The U.S. Nuclear Regulatory Commission has proposed one of the most consequential changes to federal radiation protection regulations in decades.
On July 1, 2026, the NRC announced a proposed rule that would replace the longstanding regulatory principle of keeping occupational and public radiation exposure as low as reasonably achievable, commonly known as ALARA. In its place, the NRC is proposing a more objective, risk-informed, and performance-based radiation protection framework.
Importantly, the proposal would not change the NRC’s existing occupational or public dose limits. It would change how licensees are expected to manage exposures below those limits and how compliance is demonstrated.
For NRC and Agreement State licensees, this is not merely a change in terminology. Depending on the final rule, it could eventually affect radiation protection procedures, ALARA reviews, dose investigations, program audits, license commitments, medical-use practices, and regulatory inspections.
What is the NRC proposing?
Under current NRC regulations, licensees must generally use procedures and engineering controls based on sound radiation protection principles to achieve occupational and public doses that are ALARA. This expectation often requires organizations to evaluate whether additional reductions in exposure are reasonable, even when measured doses are already well below regulatory limits.
The NRC is now proposing to replace ALARA as a separate regulatory expectation with requirements centered on:
- Compliance with established dose limits
- Required radiation protection precautions
- A graded approach based on actual risk and operating conditions
- More flexible methods for evaluating worker and public dose
- Expanded options for managing occupational exposure
The NRC stated that ALARA can create additional cost, administrative complexity, and regulatory ambiguity without producing a measurable safety benefit in situations where exposures are already very low. According to the agency, the objective is to improve regulatory clarity while retaining the existing dose limits and overall level of protection.
Does this mean radiation dose limits are increasing?
No.
The NRC’s announcement specifically states that the existing dose limits for workers and members of the public would remain unchanged. The proposal focuses on the additional optimization activities licensees may currently perform after demonstrating compliance with those limits.
That distinction is important. The proposed rule does not mean that licensees could disregard radiation protection controls until a dose limit is reached. Requirements governing access control, surveys, monitoring, respiratory protection, contamination control, postings, training, recordkeeping, and other protective measures would continue to apply unless specifically revised.
The practical question is whether a licensee would continue to be required to pursue progressively lower doses when established precautions have been implemented and regulatory limits are already being met.
What would replace ALARA?
The NRC describes the proposed framework as risk-informed, performance-based, and graded.
A graded approach generally means that the extent of dose-management controls would be proportionate to the radiological risk. A facility with the potential for significant worker exposure would continue to require robust engineering controls, monitoring, procedures, and oversight. An operation producing only minimal and well-characterized exposures might be permitted to use a more streamlined program.
The proposal would also provide licensees with greater flexibility to use modern dose-evaluation methods rather than relying exclusively on prescriptive approaches developed decades ago.
The details will matter. The final regulatory language and associated guidance will determine:
- Which precautions are mandatory for different activities
- When additional dose-management measures are expected
- How licensees must document their decision-making
- What constitutes adequate performance
- How inspectors will evaluate compliance
- Whether existing licensing guidance and enforcement policies will be revised
Until those details are finalized, licensees should not assume that the proposal eliminates the need for a formal radiation protection program or documented dose-management decisions.
Which NRC licensees could be affected?
The NRC identifies numerous affected sections of Title 10 of the Code of Federal Regulations, including Parts 19, 20, 34, 35, 40, 50, 61, 71, 72, and 150. The proposal therefore has potential implications for a broad range of regulated activities, including:
- Industrial radiography
- Medical use of radioactive material
- Nuclear power and non-power reactors
- Uranium recovery and source-material operations
- Radioactive waste management
- Transportation of radioactive material
- Independent spent-fuel storage
- NRC and Agreement State radiation protection programs
The NRC currently identifies the rulemaking as “Reforming and Modernizing the NRC’s Radiation Protection Framework,” Docket ID NRC-2025-1140 and RIN 3150-AL47. Federal Register publication is presently scheduled for July 15, 2026, although the NRC notes that its rulemaking schedule is subject to change.
What could this mean for existing radiation safety programs?
The proposal could eventually allow some licensees to simplify portions of their radiation protection programs. However, the extent of any relief will depend on the final rule, corresponding guidance, license conditions, and Agreement State implementation.
Potentially affected program elements include:
ALARA committees and periodic reviews
Some organizations maintain formal ALARA committees, quarterly exposure reviews, investigation levels, and recurring optimization analyses. The final rule may reduce or modify some of these activities, particularly where exposures are consistently low and operations are well controlled.
However, an ALARA committee or review process may still be required by a facility’s license, internal procedures, accreditation commitments, or state regulations. A federal rule change would not automatically remove those obligations.
