A Lecture on Radioisotopes Geared to teach High School Teachers. (Original Post) NNadir Oct 2023 OP
Skimmed the slides. First I've ever heard of "betavoltaics"! eppur_se_muova Oct 2023 #1

Second the sub/superscripts -- but even copy-and-paste Greek characters don't work ... eppur_se_muova Oct 2023 #3
I think it's a bug that EarlG and Elad will fix. It seems to apply to all symbol HTML codes. NNadir Oct 2023 #4

I didn't see Tc mentioned anywhere, which I thought was peculiar. Did I miss it?

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. Tc99m 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.)

I put a note about it in the "Announcements" forum.
