Radiation Exposure — VA Disability Rating & Claim Guide

Peer-Reviewed Medical Evidence

Real, verified studies from PubMed/NIH that support a Radiation Exposure claim. Bring these citations to your accredited VSO or C&P exam — they help show your condition is recognized in the medical literature and, where noted, linked to other service-connected conditions.

• Mortality among U.S. military participants at eight aboveground nuclear weapons test seriesDirect

  International Journal of Radiation Biology, 2022 · PMID 32602389

  Finding: In a cohort of 114,270 male 'atomic veterans' who participated in U.S. atmospheric nuclear weapons tests and were followed up to 65 years, the all-cancer standardized mortality ratio (SMR) was significantly elevated after 50 years (SMR 1.10), with the highest SMRs for mesothelioma (1.56, linked to shipboard asbestos) and prostate cancer (1.13). Internal dose-response analyses (mean red bone marrow dose only 6 mGy) found no statistically significant increasing trend with radiation dose.

  Why it helps: This is the largest direct study of U.S. atomic veterans and documents elevated long-term cancer mortality in this group; it supports an association between participation in nuclear test programs and excess cancer (notably mesothelioma and prostate cancer), while showing exposures were generally low-dose.

• Epidemiological studies of UK test veterans: II. Mortality and cancer incidenceDirect

  Journal of Radiological Protection, 2004 · PMID 15511015

  Finding: Across analyses of UK participants in atmospheric nuclear weapons tests compared with a matched control group, overall mortality and cancer incidence were similar to controls, but there was some evidence of a raised risk of leukemia other than chronic lymphatic leukemia, particularly in the early years after the tests. The authors concluded that a small absolute radiation-related leukemia risk from test participation could not be ruled out.

  Why it helps: Supports an association between nuclear weapons test participation and leukemia (excluding CLL), reinforcing recognition of leukemia among radiation-exposed test veterans.

• Ionising radiation and risk of death from leukaemia and lymphoma in radiation-monitored workers (INWORKS): an international cohort studyDirect

  The Lancet Haematology, 2015 · PMID 26436129

  Finding: Among 308,297 radiation-monitored workers (including U.S. Department of Defense and Energy workers) followed for 8.22 million person-years at very low dose rates (mean 1.1 mGy/year), the excess relative risk of leukemia mortality excluding CLL was 2.96 per Gy (90% CI 1.17-5.21), driven especially by chronic myeloid leukemia (ERR 10.45 per Gy, 90% CI 4.48-19.65).

  Why it helps: Provides strong evidence that even protracted low-dose ionizing radiation exposure is associated with increased leukemia risk, relevant to veterans with documented occupational radiation exposure.

• Risk of cancer associated with low-dose radiation exposure: comparison of results between the INWORKS nuclear workers study and the A-bomb survivors studyDirect

  Radiation and Environmental Biophysics, 2021 · PMID 33479781

  Finding: In a harmonized comparison of 45,625 atomic bomb survivors and 259,350 nuclear workers, the excess relative rate (ERR) for solid cancer was 0.28 per Gy (90% CI 0.18-0.38) in survivors and 0.29 per Gy (90% CI 0.07-0.53) in workers, with leukemia ERR per Gy of 2.75 and 3.15 respectively and no significant heterogeneity between the two populations.

  Why it helps: Shows consistent dose-response for both solid cancer and leukemia across acute (bomb survivor) and protracted low-dose (worker) exposures, supporting an association between cumulative ionizing radiation dose and cancer in radiation-exposed populations.

• Ionizing radiation and leukemia mortality among Japanese Atomic Bomb Survivors, 1950-2000Direct

  Radiation Research, 2009 · PMID 19708786

  Finding: Among Japanese atomic bomb survivors in the Life Span Study with 310 leukemia deaths over 1950-2000, estimated bone marrow dose was significantly associated with leukemia mortality, with about 103 of the 310 leukemia deaths attributable to radiation; acute myeloid leukemia showed the strongest dose-response, and the effect persisted decades after exposure.

  Why it helps: Foundational evidence establishing a dose-related association between ionizing radiation exposure and leukemia (especially AML) that endures for decades, underpinning recognition of leukemia as radiation-related.

• Surveillance of Depleted Uranium-exposed Gulf War Veterans: More Evidence for Bone EffectsDirect

  Health Physics, 2021 · PMID 33867437

  Finding: In 36 Gulf War veterans with depleted uranium (DU) 'friendly-fire' shrapnel followed since 1994, those with retained DU fragments had elevated urinary uranium, and the high-DU subgroup showed a statistically significant increase in the bone-resorption marker N-telopeptide and a significant decrease in bone mineral density compared with the low-DU subgroup.

  Why it helps: Supports an association between retained depleted uranium exposure in veterans and adverse bone effects (reduced bone mineral density), a biologically plausible uranium target-organ effect detected across consecutive surveillance visits.
