Abstract
A method for production of carrier free {sup 123} I with high radionuclidic purity in which the processing is done remotely was developed at Instituto de Engenharia Nuclear in Rio de Janeiro. The {sup 123} I is produced in the decay of {sup 123} Xe which is obtained through the reaction {sup 122} Te ({sup 3} He, 2 n) {sup 123} Xe with 30 MeV {sup 3} He beams of IEN`s variable energy cyclotron. The irradiated natural Te O{sub 2} target is heated in a furnace at 675{sup 0} C and the diffused out {sup 123} Xe is adsorbed in a copper trap maintained at -196{sup 0} C. The {sup 123} Xe is allowed to decay during 6.3 hours and the {sup 123} I produced washed out of the trap with a 0.1 N solution of NaOH. All the process is remotely controlled by using electric and pneumatic systems as well as manipulators and tongs. The quality control was achieved by atomic absorption and gamma-ray spectroscopy.