Investigation levels
Many programs establish administrative investigation levels substantially below the occupational dose limits. These levels are valuable for identifying unusual trends, control failures, or changes in work practices.
Even if no longer required under an ALARA framework, well-designed investigation levels may remain an effective management tool. Licensees will need to distinguish between administrative controls that provide meaningful operational value and controls maintained solely because of outdated regulatory expectations.
Engineering and administrative controls
The proposal should not be interpreted as permission to replace effective engineering controls with less protective work practices. Shielding, containment, remote handling, ventilation, access restrictions, work planning, and time-distance-shielding principles will remain fundamental components of radiation protection.
The likely change is that licensees may have greater discretion to determine when additional controls are justified after compliance and required precautions have already been established.
Documentation
A more performance-based framework may reduce prescriptive documentation in some areas, but it may also place greater importance on documenting the technical basis for a licensee’s decisions.
For example, a licensee may need to explain why its controls are appropriate for the source term, exposure pathways, operating conditions, and reasonably foreseeable events. Flexibility generally works best when the underlying technical evaluation is clear and defensible.
How could the proposal affect medical licensees?
The NRC also proposes allowing caregivers of patients receiving treatments involving radioactive materials to voluntarily receive higher doses under appropriate conditions.
This provision could provide additional flexibility when family members or other caregivers assist patients following radiopharmaceutical therapy. The objective is to support patient care while maintaining informed consent and appropriate radiation protection measures.
Medical licensees should watch closely for proposed requirements involving:
- Caregiver eligibility
- Voluntary participation
- Dose constraints or limits
- Written instructions
- Documentation of informed consent
- Prospective dose estimates
- Patient-release instructions
- Exposure to minors or pregnant individuals
The final wording will determine whether this change materially affects current patient-release and caregiver-management practices.
What does this mean for Agreement State licensees?
The proposal includes 10 CFR Part 150 and could eventually influence the National Materials Program. However, NRC publication of a final rule would not necessarily create immediate, identical changes in every Agreement State.
Depending on the compatibility category assigned to individual provisions, Agreement States may need to adopt corresponding requirements. Implementation dates, terminology, guidance, and enforcement approaches could vary during the transition.
Organizations operating in multiple states should therefore avoid applying a single assumption across all locations. Each applicable NRC or Agreement State license will need to be evaluated separately.
Should licensees change their ALARA programs now?
No.
This is a proposed rule, not a final rule. Existing regulations, license conditions, procedures, and commitments remain in effect. Licensees should continue implementing their approved radiation protection and ALARA programs until applicable requirements are formally changed.
Prematurely removing ALARA reviews, modifying investigation levels, or discontinuing documented controls could create inspection or enforcement concerns under the regulations currently in effect.
What should licensees do now?
Organizations do not need to redesign their radiation protection programs immediately, but they should begin evaluating how the proposal could affect them.
A practical review should include:
- Identify where ALARA appears in the program. Review licenses, applications, procedures, radiation protection manuals, training materials, audit checklists, and contractual commitments.
- Separate regulatory requirements from internal best practices. Some controls may remain valuable even if they are no longer expressly required.
- Review dose history and operating risk. Licensees with consistently low exposures may have different concerns from organizations conducting high-dose, variable, or complex work.
- Evaluate Agreement State requirements. Determine which program elements arise from NRC regulations, state regulations, license conditions, or commitments made in the license application.
- Review the proposed language carefully. The NRC press release describes the policy direction, but the regulatory text and statements of consideration will control how the proposal would operate.
- Consider submitting comments. Organizations should identify provisions that are unclear, difficult to implement, unnecessarily prescriptive, or likely to create unintended consequences.
The public-comment period
The NRC plans to accept public comments for 45 days following publication of the proposed rule in the Federal Register and intends to hold a public meeting during the comment period.
Comments are most effective when they provide more than general support or opposition. Useful submissions typically identify:
- The specific proposed provision
- The operational or regulatory concern
- Supporting dose, cost, or performance information
- The likely effect on safety and compliance
- Recommended alternative language
Licensees should also consider whether their industry associations are preparing coordinated comments.
The bottom line
The NRC’s proposal represents a fundamental shift in radiation protection philosophy—from an open-ended expectation to minimize exposure whenever reasonably achievable toward a more objective system based on dose limits, required precautions, risk, and operational performance.
The proposal may ultimately reduce unnecessary administrative burden, particularly for well-controlled activities involving very low exposures. At the same time, it will require careful implementation to ensure that greater flexibility does not create inconsistent expectations among licensees, inspectors, and Agreement States.
For now, the most important points are:
The current dose limits are not being increased. Existing radiation protection requirements remain in force. ALARA programs should not be changed until the rulemaking is complete and the applicable regulatory authority has implemented the final requirements.
