Wanted: Help interpreting photon spectrum -Reply

Rick

Here would be my guesses:

The 802.96 line is Po-210 (803.10)
The 46.52 line is Pb-210 (46.54)
The 68.80 line is a gold K alpha x-ray (68.794)
The 77.87 line is a gold K beta x-ray (77.978)

And who cares what the 80.17 line is ;-) just kidding.
Maybe its a polonium K alpha x-ray at 79.269

PS.   Some people had trouble with my URL address for the USGS
images of U, Th, and K levels in the US (it works for me). An alternative
is: http://energy.cr.usgs.gov/radon/DDS-9.html
