The Department of Defense has recognized more than half a million veterans who may have been exposed to radiation while the nation built and tested atomic weapons — atmospheric shots in Nevada and the Pacific, occupation duty in Hiroshima and Nagasaki, and decades of Cold War cleanup work. Most were never told what dose they absorbed. Many were ordered never to discuss the tests, and the records that would prove participation stayed classified for years. That silence still costs families money today, because nuclear weapons testing veterans compensation turns on documents most veterans do not know exist. This 2026 guide explains who qualifies, which agency pays, what evidence moves a claim, and where every rule can be confirmed.
Key Takeaways
- Confirm whether the service period fits a VA "radiation-risk activity," which triggers presumed exposure with no proof of dose required.
- Request a participation and dose record from the Defense Threat Reduction Agency's Nuclear Test Personnel Review program before filing.
- Match the diagnosis against both VA lists — the presumptive cancers under 38 CFR 3.309(d) and the case-by-case diseases under 38 CFR 3.311.
- Compare the VA disability route with the separate Department of Justice RECA program, which pays on different rules and a different clock.
- File an Intent to File first so the effective date is locked while records are still being gathered.
- Track the December 31, 2027 RECA filing deadline, which does not move when a VA claim is still pending.

Who Qualifies: Radiation-Risk Activity and Presumed Exposure
Veterans who worked around nuclear weapons rarely received a straight answer about what they absorbed, and that uncertainty stops claims before they start. VA removes part of the guesswork with a category called a radiation-risk activity. When service fits one of those categories, VA presumes exposure occurred and the veteran never has to prove a dose number.
VA Public Health lists the recognized activities. They include participation in atmospheric nuclear weapons tests conducted primarily in Nevada and the Pacific Ocean between 1945 and 1962; occupation duty in Hiroshima or Nagasaki, Japan between August 6, 1945 and July 1, 1946; internment as a prisoner of war in Japan near those cities during World War II; underground testing at Amchitka Island, Alaska before January 1, 1974; service at the Nevada Test Site for at least 250 days from January 1, 1963 through December 31, 1992; and at least 250 days of service before February 1, 1992 at the gaseous diffusion plants in Paducah, Kentucky, Portsmouth, Ohio, or the K-25 area at Oak Ridge, Tennessee.
Presumed exposure is only half the test. VA.gov states that the veteran must also have an illness on the recognized list, or one a physician says may be caused by radiation, and that the illness must have appeared within the timeframe attached to that list. Exposure by itself is not a disability. A claim is always filed for a diagnosed condition, never for the assignment that caused it.
Service outside those categories is not a dead end. Weapons handling, calibration and measurement sources, radioactive material, and occupational monitoring can all support a claim. Those cases simply travel a second route that requires a dose assessment instead of a presumption, and that route is covered later in this guide.
The Three Cleanup Missions the PACT Act Added
The PACT Act added three response and cleanup efforts to the presumptive list, and VA.gov publishes the exact windows: cleanup of Enewetak Atoll from January 1, 1977 through December 31, 1980; cleanup after the B-52 crash off Palomares, Spain from January 17, 1966 through March 31, 1967; and the response to the B-52 fire near Thule Air Base, Greenland from January 21, 1968 through September 25, 1968. Veterans denied before those windows existed have a reason to look again.
Evidence: Participation, Dose, and Diagnosis
The hardest part of a nuclear testing claim is rarely the medicine. It is proving the veteran was there. Personnel records from that era often name a unit and a duty station without ever naming a test series, and many participants were told to say nothing. VA still needs two things: service records showing participation in a recognized radiation-risk activity, and medical records showing the diagnosis.
Three record sets carry most of these claims. The Official Military Personnel File establishes assignments and dates. Service treatment records establish what was reported at the time. The Defense Department dose record establishes participation in a specific event. When the personnel file is thin, deck logs, muster rolls, travel orders, and unit histories fill the gap, and those archival records often survive when an individual file did not.
Lay and buddy statements matter more here than in an ordinary claim. A shipmate who describes where the unit staged, what the working party did, and how decontamination was handled is giving competent evidence of observable facts. Such statements cannot establish a dose figure. Their job is to place the veteran at the event so the agencies can find the dose.
Getting a Dose Record from the Nuclear Test Personnel Review Program
The Nuclear Test Personnel Review program, run by the Defense Threat Reduction Agency, confirms veteran participation in U.S. nuclear tests from 1945 to 1992 and in the occupation forces of Hiroshima and Nagasaki. DTRA states that for a confirmed participant it can provide either an actual or an estimated radiation dose, and that VA and the Department of Justice request that information during claim reviews as required. Veterans and survivors may contact NTPR directly at 800-462-3683 instead of waiting for an agency to ask on their behalf.
