Title Radiation exposures associated with surface mining for uranium.
Bibliographic information June 1977, Vol.32, No.6, p.523-527. Illus. 10 ref.
Abstract Measurements of external gamma radiation, radon and radon daughters, and uranium aerosols were made at an operating open-pit mine using readily available field survey techniques and instruments. Measurement techniques are discussed. Radiation exposure of various occupational categories, such as excavation equipment operators, truck drivers, equipment maintenance personnel, ore control personnel, and engineering staff, is estimated. These estimates are compared with the results of film badge dosimetry. While the average exposure rate was about 0.5mR/hr ▒0.5mR/hr, it was noted that higher exposures (up to 10mR/hr) were measured in the vicinity of ore bodies containing uranium in the 5% range. Some contamination of earth-moving equipment by uranium-bearing dusts was also noted.
