Estimates of absorbed radiation dose and qualitative assessments of image resolution were compared for pure /sup 131/I and for /sup 123/I produced by the /sup 122/Te(d,n), /sup 124/Te(p,2n), and /sup 127/I(p,5n)/sup 123/Xe reactions. A substantial reduction in radiation dose is indicated when /sup 123/I replaces /sup 131/I, in spite of the radiocontaminants typically present 30 to 35 hr after the production of /sup 123/I by any of these methods. Only a marginal further reduction in radiation dose was noted with use of the most ''pure'' /sup 123/I as opposed to the least ''pure'' /sup 123/I. Comparable scintillation camera resolution was obtained for all /sup 123/I preparations at 30 to 35 hr after bombardment when the medium-energy and pinhole collimators were used. However, the radiocontaminants in the /sup 123/I produced from tellurium affected image resolution when the low-energy collimator was used.
