A historical perspective on the specific activity of radiopharmaceuticals: what have we learned in the 35 years of the ISRC?
20 January 2012
Suzanne E. Lapi, Michael J. Welch
Abstract: Specific activity (SA), defined as the amount of radioactivity per unit mass of a compound, is arguably one of the most important parameters in radiopharmaceutical development, particularly ...
