I just skimmed it, because much of what was there was familiar, although there were some nuggets about which I was unaware, for example that the ionization source at airport MS's is a radioisotope.

If Tc was not mentioned, it should have been. Tc^99m is one of the most important medical isotopes there is, generally milked from Mo⁹⁹ decay.

(It's nice to have the superscripts back at DU, but it appears that the HTML codes for greek letters are missing.)
