Scientists at Pacific Northwest National Laboratory have developed an innovative portable blood irradiator that provides mobile, extra-corporeal irradiation of blood in vivo. The blood irradiator uses thulium and vitreous carbon to destroy circulating lymphocyctes, nearly colorless cells that function in the development of immunity. A portable blood irradiator has the potential to dramatically enhance the success rates for treating diseases such as leukemia, lymphomas, and early rejection of bone-marrow transplants.

Background: Development of a fully portable blood irradiator began at Pacific Northwest in the early 1970s, when there were no mechanisms to treat blood diseases and help suppress rejection of transplanted organs or tissues. The technology was transferred to the Fred Hutchinson Cancer Research Center (Seattle, Washington) in 1991. Manufacture and delivery of the irradiators and the development of safer, more effective protocols for their use is occurring through Pacific Northwest's first Cooperative Research and Development Agreement with Fred Hutchinson Cancer Research Center. All this led to significant benefits to the medical community, including a safer, more effective treatment for leukemia patients.