Matching the Diagnosis to the Right List
VA maintains two separate lists. The presumptive list under 38 CFR 3.309(d) covers leukemia other than chronic lymphocytic leukemia, multiple myeloma, lymphomas other than Hodgkin's disease, and primary cancers of the bile ducts, bone, brain, breast, colon, esophagus, gall bladder, liver, lung, pancreas, pharynx, ovary, salivary gland, small intestine, stomach, thyroid, and urinary tract. The second list, applied case by case under 38 CFR 3.311, covers all cancers, non-malignant thyroid nodular disease, parathyroid adenoma, posterior subcapsular cataracts, tumors of the brain and central nervous system, and other diseases supported by medical or scientific evidence.
Filing Strategy: VA Compensation, RECA, and Claim Type
Two different federal programs pay veterans of the nuclear weapons program, and confusing them costs people money. They have different agencies, different proof standards, and different deadlines. Filing with one does not file with the other.
VA disability compensation is administered by the Department of Veterans Affairs. It pays monthly, it is tax free, it requires a rating tied to a diagnosed condition, and it has no filing deadline. Under Public Law 104-262, veterans exposed during a radiation-risk activity are placed in Priority Group 6 for care of the related condition, without regard to age, service-connected status, or ability to pay, and with no copayment for that care.
The Radiation Exposure Compensation Act is administered by the Department of Justice, not VA. DOJ states that RECA was reauthorized under the One Big Beautiful Bill Act, Public Law 119-21, enacted July 4, 2025, and that it is a non-adversarial program which does not require claimants to prove causation. Onsite Participants qualify by showing presence above or within a government installation during a test involving the atmospheric detonation of a nuclear device conducted by the United States before January 1, 1963, plus a diagnosis of a compensable disease. Wartime detonations at Hiroshima and Nagasaki are excluded from that definition. A RECA payment to an Onsite Participant is offset by amounts already received from VA for the same illness, and all RECA claims must be filed by December 31, 2027. DOJ is working to issue revised regulations during 2026 and continues to apply 28 C.F.R. Part 79 in the meantime.
Standard Claim or Fully Developed Claim
A Fully Developed Claim is the faster lane, but it assumes every record is already in hand. Nuclear testing claims usually depend on federal records held by another agency, and the duty to assist is what compels VA to go get them. When a dose request is still outstanding at DTRA, or archival deck logs have been requested and not received, the standard claim route generally protects the veteran better than a Fully Developed Claim filed early and decided on an incomplete file.
Filing Step by Step
Paperwork order matters here, because the first form filed usually sets the money date. The sequence below keeps the effective date protected while the slower records are still moving.
- File an Intent to File. Submit VA Form 21-0966 to open a one-year window and preserve the effective date before any evidence is collected.
- Pull the participation record. Request the Official Military Personnel File and service treatment records, and order archival deck logs or unit histories for the dates in question.
- Request the dose record. Contact the Nuclear Test Personnel Review program at 800-462-3683 for confirmation of participation and an actual or estimated dose.
- Document the diagnosis. Collect pathology reports, treatment records, and the date of diagnosis for each claimed condition, from VA or private providers.
- Submit VA Form 21-526EZ. Name every diagnosed condition separately, attach the records, and file online or with an accredited representative.
Protecting the Effective Date with an Intent to File
The Intent to File is the single highest-value form in this process and takes minutes to submit. Once accepted, the claim that follows within one year is generally treated as filed on the earlier date. For a veteran chasing archival records from the 1950s, that window is often the difference between a full award and months of lost retroactive pay. The form protects the date regardless of how the claim is eventually decided.
What to Send and What to Skip
Send the diagnosis, the participation evidence, and any dose documentation already received. Send lay statements that describe duties and locations. Skip general articles about radiation risk, internet printouts about other veterans' cases, and anything that argues the science rather than documenting this veteran. A separate RECA claim, if one applies, is filed with the Department of Justice through its own claim portal and does not travel with the VA package.
After Filing: Exams, Reviews, and Decision Reviews
Waiting is the part veterans dread, and the timelines have moved. VA reported in June 2026 that the average time to complete a decision was 78.6 days at the end of May 2026, compared with 141.5 days on January 20, 2025, and that claims-processing accuracy is above 94 percent. Those are averages across all claims; a file waiting on a federal dose record from another agency can run longer.
Most claimants will be scheduled for a VA examination. The examiner's role is to document the current severity of the diagnosed condition and answer the medical questions VA asks. An examiner cannot confirm a decades-old radiation dose and should not be expected to. Attending the appointment and describing the condition at its worst is what the exam is for.
When the Claim Goes to the Under Secretary for Benefits
Claims that fall outside the presumptive list follow 38 CFR 3.311. VA first obtains a dose assessment. Where the estimate is reported as a range, the regulation directs that exposure at the highest level of the range be presumed — a detail that works in the veteran's favor and is worth knowing. If the dose assessment supports exposure and the disease is radiogenic within the prescribed timeframe, the claim is referred to the Under Secretary for Benefits, who determines the likelihood that service exposure caused the disease.
