Re: mystery gamma lines
Tom,
The three largest peaks in the 300-500 keV region (345, 375, and 414 keV)
are all from Pu239. Some of the most abundant peaks in that region are:
Isotope keV
Am241 332.387
Pu239 332.845
Am241 335.422
Pu239 336.096
Pu239 345.011
Am241 368.605
Pu239 375.042
Am241 376.590
Pu239 380.170
Pu239 382.743
Pu239 392.525
Pu239 393.120
Pu239 413.712
Pu239 451.474
Now, back to our regularly scheduled radon/LNT discussion...
