“Atomic veteran” is a regulatory term. It covers a defined set of Cold War-era service experiences involving ionizing radiation. Where that service is present and a listed radiogenic disease later develops, statute instructs VA to presume the disease is service-connected[src], implemented at 38 CFR § 3.309(d)[src].
Who qualifies as an “atomic veteran”
§ 3.309(d)(3) defines a “radiation-exposed veteran” as someone who participated in a “radiation-risk activity” during active service. The regulation lists those activities.
- Onsite participation in a U.S. atmospheric nuclear test between 1945 and 1962 (Trinity and operations including Crossroads, Sandstone, Greenhouse, Upshot-Knothole, Castle, Redwing, Plumbbob, Hardtack, and Dominic).
- Occupation service in Hiroshima or Nagasaki between August 6, 1945 and July 1, 1946.
- Internment as a prisoner of war of Japan that resulted in presence within 75 kilometers of Hiroshima or Nagasaki during the period above, to an extent that VA finds exposure comparable to the occupation forces.
- Service before February 1, 1992at the gaseous diffusion plants at Paducah, Kentucky; Portsmouth, Ohio; or the K-25 area at Oak Ridge, Tennessee, for at least 250 days and meeting the regulation’s other conditions.
- Onsite participation at Amchitka Island, Alaska before January 1, 1974, during the Long Shot, Milrow, or Cannikin underground nuclear tests (January 1965 – October 1971).
- Service at other listed nuclear weapons production facilities as described in § 3.309(d).
- Certain post-1962 atmospheric test cleanup personnel covered by the regulation’s narrow follow-on list, including Enewetak Atoll cleanup operations.
Proof of participation is typically drawn from unit records, ship deck logs, Defense Threat Reduction Agency (DTRA) confirmation letters, DD-214 and DD-215 entries, and National Personnel Records Center (NPRC) files. The full regulatory text at § 3.309(d) controls; read it (or have a representative read it) before concluding you are or are not covered.
Presumptive conditions (38 CFR § 3.309(d))
For a radiation-exposed veteran, the following diseases are presumed service-connected if they become manifest to any degree, at any time after service.
Radiogenic cancers
- Leukemia (other than chronic lymphocytic leukemia)
- Multiple myeloma
- Lymphomas (except Hodgkin’s disease)
- Thyroid cancer
- Breast cancer
- Brain cancer (primary cancer of the brain)
- Cancer of the pharynx
- Esophageal cancer
- Stomach cancer
- Small intestine cancer
- Pancreatic cancer
- Cancer of the bile ducts
- Cancer of the gall bladder
- Primary liver cancer (other than one due to cirrhosis or hepatitis B)
- Colon cancer
- Lung cancer (bronchio-alveolar carcinoma and other primary lung cancers)
- Bone cancer
- Cancer of the salivary gland
- Cancer of the urinary tract (kidney, renal pelvis, ureter, urinary bladder, urethra)
- Ovarian cancer
Non-malignant conditions
- Non-malignant thyroid nodular disease
- Posterior subcapsular cataracts
The regulation as currently codified controls; conditions have been added over time. Confirm the current text at eCFR § 3.309(d) before assuming a diagnosis is off-list.
How presumptive service connection works
“Presumptive” means VA presumes the causal link between service and disease — the veteran does not have to produce a medical nexus letter. That is a real reduction in evidentiary burden, but it is not automatic. A presumptive claim still needs three things.
- Qualifying service. Evidence that the veteran participated in a radiation-risk activity as defined in § 3.309(d)(3). DTRA confirmation of participation, NPRC records, ship deck logs, and unit morning reports are the usual sources.
- A current diagnosis of one of the listed radiogenic diseases, supported by medical records (pathology, imaging, specialist notes).
- A filed claim. VA will not apply the presumption on its own; the veteran (or a survivor for DIC) must file and cite the exposure.
Where all three are present, VA may grant without an additional nexus opinion, which can shorten processing for straightforward cases.
Non-presumptive radiation claims (38 CFR § 3.311)
Not every radiation-related claim fits the § 3.309(d) presumption. 38 CFR § 3.311[src] creates a separate evidence-development path — for example, a listed disease in a veteran whose service is not on the § 3.309(d) list, or a disease § 3.311 recognizes as potentially radiogenic but § 3.309(d) does not cover.
The § 3.311 process is more involved. It typically requires VA to obtain a radiation dose estimate from DTRA or the VA Under Secretary for Health, then refer the case for medical-opinion review considering dose, latency period, and specific disease. It is not a presumption; it is a structured way to develop the record so a rater can decide whether service connection is at least as likely as not. These claims benefit from a representative who has worked them before.
RECA — the DOJ-administered compensation program
The Radiation Exposure Compensation Act (RECA) is a separate federal program administered by the Department of Justice, not VA[src]. RECA pays lump-sum awards — typically in the $50,000 to $100,000 range depending on claimant category — to three broad groups.
- Onsite participants at atmospheric nuclear tests who later develop a listed cancer.
- “Downwinders” who lived for defined periods in specific counties of Nevada, Utah, and Arizona, and later develop a listed cancer.
- Uranium miners, millers, and ore transporters who worked in the industry during defined periods and developed specified diseases.
RECA is independent of VA compensation. A veteran may be eligible for both at once; receiving one does not automatically bar the other, though the interaction is worth walking through with a representative. RECA has been subject to repeated reauthorization debates; confirm current eligibility, covered counties, diseases, and filing deadlines at the DOJ RECA page before relying on older guides.
How to file a VA atomic-veteran claim
The mechanics match any other VA disability claim — what changes is the evidence packet. Our how-to-file guide covers filing paths and the Intent to File that protects your effective date. For an atomic-veteran claim specifically, useful documents include:
- DD-214 and any DD-215 showing dates, unit, and any exposure-related annotations
- Evidence of qualifying service— unit records, ship deck logs, morning reports, orders, or NPRC file excerpts placing the veteran at a listed test, occupation zone, or facility
- DTRA correspondence confirming participation in a specific test series or operation, if available
- Current medical records diagnosing the claimed condition (pathology, imaging, specialist notes)
- Lay statements from the veteran and, where available, fellow service members describing the exposure circumstances
File on VA Form 21-526EZ and cite 38 CFR § 3.309(d) (or § 3.311 if going the non-presumptive route). A surviving spouse or dependent pursuing Dependency and Indemnity Compensation should cite the same authorities.
Where to get help
Atomic-veteran claims lean on historical records that most general representatives rarely handle. A few resources worth knowing:
- National Association of Atomic Veterans (NAAV). Advocacy group with institutional memory on test-series participation and DTRA requests. They can sometimes point to records a general search would miss.
- CVSO or VSO with atomic-veteran experience. Rare at the county level; national service organizations (DAV, VFW, American Legion, and others) sometimes have staff who have worked these cases. Ask directly whether the office has filed § 3.309(d) or § 3.311 claims.
- VA Regional Office radiation coordinator. Each regional office has a point of contact for ionizing-radiation claims who can help route evidence development.
- DOJ RECA claims staff. For the separate RECA program only, not VA claims.
A conservative word on posture
Atomic-veteran claims involve specialized records (DTRA, the former Defense Nuclear Agency, NPRC), decades-old unit and ship logs, and a compensation landscape — especially RECA — that has been in legislative flux. This page is a starting point. Specific cases benefit from an experienced representative and from direct contact with advocacy groups who have seen the records before. If your service falls within the activities above, the presumption exists because Congress and VA concluded the link was real; it is worth pursuing.
