licensee must post current copies of the regulations in Parts 19 and 20, the operating license and license conditions or documents incorporated by reference, the operating procedures applicable to licensed activities, and any notice of violation or order — or, in each case, post NRC Form 3, "Notice to Employees," with a statement of where those documents may be examined. Documents must be posted within 2 working days of receipt and remain posted for 5 working days or until corrective action is completed, whichever is later. Where posting in a particular place is impractical, the licensee may post at a location where workers passing will observe it.
• 10 CFR 19.12 — Instruction to workers. Workers likely to receive an occupational dose in excess of 100 mrem in a year must be instructed in the storage, transfer, and use of radioactive material; the health protection problems associated with exposure; precautions and procedures to minimize exposure; the applicable provisions of NRC regulations and the license; their responsibility to report unsafe conditions; the appropriate response to warnings; and their radiation exposure reports rights under 10 CFR 19.13.
• 10 CFR 19.13 — Notifications and reports to individuals. Workers must receive their own dose data, including the annual report of their dose and a report on termination of employment.
• 10 CFR 19.20 — Employee protection. Prohibits discrimination against a worker for raising a safety concern — the legal foundation of a radiography crew's stop-work authority.

---

Lifetime / License-Termination Retention Schedule

Specific foundational records must be preserved permanently until the NRC or Agreement State formally terminates the facility license:

• Personnel Dosimetry Records (10 CFR 20.2106): Cumulative lifetime occupational radiation exposure histories documented on Form NRC-5 or vendor dosimetry reports (film badges, TLDs, OSLDs), including annual TEDE, shallow dose equivalent (SDE), lens dose equivalent (LDE), and investigations of abnormal exposures.
• Radiation Protection Program Foundational Documents (10 CFR 20.2102): The original written radiation protection manual, operating procedures, and all documented historical amendments.
• Decommissioning and Restricted Area Records (10 CFR 30.35(g)): Historical radiological surveys of storage vaults, restricted area boundary releases, and records of any leaking sources or site contamination.
