A Lecture on Radioisotopes Geared to teach High School Teachers.

A nice little lecture to educate our educators on radioisotopes, provided by the ANS.

1. Skimmed the slides. First I've ever heard of "betavoltaics"!

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

2. To be honest, I didn't watch the whole thing myself.

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.)

3. Second the sub/superscripts -- but even copy-and-paste Greek characters don't work ...

They do show up in the preview, but not the final post!

4. I think it's a bug that EarlG and Elad will fix. It seems to apply to all symbol HTML codes.

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