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.

H.R. 1400 would amend veterans' benefits law to create a legal presumption that certain veterans were exposed to radiation and other toxins while serving at the Nevada Test and Training Range. Under current law, veterans seeking disability compensation for radiation-related illnesses must prove their exposure occurred. This bill would shift that burden by presuming exposure happened for eligible veterans, making it easier for them to qualify for VA treatment and compensation without having to demonstrate exposure individually.

If enacted, the bill could expand access to Veterans Affairs healthcare and disability benefits for veterans who served at the Nevada Test and Training Range and developed certain illnesses potentially linked to radiation exposure. The practical effect would be that affected veterans would no longer need to gather extensive evidence of their exposure to receive treatment and benefits for qualifying conditions. The bill is currently under consideration in the House Subcommittee on Disability Assistance and Memorial Affairs and has not yet been voted on by the full House.
