> I guess the worry here is that the other person is unqualified to handle and dispose of the device and cause bodily injury to self? Yes. Or even more precisely the worry is that someone who maybe took it doesn't even recognise that they have to safely handle it. Imagine that you have a very sharp sword. If you do the wrong thing with it can maim you. Further imagine that nobody has a "sword sense". They just can't see the edge. So people just take it and you only realise that they come in contact with a sword when they report to a hospital with multiple deep cuts. What is worse is that they might go to a hospital report that they have deep cuts and nobody thinks that they had a sword. Because swords are very rare and people get similar symptoms for other non-sword reasons. And the hospital itself only starts to suspect that they have a sword incident when multiple people starts to report with injuries which can be caused by a sword. And then they have to send out specialist with a sword-finding equipment who are trained to handle the sword safely without themselves being able to see the edge. Radioactive sources are like that sword nobody can see the edge of. There are all kind of procedures, and if you follow them they can be handled safely. But if you don't even know that what you have has an "edge" you are not just unqualified to do those procedures, but you also don't know that you should do anything special. Here is a list of "orphan source incidents" [1]. Which is basically radioactive safety people speak for "the radioactive thing went on a walkabout to places it shouldn't have". Some of the tales are beyond terrible. That being said I have no clue how "hot" this thing is. If you believe other commenters probably not very? 1: https://en.wikipedia.org/wiki/List_of_orphan_source_incidents https://en.wikipedia.org/wiki/List_of_orphan_source_incident...
