More cool stuff in my shop packing.. What goes well with lasers? A box of radioactive stuff!

A made a short video testing out a few of the samples:

It’s fun to collect different sources. Those radioactive vacuum tubes are pretty zesty, and getting harder to find. At 810uSv/hr at a few inches, that is a pretty good radiator given the metal enclosure and the primary alpha decay of Radium226->Po218 (and the alpha is probably blocked by the case).

Background radiation here in Portland is around 0.16 uSv/hr, so that is 5000x background levels. Probably not something you want to keep on your nightstand.
