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.

Creates a presumption that active military, naval, air, or space service at specified locations within the Nevada Test and Training Range between January 1, 1972 and December 31, 2004 qualifies as toxic exposure for purposes of VA benefits. It defines which sites at the Range are “covered” (including Indian Springs Auxiliary Airfield) and excludes certain bases (Nellis AFB and Creech AFB). The bill also adds lipomas and related tumor conditions to the list of presumptive conditions for veterans who meet that service-location test.
