/sup 226/Ra and /sup 228/Ra in water supplies
An early objective of this study was to develop a method for predicting the concentration of radium in well waters based on the well's location, the details of its construction, and the geological structures it penetrates. However, as in Aurora, Ill., /sup 226/Ra concentrations ranging from 3.8 to 18 pCi/L were found for wells of nearly identical construction located within relatively short distances from each other. Even larger deviations were found for comparisons among cities. The /sup 228/Ra concentration was determined in 140 of these samples and ranged from 0.3 to 32 pCi/L. Data obtained by other investigators in Iowa put the median /sub 228/Ra to /sup 226/Ra ratio at 0.64. Regression analysis, however, does not suggest any meaningful correlation of /sup 228/Ra and /sup 226/Ra. Because high concentrations of /sup 228/Ra have been found in areas with low /sup 226/Ra concentrations and /sup 228/Ra is not detected by gross-alpha analysis, it appears that a large-scale survey of /sup 228/Ra in water is needed.
