Radiological survey of the inactive uranium-mill tailings at Riverton, Wyoming

PDF Version Also Available for Download.

Description

Results of a radiological survey performed at the Riverton, Wyoming site in July 1976, are presented. The average external gamma exposure rate at 1 m over the tailings pile was 56 ..mu..R/hr. The corresponding rate for the former mill area was 97 ..mu..R/hr. Movement of tailings particles in a dry wash is evident; but it appears that, in general, the earth cover over the tailings pile has been effective in limiting both wind and water erosion of the tailings. The calculated concentration of /sup 226/Ra as a function of depth in 15 augered holes is presented graphically. A survey of ... continued below

A survey of the Teton Division Lumber Company property in Riverton showed a maximum external gamma exposure rate of 270 ..mu..R/hr.
