I took a minute to quickly check which sample would have the most activity, assuming 100g, low-enriched (5%) samples, and negligible activity from the other sample constituents. Radium is top by a factor of 10,000, which seems about right considering my personal experience with it.
“considering my personal experience with it” What the fuck does this imply
It implies I have personal experience with handling radium samples, which I have. That saucy little thot can make the geiger counter crackle through a lead plate more than americium can through air
