Yes i did. But since I can not always tell the diffrence when I see the 2 typers of equippment and the possible outcome can be a disaster I feel a warning is ok.
If you do not know what metall you get from the machine you do not know the machine you scrapping. The shape of the scrap could very well be from a container. If heavy it migth be a shield alloy.
Personally i would not put my fingers on those type of equippment that can potentially be so harmfull, if mistaken. But leave them for proffessionals knowing their trade. In this case safty equipment is missing as well good knowledge about what he is scrapping. I have seen so much crazy things laying around at old dumpsites, scrapyards and former industries that i am extremly careful when looking around. I have found shells, cyanide and a lot other scary things.
The problem is if Joe now starts to look for this type of scrap and get hold of an old machine a 94 year old Doctor, with altsheimers, have in this garage. The chance is very little but the possible outcome a disaster.
On Aliexpress, you can buy relatively OK pocket instruments under 50 euros. They cannot do alpha radiation, but are sufficient for alerting you there is something radiating. I have BOSEAN FS-600 (some strange chinese brand from Ali), and it works OK, get reading from uranium ore or thorium materials easily. To "make sure", it is sufficient. For some more precise dose calculations and stuff, I wouldn´t rely on that.
