USTUR logo

After 9 years of decreasing and flat funding, our annual funding was increased by 20%. In January, the USTUR submitted a 5-year grant renewal proposal for the period of April 1, 2017 to March 31, 2022. A budget of $5,500,000 was requested by the USTUR and approved by the Department of Energy, Office of Health and Safety (AU-10). Funding at this level will allow the USTUR to keep up the the increasing costs associated with autopsies and radiochemically analyzing tissue samples. It will also increase the USTUR’s visibility by allowing faculty members to present the Registries’ research at scientific meetings.
