Abstract : An electron linear accelerator was used to produce gaseous oxygen-15 by bremsstrahlung irradiation of hydrogen peroxide-water solutions. With helium as a sweep gas, it was possible to achieve oxygen-15 activities of 24 mCi per liter of gas. Carbon-11, the only detectable radioactive contaminant, constituted less than 0.2% of the activity when 30-MeV electrons were used. Transfer of oxygen-15 to blood by a simple bubbling technique resulted in blood activities of about 85 micro Ci/cc of blood. (Author)
