Ahem, Blame the Daughter!

TO THE EDITOR:

As an ardent amateur physicist I find the use of terms such as germanium attenuation correction in the Journal discordant (1). After all, this is The Journal of Nuclear Medicine, and a nuclide’s mass number is best specified. Germanium in this case is number 68, but alas, the authors seem not even to realize that the attenuation source is actually ⁶⁸Ga, the positron-emitting daughter of ⁶⁸Ge, a β− emitting nuclide.
