Bloch and Craig reported in Geology; May 1981; v. 9; no. 5; pp. 195-199 that radioactive (radium-rich) springs discharging in the watershed of a proposed impoundment on Lower Lee Creek in Sequoyah County, Oklahoma, were determined not to represent a significant radiological effect.
The impact of these springs on the proposed lake will be negligible, owing to a combination of the following factors: extremely low rate of discharge of the springs even following periods of heavy rainfall, effective dilution of the spring water by the creek into which the springs discharge (dilution factor of about 1:100), and precipitation of radiobarite just below the mouths of the springs. The spring water probably rises to the surface along a fault and fracture system present in the study area, say NORM?
