To amend title 38, United States Code, to establish a presumption that certain veterans were exposed to radiation and other toxins at the Nevada Test and Training Range for purposes of the treatment of certain disabilities under the laws administered by the Secretary of Veterans Affairs, and for other purposes.

Summary

Treats certain onsite work and service at locations within the Nevada Test and Training Range (NTTR) between January 1, 1972 and January 1, 2005 as radiation-risk or toxic-exposure events, creating presumptions that make it easier for affected veterans to obtain VA disability benefits. It defines which NTTR locations are covered (including Indian Springs Auxiliary Airfield) and explicitly excludes Nellis Air Force Base and Creech Air Force Base. The bill also adds a presumption that lipomas and tumor-related conditions are service-connected for veterans covered by the new NTTR exposure presumption.

• Treats onsite participation at certain NTTR locations (1972–2005) as radiation-risk activities for VA purposes.
• Defines "covered location at the Nevada Test and Training Range" to include NTTR sites and Indian Springs Auxiliary Airfield, and to exclude Nellis AFB and Creech AFB.
• Creates a presumption of toxic exposure for service at covered NTTR locations (including airspace) during 1972–2005.
• Establishes that lipomas and tumor-related conditions are presumed service-connected for veterans covered by the new NTTR presumption.
• Reduces veterans' burden to prove exposure or service connection for the newly covered conditions, shifting proof requirements to the VA.
• Does not include new appropriations or explicit implementation funding in the text.
• Applies only to service within a specified geographic area and time window; service outside those bounds is not covered.
• May increase VA claims workload and benefit outlays due to additional presumptive claims.
