[ RadSafe ] IBIS Sr-90 source construction

[Brad Keck]

Hi Brian,

I believe these are electroplated sources, so at the surface of the metal (stainless steel usually in sources) a thin coat of strontium will be reduced to it’s metallic form.

It is important of course that the strontium “plate” be very thin so that beta emissions are unshielded in the direction of the detector….  

Hope this helps..

Brad
