RADIOLOGICAL SURVEY OF THE INACTIVE URANIUM-MILL
TAILINGS AT RIFLE. COLORADO

ABSTRACT
Results of radiological surveys of two inactive uranium-mill sites
near Rifle, Colorado, in May 1976 are presented. These sites are refer-
red to as Old Rifle and New Rifle. The calculated 226Ra inventory of
the latter site is much higher than at the older mill location. Data on
above-ground measurements of gamma exposure rates, surface and near-
surface concentration of 226Ra in soil and sediment samples, concentra-
tion of 226Ra in water, calculated subsurface distribution of 22GRa, and
particulate radionuclide concentrations in air samples are given. The
data serve to define the extent of contamination in the vicinity of the
mill sites and their immediate surrounding areas with tailings parti-
cles. Results of these measurements were utilized as technical input
for an engineering assessment of these two sites.
