Nondestructive low-energy photon analysis of environmental samples

Creators

Description

Low-energy photons that accompany the decay of alpha- or beta-emitting radionuclides (e.g., 241Am, 210Pb, and 238U-234Th) may be used to quantify concentrations of these radionuclides in environmental samples. Previous attempts to quantify these low-energy photons have had limited success because of the uncertainty associated with photon attenuation in samples of variable matrix composition. A method for directly measuring and applying the self-absorption correction factor is presented. Results obtained by this nondestructive technique for counting low-energy photons are in agreement with values obtained from intracalibrated samples using radiochemical separations and alpha or beta analysis. 8 references, 1 figure, 3 tables
