High Energy Gamma Emitter

[<L666783@LMSC5.IS.LMSC.LOCKHEED.COM>]

Hello everyone. It's pop quiz time.

Of all the isotopes, which one emits the highest energy gamma? We have a
need for calibration of a wide energy-range detector. Other than Co-60,
and short of letting my fingers do the walking through the pages of the
Rad Health Handbook, I couldn't come up with it off the top of my head.
So, to save a litle time, I thought of the great resource of Radsafe!

Please reply to me directly if you'd like, but this might be of general
interest.
