Effect of milking efficiency on 99Tc content of 99mTc derived from 99mTc generators
Abstract:
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.
