Pretreated silica sand labeling using varying concentrations of tin(II) fluoride and chloride as reducing agents and different times labeling was performed in order to develop a methodology for labeling silica sand with .sup.99mTc for using as solid radiotracer. Influence of different sand pretreatment parameters on the sorption yield (R.sub.ret%) was statistically evaluated. The effectiveness of the methods used to reduce pertechnetate (.sup.99mTcO.sub.4.sup.-) by ascending paper chromatography was confirmed. Results show relatively high values of .sup.99mTc sorption yields on silica sand. It was possible to establish a methodology for obtaining solid .sup.99mTc labeled radiotracers in support of silica sand.
