As I recall, the tests Gordon was doing in Black Mesa involved a mass spectrometer. In real life, mass spec has little to nothing to do with "half-life," which is a term used to describe the time is takes radioactive material to lose half its radioactivity. The best way to measure half-life is to use a sodium iodide or similar detector and do a simple count test, not use a mass spec. In fact, for longer lived isotopes, I think it would be highly inefficient to make that measuremnent with a mass spec., as it would take a very long time for a measureable different in mass to develop.
I like to think the title, "half life," has to do with the fact that we only know part of Gordon's life. That is, we know what he was like just before the accident at BM and after the accident, but we don't really know anything about his relationship with the G-man. Ergo, we know, "half" of gordon's "life."
