Sure, that is SOP. That said even in my high school some medical rafioactive waste went missing. Admittedly that was a long time ago.
But a friend of mine who worked as a mechanic at a nuke plant always brought home tyvek suits and stuff.
What about dental and other low level but measurable nuke waste?
It’s basically harmless but measurable and therefore scary to people who don’t understand radiation.
Well, x-rays and gamma rays don’t activate material. It either has to be contaminated by material being embedded in it, (any most sources are well sealed, preventing release) or activated by neutrons. Most medical procedure materials are fast decaying.
I had an Iron-55 source that had decayed to the point where a source disposal company said I could feed it to my dog, but regulations required all manner of paperwork to get it off the books and “properly” disposed of.
