Toxic Exposure
Atomic Veterans & Radiation Exposure
Radiation-exposed veterans under §3.309(d), §3.311, and the PACT Act cleanup missions
Veterans exposed to ionizing radiation — nuclear test participants, Hiroshima/Nagasaki occupation forces, and cleanup crews — have three distinct legal routes to service connection, and most claims fail because only one was argued.
Three Routes, Not One
Radiation claims are unusual because the regulations create three independent paths, and a claim that only argues one is a claim that has thrown away two chances. Most denials we review argued the presumptive route, lost, and stopped.
Route 1 — Presumptive under §3.309(d)
If you are a “radiation-exposed veteran” who participated in a radiation-risk activity and you have one of the listed diseases, service connection is presumed. No dose estimate, no nexus opinion required.
Route 2 — Radiogenic disease under §3.311
For a broader list of radiogenic diseases, the VA must obtain a dose estimate and refer the claim to the Under Secretary for Benefits for an opinion on whether it is at least as likely as not that the exposure caused the disease. This is not a presumption — it is a mandatory development procedure the VA often skips.
Route 3 — Direct under §3.303(d)
Any disease, presumptive or not, can be service-connected directly with evidence of exposure and a competent medical nexus. *Combee v. Brown* confirms the presumptions do not foreclose this route.
Who Is a Radiation-Exposed Veteran
Participation in an atmospheric nuclear test — Operations CROSSROADS, SANDSTONE, GREENHOUSE, IVY, CASTLE, TEAPOT, REDWING, HARDTACK, DOMINIC, and others
Occupation forces at Hiroshima or Nagasaki between Aug 6, 1945 and July 1, 1946
Prisoner of war in Japan with opportunity for comparable exposure
Service at gaseous diffusion plants at Paducah, Portsmouth, or Oak Ridge (K-25) for at least 250 days
Service at Amchitka Island, Alaska before Jan 1, 1974 during underground nuclear testing
Cleanup of Enewetak Atoll (1977–1980), Palomares, Spain (1966–1967), or Thule Air Base, Greenland (1968) — added by the PACT Act
Presumptive Diseases Under §3.309(d)
Leukemia (other than chronic lymphocytic leukemia)
Cancer of the thyroid, breast, pharynx, esophagus, stomach, small intestine, pancreas
Multiple myeloma; lymphomas other than Hodgkin’s disease
Cancer of the bile ducts, gall bladder, liver (unless cirrhosis or hepatitis B is indicated)
Cancer of the salivary gland, urinary tract, bone, brain, colon, lung, ovary
Bronchiolo-alveolar carcinoma
The §3.311 Development the VA Skips
Section 3.311 is a procedural mandate, not an option. When a veteran claims a radiogenic disease and alleges radiation exposure during service, the VA is required to obtain a dose assessment — from the Defense Threat Reduction Agency for test participants, or from service records for occupational exposure — and then refer the claim for an advisory medical opinion considering the dose, the latency period, the veteran’s age at exposure, and other risk factors.
When a decision denies a radiogenic disease claim without any dose estimate in the file and without a §3.311 referral, the VA has failed its own duty to assist. That is a procedural defect, and procedural defects are precisely what Higher-Level Review exists to fix.
The Advocate’s Take
If your denial letter never mentions a dose estimate, the VA almost certainly never performed the §3.311 development it was required to perform. That is a winnable duty-to-assist error, not a medical loss.
Evidence That Wins Radiation Claims
DD-1141 (Record of Occupational Exposure to Ionizing Radiation), if one exists
DD-214 and orders establishing test participation or occupation-force service
DTRA dose reconstruction, or a request that one be obtained
Unit assignment records for cleanup missions at Enewetak, Palomares, or Thule
Pathology reports establishing the specific diagnosis and date
Statements describing your proximity, duties, and any protective measures — or their absence
Where the VA Gets This Wrong
Denials routinely conclude “dose too low to have caused the disease” using a reconstructed estimate that the veteran never had the chance to rebut. Under §3.311(c) the dose is one factor among several — latency, age at exposure, and other risk factors must also be weighed, and often were not.
Building a Atomic Veterans & Radiation Exposure Claim That Wins
Every claim stands on three legs. Knock one out and the claim falls over, no matter how bad your symptoms are. Before you file, look at your file and find all three.
A current diagnosis
A doctor has to say you have it, now, in writing. Not "reports symptoms of" — a diagnosis. Without this leg, nothing else in the file matters.
A link to your service
An event, an injury, an exposure, or an already service-connected condition. Service records, unit records, buddy statements, and your own account all count as evidence.
A nexus that ties the two together
A medical opinion stating it is at least as likely as not that your service caused or aggravated the condition. That phrase is a legal standard: 50 percent or better. It is the leg most denials break.
Document the problem before you file
• Keep a dated symptom log for at least 30 days. Frequency, severity, and what it stopped you from doing.
• Get statements from people who see it — a spouse, a coworker, a battle buddy. Lay evidence is legal evidence.
• Pull your private treatment records. The VA only has to help; it does not have to go find everything.
• Write down what you have stopped doing. Lost work, lost sleep, lost activities. That is what impairment looks like on paper.
Your Rights in This Process
It costs nothing to file
Filing a VA claim is free. Accredited representatives may only charge for work on an appeal after an initial decision, and those fees are capped by 38 CFR §14.636.
The VA has a Duty to Assist you
Under 38 CFR §3.159 the VA must help you get the evidence it needs, and it must tell you what is missing before it denies you for missing it.
You can ask for a different examiner
You may request a trauma-informed clinician, or a clinician of a specific gender, for a C&P examination. Ask before the exam is scheduled.
You can claim every condition you have
There is no limit and no penalty. Primary conditions, secondary conditions, and conditions made worse by service all get filed.
You can appeal and be re-evaluated
A denial is not the end. You may submit new evidence, request a higher-level review, appeal to the Board, and ask for re-evaluation when your condition worsens.
You must be considered for TDIU
If your service-connected conditions keep you from holding substantially gainful employment, you may be paid at the 100 percent rate without a 100 percent rating.
When You Are Ready to File
Talk to an accredited representative before you file. It costs nothing to ask, and the order you file in changes what the VA is allowed to award you. Albert L. Thombs Jr. is VA-Accredited Claims Agent #45147.
The application itself
This is the form that opens a disability compensation claim. List every condition you are claiming, and name the secondary conditions explicitly.
Release for private records
Authorises the VA to request records from your private doctors. Without it, treatment outside the VA may never reach your file.
Lay or buddy statement
The official form for your own statement and for statements from people who witnessed the event or the change in you.
