The video posted by Telix is not very recent for my last straw.

Since that video was posted, there have been some recent developments regarding Cu isotopes which are making them easier to obtain.

Again my interest in this stock is from the fact that current isotopes require a nuclear reactor so they are difficult to produce. Apparently Cu isotopes don't require a special reactor. But I will need to do more research.

Note my chemistry experience only extends to Year 12 high school. I only understand enough about half lives etc...
