History of the USTUR
National Radiobiology Archives
The U.S. National Radiobiology Archives (NRA) program was transferred from Pacific Northwest National Laboratory (PNNL) to the USTUR in 1996. The USTUR was the custodian of these materials until 2010, when the NRA was transferred to Northwestern University, Chicago, IL. The NRA houses a valuable collection of animal tissue specimens and data from government sponsored radiobiology life-span studies performed at various national laboratories and universities since the 1940’s.
