Description

An on-line facility for the production of 123I by spallation of elemental caesium by 482 MeV protons has been in operation at a TRIUMF beam dump for about two years. Radioxenon from the target is efficiently trapped on alumina which is subsequently used to remove the 121Te decay product. The yield is 100 mCi/h from a 20 g/cm2 target at 10 μA. Impurities are 125I <2% and 121Te <0.2% at 27 h after end of production. The 123I consists mainly of iodide along with significant iodate impurity. The product is used extensively in Canadian clinics for thyroid analyses and labelling radiopharmaceuticals. (auth)
