NNSA’s Office of Radiological Security and Medstar Georgetown University Hospital worked together to remove a cesium-137 blood irradiator on Aug. 7 and replace it with an X-ray irradiator at the hospital’s Washington, D.C., facility.

NNSA and the hospital partnered late last year as part of the 2020 Cities Initiative and the Cesium Irradiator Replacement Project. The project works with volunteer sites throughout the nation to replace their high-activity radioactive sources with non-radioisotopic alternatives. This removal marks the 50th replacement of an irradiator through the program.

Georgetown University Hospital benefits from the alternative technology by working with a more efficient and convenient technology to process blood products.

The removal advances NNSA’s mission to reduce the global reliance on high-activity radioactive sources through the adoption and development of non-radioisotopic alternative technologies where technically, operationally, and economically feasible.
