NBR ARO Exam study plan

NBR ARO Exam · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Regulatory Framework and Statutory Requirements

  • Map the full regulatory hierarchy from statute to binding license condition, and state in writing where each layer's authority comes from.

  • Build a citation index of the core provisions governing byproduct material possession, use, and transfer, keyed to section numbers.

  • Distinguish the obligations that attach to a general license versus a specific license, and list three activities permitted under each.

  • Explain how rulemaking, orders, and license conditions interact when they conflict, using a worked example you construct yourself.

Your checkpoint

A one-page regulatory hierarchy diagram plus a 15-entry citation index with section numbers and one-sentence summaries.

Week 2

Regulatory Framework and Statutory Requirements

  • Summarize the statutory basis for exemptions, general licenses, and the boundaries of agency jurisdiction over different radiation sources.

  • Compare the roles of the governing statute, agency regulations, and guidance documents in setting enforceable requirements.

  • Trace how a statutory amendment propagates into license conditions and inspection criteria.

  • Identify the provisions that impose duties on the licensee's responsible officers rather than on the institution.

Your checkpoint

A 500-word written analysis of how one regulatory change would flow from statute to license condition, with citations.

Week 3

Licensing, Registration, and Application Procedures

  • Outline the complete lifecycle of a specific license from pre-application through termination, naming each required filing.

  • Draft the component sections of an application: facility description, equipment inventory, personnel qualifications, and radiation safety program.

  • Determine when an amendment is required versus when a notification or letter suffices.

  • Identify the criteria reviewers apply when judging financial assurance and decommissioning funding.

Your checkpoint

A complete mock license application package with all required sections and a cover index.

Week 4

Licensing, Registration, and Application Procedures & Radiation Safety and Protection Principles

  • Apply the time-distance-shielding relationship to calculate dose rates at specified distances from a source.

  • Convert between activity units, exposure, absorbed dose, and dose equivalent, showing each step.

  • State the occupational and public dose limits and the constraints that apply to declared pregnant workers and minors.

  • Explain ALARA as an operational program requirement rather than a slogan, listing the mechanisms that implement it.

Your checkpoint

A worked problem set of 10 dose and shielding calculations with full unit conversions and a summary sheet of all applicable limits.

Week 5

Radiation Safety and Protection Principles & Facility Operations, Equipment, and Security

  • Describe the design features of a controlled area that satisfy access control, posting, and surveillance requirements.

  • Specify the survey instruments needed for a given source inventory, including calibration frequency and range adequacy.

  • Sequence the security controls for source storage, inventory reconciliation, and response to a missing-source alarm.

  • Explain how to establish and document a radiation area boundary using measured survey data.

Your checkpoint

A facility safety plan for a hypothetical site covering posting, access, instrument calibration schedule, and security procedures.

Week 6

Inspection, Enforcement, and Compliance

  • Anticipate the records and observations an inspector will request during an announced inspection, and assemble a pre-inspection binder outline.

  • Classify violations by severity and predict the enforcement response for each class.

  • Draft a corrective action plan that addresses root cause, interim controls, and verification of effectiveness.

  • Distinguish an immediately reportable event from one handled through routine reporting channels.

Your checkpoint

A mock inspection response packet containing a pre-inspection checklist, a sample corrective action plan, and a reporting decision tree.

Week 7

Recordkeeping, Reporting, and Documentation & Professional Ethics and Administrative Responsibilities

  • Build a retention schedule listing each required record, its custodian, retention period, and retrieval method.

  • Write the reporting calendar for routine submissions with lead times and responsible parties.

  • Apply the ethical duties of accuracy, candor, and non-retaliation to three constructed dilemma scenarios.

  • Explain the licensee's duty to report known or suspected violations and the protections for raising concerns.

Your checkpoint

A records retention and reporting calendar matrix plus three written ethics case analyses with a defensible course of action for each.

Week 8

Regulatory Framework and Statutory Requirements & Radiation Safety and Protection Principles & Inspection, Enforcement, and Compliance

  • Rehearse the highest-yield regulatory and safety facts through spaced retrieval until recall is consistent.

  • Complete two timed practice sets and categorize every missed item by domain and error type.

  • Rework each missed item into a corrected one-line rule you can restate from memory.

  • Verify weak-domain coverage by re-testing only the items missed in earlier weeks.

Your checkpoint

A scored practice exam log with error analysis by domain and a one-page final review sheet of corrected rules.

Milestones

Week 2: Can state the regulatory hierarchy from memory and cite the controlling provision for three common licensing scenarios without notes.

Week 4: Scores at least 80 percent on a self-made 20-item quiz covering domains 1 through 3, with all dose calculations correct to the stated unit.

Week 6: Produces a complete mock inspection packet and correctly classifies eight of ten constructed scenarios as reportable or routine.

Week 8: Scores at least 85 percent on two timed practice sets and shows a declining error count in the two weakest domains.
