Radiation Presumptive Conditions And Service Rules

This group contains the 21 disease categories and radiation-risk activities in 38 CFR 3.309(d). It does not treat all radiation contact as presumptive exposure. The separate dose-development procedure for radiogenic diseases in 38 CFR 3.311 requires individual consideration and is not listed as automatic service connection.

Scope And Legal Distinctions

• This is a public compensation reference, not a personal eligibility or medical determination. Every row retains source-specific service, timing and activity limits.
• Location labels sometimes group places that share the same rule. Different legal pathways remain separate even when a condition or location appears more than once.
• Broad statutory cancer categories are not expanded into every pathology synonym. VA says its cancer examples are non-exhaustive. The nine named rare respiratory cancers and selected later named additions are listed separately.
• Affected C-123 unit dates and specialty codes remain in the linked VA unit table. The overall 1962-1986 span is not a blanket service window. Special Exposure Cohort designations also require the specific site, duties and duration; they are not all enumerated here.
• The changelog contains documented milestones verified in this research pass, not every historical amendment to every presumption. No later addition is asserted merely because it appeared in a proposal or regulatory agenda.
• Other presumptive programs, birth-defect benefits, health-care enrollment rules, individual exposure determinations and radiation dose-development claims are outside this table.

Current Gulf War Statute And Older Regulation Text

38 U.S.C. 1117 now permits a qualifying chronic disability to manifest to any degree at any time and adds six countries. Older limits remain printed in 38 CFR 3.317(a). The chronic-illness rows follow the current statute and VA guidance; the separate infectious-disease manifestation rules remain explicit.

Herbicide Dates And Current Statutory Conditions

The Korean DMZ window uses September 1, 1967, and the Guam/American Samoa window ends July 31, 1980. These follow current statutes and the VA disability page. Older or inconsistent summaries were not used to narrow these dates. Statutory conditions absent from the older regulatory list are still included.

Grouped Cancer Names Do Not Broaden Anatomical Restrictions

The anatomical category and primary diagnosis matter. A named subtype may also appear under a broader category; these rows do not establish separate payments for the same disability. Radiation and herbicide exclusions remain attached to their particular pathways.
