Description

A decontamination study of iodine-131 contamination by Ce (IV)/HNO3 was carried out using orthogonal tests for radioactive contamination of metal surfaces. The effects of nitric acid concentration, Ce (IV) concentration, temperature, and decontamination time on the decontamination factors of brass and aluminum were obtained. The maximum value of decontamination factor was 5.80 for brass: temperature was approximately equal to Ce (IV) concentration than decontamination time than nitric acid concentration, and the maximum value of decontamination factor was 319.49 for aluminum: Ce (IV) concentration than decontamination time than nitric acid concentration than temperature.
