Abstract
A radiological survey was made of the inactive uranium mill site near Riverton, Wyoming during the period September 30-October 2, 1975. The primary purpose of the survey was to delineate areas which are contaminated by windblown material from the tailings pile. Secondary purposes were to collect water samples from local wells, and to collect indoor radon progeny (working level) samples in structures near the site, in order to identify any major radiation exposures which may be occurring through these exposure pathways. The contaminated areas were delineated by making a series of differential gamma exposure rate measurements at the ground surface. A total of about 460 acres, exclusive of the tailings pile, was found to be contaminated above background levels. An area of 30 acres would have to be decontaminated to reduce the maximum residual exposure rate to 40 micro R/hr, and 99 acres would have to be decontaminated to reduce the maximum residual exposure rate to 10 micro R/hr.
