for the data reduction of all gamma-ray spectra. In GAMANAL, the observed
photopeak in the measured spectra is compared with a library of gamma-ray

fission and activation products and naturally occurring radionuclides to

ne

identify the radionuclides in the sample.

The program then applies correction

factors for sample size, density, counting time, counting geometry, and decay

to convert the measured counting rate to pCi/g of sample on the date of

collection.

The program also generates

an

upper-limit amount of specific

spectral radionuclides based on those spectral regions where signals would be
seen if the radionuclide were present in detectable quantities.
