Significant concentrations of radium -226, a naturally occurring isotope which has no relationship to fallout, have been detected in a number of deep wells in Iowa. Wells that have significant radium concentrations are located in smaller communities mostly in southeastern part of the State. Several of the towns have municipal zeolite softening processes which remove radium down to low levels. In some cases where the raw well water shows relatively high concentrations, zeolite softened water distributed to the public has had approximately 90 percent of the radium removed. Wells tested so far show that the average radium values are in most instances within the range specified by the Federal Radiation Council.
