Abstract

99Mo−99mTc generators were prepared starting from irradiated molybdenum metal instead of MoO3 in order to use reactor irradiation space more economically. The adsorption of molybdenum as sodium molybdate on different kinds of alumina was investigated. The effect of the pH of the column and the aqueous phase concentration of molybdenum were studied and related to the elution yield of99mTc. A study of the radiation damage effect indicated that generators having a high elution efficiency of 90% could be prepared in the 100–600 mCi range. The losses of99Mo were minimized to 10−5-10−4% and those of alumina to 2–5 μg/ml eluate.