The Three Decision Review Lanes
A denial is not the end. A Supplemental Claim adds new and relevant evidence, such as a dose record or archival log that arrived late. A Higher-Level Review asks a senior reviewer to find an error on the evidence already in the file, with no new evidence allowed. An appeal to the Board of Veterans' Appeals puts the case before a Veterans Law Judge. VA.gov specifically directs veterans denied before a condition became presumptive to file a Supplemental Claim so the case is reviewed again under the current rules.
Take the Next Step
Nuclear testing claims fail on missing records far more often than on weak medicine. Before filing, it helps to know which records are missing, which list the diagnosis belongs on, and whether a second federal program applies. The free VA Claim Readiness Test at avoyvet.com walks through those questions in a few minutes and returns a plain-language readiness picture, along with educational guidance from AVOY Veteran Navigator AI on evidence, deadlines, and next steps. Veterans, spouses, and surviving family members can use it free, as often as needed, while the claim is built.
Frequently Asked Questions
Does the PACT Act cover Enewetak, Palomares, and Thule cleanup veterans?
Yes. VA.gov lists three response and cleanup efforts added as presumptive-exposure locations: cleanup of Enewetak Atoll from January 1, 1977 through December 31, 1980, cleanup after the B-52 crash off Palomares, Spain from January 17, 1966 through March 31, 1967, and the response to the B-52 fire near Thule Air Base, Greenland from January 21, 1968 through September 25, 1968. Service inside one of those windows means VA presumes radiation exposure. The veteran still must show a diagnosed illness from the recognized list, appearing within the applicable timeframe. Veterans who were denied for one of these missions before the windows were added should file a Supplemental Claim rather than assume the old denial still controls the outcome.
Can a veteran receive both VA compensation and a RECA payment?
They are separate programs and both can be pursued, but they interact. VA disability compensation is a monthly, tax-free payment administered by VA and tied to a rating. RECA is a one-time lump-sum payment administered by the Department of Justice under rules that do not require proving causation. DOJ states that a RECA payment to an Onsite Participant is offset by amounts already received from VA for the same illness, so the second payment is reduced rather than duplicated. Filing one claim does not file the other; each has its own form, its own agency, and its own evidence. Current amounts and offset rules should be confirmed directly with the Department of Justice RECA program.
What if the discharge papers never mention a nuclear test?
That is the normal situation, not a disqualifier. Separation documents almost never name a test series, and many participants were instructed not to discuss the mission. The Nuclear Test Personnel Review program exists precisely to resolve this: it confirms participation in U.S. nuclear tests from 1945 to 1992 and in the Hiroshima and Nagasaki occupation forces, and provides an actual or estimated dose for confirmed participants. Archival deck logs, muster rolls, travel orders, and unit histories can also place a veteran at an event when the personnel file is silent. A buddy statement from someone in the same working party adds observable detail that records sometimes lack entirely.
Is there a deadline to file under RECA?
Yes, and it is firm. The Department of Justice states that all RECA claims must be filed by December 31, 2027. That deadline runs on its own clock and does not pause because a VA claim is still pending, because records are still being requested, or because an appeal is underway. DOJ also notes that it is working to issue revised regulations during 2026 and will continue applying the existing regulations at 28 C.F.R. Part 79 until those are published. Claims can be submitted electronically through the RECA claim portal or by mail with original or certified supporting documents. The program can be reached toll-free at 800-729-7327 for application questions.
What does the Ionizing Radiation Registry exam do, and does it start a claim?
The Ionizing Radiation Registry health exam is a free VA screening offered to eligible veterans to alert them to possible long-term health problems related to ionizing radiation exposure. Eligibility includes on-site participation in a test involving atmospheric detonation of a nuclear device, occupation duty in Hiroshima or Nagasaki between August 6, 1945 and July 1, 1946, internment as a prisoner of war in Japan during World War II, and several service-specific categories. The registry exam is a health service, not a disability claim. It does not establish service connection, does not set an effective date, and does not substitute for filing. The exam findings can, however, become useful medical evidence later.
What happens if the diagnosed cancer is not on the presumptive list?
The claim moves to the case-by-case route under 38 CFR 3.311 instead of being denied outright. VA obtains a dose assessment, and where the estimate comes back as a range, the regulation directs that exposure at the highest level of that range be presumed. If the assessment supports exposure and the disease qualifies as radiogenic within the prescribed timeframe, the claim goes to the Under Secretary for Benefits, who weighs the likelihood that service exposure caused it. VA's case-by-case list includes all cancers, non-malignant thyroid nodular disease, parathyroid adenoma, posterior subcapsular cataracts, and tumors of the brain and central nervous system, plus other diseases supported by medical or scientific evidence.
Can a surviving spouse or child file after the veteran dies?
Survivors have pathways under both programs. On the VA side, a surviving spouse, dependent child, or dependent parent may pursue survivor benefits where the service-connected condition contributed to the death, and a claim pending at the time of death may be continued by an eligible survivor. On the DOJ side, the Department of Justice states that when a qualifying individual has died, survivors may apply for equal shares of the single RECA payment. Families should preserve the veteran's military records, medical records, and death certificate rather than discarding them once an estate is settled, because those documents are exactly what both programs ask for.
