Ionizing Radiation: The Presumptive Path and the Radiogenic Path Are Different

The presumptive track is 38 U.S.C. 1112(c), carried into regulation at 38 CFR 3.309(d). A veteran who participated in one of the listed radiation-risk activities and has one of 21 listed diseases gets service connection presumed. No dose estimate. No medical opinion connecting the disease to service. The statutory list and the regulatory list are identical in content and in order, which is unusual and worth noting given how far the herbicide statute and regulation have drifted apart.

The other track is 38 CFR 3.311, which uses the term radiogenic disease. Meeting its conditions does not grant anything. It opens a dose assessment, after which the claim is decided as ordinary direct service connection on all the evidence. Section 3.311(f) says so directly, and 3.311(g) preserves the willful misconduct and supervening cause defenses.

Confusing the two is the standard error in this category, and it usually runs in one direction: a veteran reads that their cancer is on a radiation list, assumes the claim is automatic, and is surprised by a dose assessment and a request for records.

38 CFR 3.309(d)(3)(ii) lists eight. Onsite participation in a test involving the atmospheric detonation of a nuclear device. The occupation of Hiroshima or Nagasaki by United States forces between August 6, 1945 and July 1, 1946. Internment as a prisoner of war in Japan during World War II, or active duty in Japan immediately after, where the internment created a comparable opportunity for exposure. Service in a capacity that would qualify a Department of Energy employee for the Special Exposure Cohort.

Service at a gaseous diffusion plant at Paducah, Kentucky, Portsmouth, Ohio, or the area identified as K25 at Oak Ridge, Tennessee, for at least 250 days before February 1, 1992, with dosimetry badge monitoring or a position of comparable exposure. The same subparagraph covers service on Amchitka Island, Alaska before January 1, 1974 for anyone present during the Long Shot, Milrow or Cannikin underground tests. The 250 days are cumulative, and the monitoring condition is a second requirement on top of them.

Then the three cohorts the PACT Act added: cleanup of Enewetak Atoll from January 1, 1977 through December 31, 1980; the Palomares, Spain response effort from January 17, 1966 through March 31, 1967; and the Thule, Greenland response effort from January 21, 1968 through September 25, 1968.

The Palomares dates get garbled often enough to state plainly. The period starts in 1966, the year of the collision, and ends in 1967. A start date of 1967 would put it a year after the accident.

Leukemia other than chronic lymphocytic leukemia, and cancers of the thyroid, breast, pharynx, esophagus, stomach, small intestine, pancreas, bile ducts, gall bladder, salivary gland, urinary tract, bone, brain, colon, lung and ovary. Plus multiple myeloma, lymphomas except Hodgkin's disease, primary liver cancer except where cirrhosis or hepatitis B is indicated, and bronchiolo-alveolar carcinoma.

The list is closed and every item on it is a malignancy. There is no catch-all. If the diagnosis is not on that list, the 3.309(d) presumption does not reach it, whatever the exposure was.

Prostate cancer, skin cancer, kidney cancer, urinary bladder cancer, cancer of the rectum, posterior subcapsular cataracts, non-malignant thyroid nodular disease and parathyroid adenoma all appear in the 24-item radiogenic list at 38 CFR 3.311(b)(2) and none of them appears in the 21-item presumptive list. The radiogenic list also ends with any other cancer, at (b)(2)(xxiv), which is why it can reach diagnoses nobody enumerated.

Prostate cancer is the case that comes up most. A veteran with prostate cancer and documented radiation exposure has no presumption available and does have a radiogenic disease claim, which is a real route with a real procedure attached to it.

The traffic runs the other way too. Cancer of the pharynx, small intestine, bile ducts and gall bladder, and bronchiolo-alveolar carcinoma are presumptive under 3.309(d) and are not named in the radiogenic list, though the catch-all would still reach them.

38 CFR 3.311 is also not limited to the eight cohorts. Its trigger at (b)(1)(i) includes other activities as claimed, which is what makes it available to nuclear-powered ship and submarine crews, radiology and dental x-ray technicians, weapons handlers and others who were never part of an atmospheric test.

For atmospheric testing and Hiroshima or Nagasaki occupation claims, VA requests dose information from the Department of Defense, which runs the Nuclear Test Personnel Review program through the Defense Threat Reduction Agency. Veterans do not have to contact the Department of Defense themselves before applying. For any other claimed exposure, VA works from available records including DD Form 1141, the Record of Occupational Exposure to Ionizing Radiation, and the Under Secretary for Health prepares an estimate.

Two provisions inside 3.311 tilt in the claimant's favor and are easy to miss. Where a dose is reported as a range, 3.311(a)(1) presumes exposure at the highest level of that range. And 3.311(a)(4) concedes presence at the site where service records neither establish nor rule it out, so independent proof of presence is not required when the records support the claimed exposure.

If a claimant submits a credible dose estimate that materially differs from the service department's, an independent estimate is obtained from an expert. Material difference is ordinarily where one estimate is at least double the other. The file then goes to the Under Secretary for Benefits and, where causation cannot be settled, to an outside consultant selected from a list recommended by the Director of the National Cancer Institute, who reports whether causation is likely, unlikely or approximately as likely as not.

Latency gates apply under 3.311(b)(5). Bone cancer must become manifest within 30 years after exposure. Leukemia may become manifest at any time. Posterior subcapsular cataracts must become manifest six months or more after exposure. Everything else on the radiogenic list must become manifest five years or more after exposure.

VA's ionizing radiation eligibility page does not enumerate the 21 presumptive diseases on the page. It splits eligibility into an illness on VA's list of illnesses believed to be caused by radiation and an illness that doctors say may be caused by radiation, which are the two tracks, but it does not name or explain the second one. The regulation link it provides points to 3.311, the non-presumptive path.

A reader who follows that link lands on the dose assessment procedure and reads a longer disease list that includes prostate and skin cancer. It is easy to come away believing those are presumptive. They are not.

There is also a genuine inconsistency inside the regulations themselves. 38 CFR 3.311(b)(1)(i) describes the Hiroshima and Nagasaki occupation as running from September 1945 until July 1946. 38 U.S.C. 1112(c)(3)(B) and 38 CFR 3.309(d)(3)(ii)(B) both use August 6, 1945 as the start. The presumptive track uses the earlier date.

One VA path worth knowing is which URL is live. The ionizing radiation page sits at /ionizing-radiation/; the shorter /radiation/ path returns a 404, as does the old public health disease list page.

It added the three response and cleanup cohorts, Enewetak Atoll, Palomares and Thule, to 38 U.S.C. 1112(c)(3)(B). Unlike the herbicide side, where five PACT Act locations still have no regulatory text at all, the radiation regulation was updated to match. 38 CFR 3.309(d)(3)(ii)(F), (G) and (H) carry the same three cohorts with the same dates.

For anyone on Enewetak between 1977 and 1980, at Palomares between January 1966 and March 1967, or at Thule between January and September 1968, the presumptive framework applies with no dose assessment and no medical opinion required. The 21-disease list still governs what it covers.

One offset is written into the statute. Under 38 U.S.C. 1112(c)(4), a radiation-exposed veteran who receives a payment under the Radiation Exposure Compensation Act of 1990 does not lose VA compensation because of it, but the amount of that payment is deducted from the VA compensation.

A free accredited VSO can file either type of radiation claim and does not charge for it. That matters more than usual here, because picking the wrong section to file under is the common failure and it costs time rather than money.
