Hi Radsafers,

Any guesses on what the parent nuclide is for Br-82 found in electronic PC
boards which have been exposed to high energy (GeV) photons/neutrons?  I
understand IC chips are doped with selenium and arsenic.  These are "close
by" on the chart of the nuclides.  What would the most likely interaction
be?  Other accelerator labs seen this ?

Thanks in advance.......disclaimer....blah, blah.....
