A bill to provide that service connection for disabilities arising from exposure to ionizing radiation or dioxin may be established by direct evidence.

Amends the Veterans' Dioxin and Radiation Exposure Compensation Standards Act to ensure that the regulations provided under such Act are not construed to prohibit a veteran from establishing service connection for a disease or disability that the veteran claims to be the result of exposure to ionizing radiation or dioxin during a specified period of service, notwithstanding that such regulations do not specify that the disease or disability is radiogenic or associated with dioxin.
