Effect of milking efficiency on 99Tc content of 99mTc derived from 99mTc generators.
Calculation was made of the effect of milking efficiency on the 99Tc content of 99mTc derived from 99mTc-generators. Reduced milking efficiency was shown to lead to an increase in the 99Tc/99mTc ratio. Levels of 99Tc were determined in samples from both column and solvent extraction generators using a HPLC procedure. It is recommended that producers of 99mTc from solvent extraction generators should ensure that complete generator milking is performed daily.
