Re: Rad Sources for Workshops

I have seen one smoke-detector 241Am source which is somewhow built

at the bottom of something like a brass well (so the source would

be directed).

 The whole thing had 10-12 mm outside diameter, and ended with a screw

at the rear (if the opening for the source is the front) side.

I suppose one could swallow it - but then I imagine anyone wanting

to swallow such a piece of metal would have much bigger, non-radiation

related problems...

 However, the source seemed not so weak; it was doing a 40 or 50 kCps

gamma through the Be window of a 15% HPGe detector... Being non-medical,

I can only stay astonished that such a source would bring no

health issues if ingested. Are the others talking of a weaker

source or are we really designed to withstand that much? Or even

much more than that?
