Generally, … Witryna22 lip 2024 · The radioactivity of impurity radionuclides is normally 3–9 orders of magnitude lower than 99m Tc in the 99m Tc eluate. It is impossible to directly measure these impurity radionuclides using radiometric methods, removal of most of 99m Tc is needed before measurement of other gamma emitters.
