Natural radioactivity in rocks of the Modane-Aussois region (SE France).

Malczewski D, Żaba J - J Radioanal Nucl Chem (2011)

Bottom Line: The activity concentrations of (40)K varied from 18 Bqkg(-1) (limestone dolomite) to 392 Bqkg(-1) (calcschist), while those of (232)Th varied from 0.7 Bqkg(-1) (limestone dolomite) to 18 Bqkg(-1) (calcschist).The activities associated with (238)U ranged from 9 (quartzite) to 29 Bqkg(-1) (dolomite).In the investigated rock samples, concentrations of (238)U (ppm) and (40)K (%) had a strong negative correlation.

ABSTRACT

The activity concentrations of (40)K, (232)Th, and (238)U in the characteristic rocks of the Modane-Aussois region (Western Alps, France) were determined using an HPGe gamma-ray spectrometry system. The activity concentrations of (40)K varied from 18 Bqkg(-1) (limestone dolomite) to 392 Bqkg(-1) (calcschist), while those of (232)Th varied from 0.7 Bqkg(-1) (limestone dolomite) to 18 Bqkg(-1) (calcschist). The activities associated with (238)U ranged from 9 (quartzite) to 29 Bqkg(-1) (dolomite). In the investigated rock samples, concentrations of (238)U (ppm) and (40)K (%) had a strong negative correlation.
